Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a layout data creation device used in computer-based platemaking processing of commercial printed matter such as flyers.

(Prior art) In recent years, along with the color separation of documents using scanners, printed matter 1
A layout system for printing plate making that synthesizes image data for pages through computer processing is used in the field of printing plate making. This layout system is a scanner connected to a computer with page editing functions.
Image data taken in by a scanner is given to the computer, subjected to processing such as layout, and then output to the scanner.

FIG. 19 is a schematic diagram showing the configuration of a general layout system for printing plate making. In the figure, 160 is a layout section, 170 is a tablet digitizer, and 180 is a scanner section. As shown in the figure, the layout section 1.60 includes a computer 161 and a memo U 162 connected thereto.
, 1.63 The tablet digitizer 170 is composed of a display 164, a pointing device 165, and a keyboard 166. The tablet digitizer 170 is composed of a cursor 171 and an input surface 172, and a mount area 173 and a menu area 174 are set on the manual surface 172. Scanner section 180
is composed of an input drum 181, an output drum 182, and an interface Ht5.186, and the interface Ht5.186 is connected to the computer 161. Note that the computer 161 includes an input computer, a layout computer, and an output computer (all not shown).

In this layout system, image data layout work is performed in the following manner based on various manuscripts, layout designation sheets, and other instructions.

First, a document is pasted on the input drum 181 of the scanner R180 at an angle specified by the layout designation paper, and the image data of the document is taken into the human-powered computer (not shown) of the computer 161 via the ink face 185 and stored in the memory 162. let Image data is captured from the document in an area slightly larger than the actual trimming area based on a layout sheet (not shown), and accurate trimming is later performed using a layout computer (not shown) of the computer 161.

The memory 162 in which image data has been written is separated from the human computer and connected to the layout computer. As a result, the image data written in the memory 162 is displayed on the display 164. The operator observes this displayed image and operates the pointing device 165 while referring to the layout designation sheet to move the cursor and designate the trimming range, the position of the mesh cover, etc. Further, the keyboard 166 is used to specify the printing surface color, halftone percentage, etc.

The data that has been layout processed according to these specifications is written to the memory 163, so after the writing is completed, the data is
63 is disconnected from the layout computer and connected to an output computer (not shown) of computer 161. As a result, the data in the memory 163 is taken out via the output computer and the interface 1.86, and the trimmed and laid out image is output onto the film set on the output drum 182 of the scanner section 180.

Furthermore, the above operations performed using pointing device 165 and keyboard 166 can also be performed by operating tablet digitizer 170. That is, the above-mentioned layout designation paper is set on the mount area 173 of the tablet digitizer 170, and the cursor 171 is operated to select the position data of the picture drawn on the layout designation paper and various menus set in the menu area 174. Just enter it.

By the way, unlike general printed matter, printed matter for product promotions, generally called flyers, only prints the parts of the subject that appear in the manuscript, and extremely often these subject parts overlap each other. It has characteristics.

FIG. 20 is a schematic diagram showing the layout designation paper on which the specification format of the printed flyer is drawn. In the figure, B is a designated layout sheet, and on this designated layout sheet B there is a figure ε6 consisting of a trimming frame and a sketch image of the photograph part, and figures E3, E4, ε5, E7, E consisting only of the sketch image of the photograph part.
8, B9, ε11, ε12, and figures B1, Snake 2, and εlO indicating the frames of the flat mesh (mesh lining) items are drawn. Further, in the figures El, E2, and ElO, plain halftone information indicating the halftone percentage of each color is written.

As shown, figures E3, E4, E5, B7, ε8, E9
, Ell, and ε12 indicate the outline of the subject portion of the document, and only the subject of the corresponding document will be printed on this portion. To perform this with the layout device 2 shown in FIG. 19, a cutting operation is performed to extract only the subject part from the rectangular image data containing the subject part of the document stored in the memo 1J162. There is a need.

FIGS. 21(a) and 21(b) are schematic diagrams for explaining this cutting operation, and here, the cutting operation of the image data of the document corresponding to figure B7 in FIG. 20 will be explained.

The cutting operation is performed by operating the pointing device 165 on the image 11 displayed on the display 164 as shown in FIG. 21(a) and moving the cursor 167 along the outline of the person in the image 11. It will be done.

However, the image 1 displayed on the display 164 is a display of the whole image by thinning out the image in the memory 162, and if the cursor 167 is operated on this whole image, the precision of the outline will deteriorate. There is a problem.

For this reason, for printed matter that requires high quality, the second
As shown in FIG.
7 must be moved to perform the above-mentioned cutting operation.

However, the disadvantage is that the cutting operation performed by displaying the entire image or partially enlarged image on the display and operating the cursor is complicated and time-consuming. In particular, for printed matter such as flyers, the format of the designated paper, the types of products to be featured on the flyer, and their selling prices are often not determined until the flyer is due to be distributed, and the time spent on plate making and printing is limited to magazines, etc. The actual situation is that the number of documents is extremely small compared to general printed matter, and the time from submission to plate making, printing, and delivery is only a few days. However, there is a problem in that the delivery date cannot be met if the product is not delivered in time.

Additionally, some layout systems have a function that automatically cuts out the image using the difference in density between the subject and its background, but if there is a clear 1 degree difference between all the outlines of the subject. There is a problem in that there are only a few such documents, and while it is possible to automatically cut out some parts of the image, the remaining parts have to be cut out as described above.

In this way, the layout system shown in FIG. 19 cannot be applied to the plate-making process for printed materials such as flyers.
In reality, layouts are being done manually using various masks, and the reality is that streamlining of leaflet making is lagging behind.

As a solution to the above problems, the patent application filed in 1982
-233400 and Japanese Patent Application No. 62-233401, rough cutout data is given to the layout system, and based on this cutout data, layout processing for one page of printed matter is performed, and the final image data is finalized in units where the image data does not overlap. The applicant has proposed a system for creating an original plate (hereinafter referred to as "separation"), which is a stage prior to creating a standard original plate.

(Problem to be Solved by the Invention) However, in the systems proposed in Japanese Patent Application No. 62-233400 and Japanese Patent Application No. 62-233401, layout data to which separation instruction data is added is directly input to the layout system. Since page make-up processing is performed in units of separations, if this separation instruction data is incorrect, separation defects such as overlapping images or figures will occur in the created separations, and page make-up will be delayed. There is a period Z during which the up process must be redone.

The present invention has been made in consideration of the above-mentioned problems, and it is possible to correct errors in the separation instruction data for layout data to which separation instruction data has been added, and to create layout data free of separation defects. The purpose is to provide equipment.

Also, 19 is an angle display, 21 is a cursor, B is a layout designation sheet, and I is a document ho? A projection of the original set on the card 15 (this is an image).

Here, in the magnification measuring means 11, the projection lens 14,
The original holder 15 and the lamp/south 16 are held together by the support 13, and the surface of the layout designated paper B placed on the surface of the workbench 12 is used as the projection surface of the image of the original. The original placed in the original holder 15 is illuminated by a light source provided in the lamp house 16 through a suitable condenser lens, and a projected image I of the design is projected onto the surface of the assigned sheet B. It looks like this. The projection lens 14, the original holder 15, and the lamp house 16 are configured to be movable up and down along the support 13, and are moved up and down by operating a switch on the operation control panel 17. A projection image I obtained by reducing or enlarging the image of Take in the distance between paper B using a linear enhancer etc.
The magnification is calculated through arithmetic processing and displayed on the magnification display 18. Therefore, the transparent original is placed in the original holder 1.
5 [7] If the projected image I is made to match the figure drawn on the assigned sheet of paper, the magnification will automatically be displayed on the magnification display 18, and the magnification measurement can be completed. Note that such a magnification measuring means 11 is well known.

FIG. 3 is a flowchart for explaining the control operation of the computer 22, and FIG. 1 is a schematic diagram for explaining the relationship between the two, and the operations of creating the first layout data and creating the sheet W will be described below based on the diagram.

First, prior to measurement, an operator determines the overlapping state of the figures drawn on the designated layout paper, and groups the documents in units of color separation. For the layout designated paper shown in Figure 16, B3
,B4,B5,l! 7, B8, Snake 9.610.81k
, ε12 are overlapping or adjacent figures, and the manuscripts corresponding to these figures are divided into groups,
As a result, the figure El.

Documents corresponding to C2, C3, B5, B6, B7, B9, and ε12 are in the first group, and shapes B4.88.810,
The manuscript corresponding to Ell is sorted into the second loop.

For the originals grouped into separation units in this way, the original Nα, the separation Nα, and the scanner resolution are waited for to be input from the keyboard 23 (Sl), and when they are input, the magnification data from the magnification measuring means 11 etc. It waits for position data to be input from the data tablet 20 (B2). The scanner resolution is inputted as a predetermined value, which is usually 10 to 20 lines/III.

Inputting the magnification data is done by matching the projected image of the document with the figure on the layout designation sheet B as described above, or by inputting the value displayed on the magnification display 18 directly from the magnification measuring means 11 or by inputting the value displayed on the magnification display 18 into the keyboard 31. This is done by inputting from .

In step S2, as shown in FIG. 4(a), the position data of each point on the xY coordinate axes of the data tablet 20, that is, the reference point PO drawn on the designated sheet of paper and the plate line H (of the scanner) The coordinate values of the two points P1 and P2 on the reference line (corresponding to the reference line when pasting the original on the manual drum),
Coordinate values of the apex A1, exSct, 01 of the rectangle forming the document outline in the projected image (the figure shows the projected image of the document corresponding to the figure ε3 shown in FIG. 20), the apex 11 of the cutout figure, The coordinate values of Jl, K1, and Ll and the coordinate value of a specific point TI, which will be used later when positioning the image, are input.

Next, the first layout data creation means 22b creates first layout data for each separation based on the data manually input in steps S1 and B2 (S3L first layout data creation means 22b creates the first layout data in units of separations based on the data manually input in steps S1 and B2). T point P1 shown in ta)
, P2, the inclination θ with respect to the hanmen-1HOX axis is calculated, and the apex 11, Jl, of the cutout figure is calculated.
1, coordinate values of Ll:) Vertices E1, Fl, G1, Hl of the rectangle indicating the trimming range as shown in Fig. 4(a)
Calculate the coordinate values of the point PO

Calculate the coordinate values of ``gl, hl, eye,'' 1Sk1, IL tl, and combine these calculated coordinate values with steps SL and B.
In step 2, first layout data is created in which the manually generated manuscript seed, separation seed, scanner resolution, and magnification data are associated with each other. Next, the drawing data calculation means 22a calculates drawing data (B4). The drawing data is the drawing coordinate values of the outline of the document and the trimming frame drawn on the sheet W, and points a1, bl, C1, dl, el shown in FIG.
, fl, gl, and hl divided by the magnification value input in step S2.

Regarding the coordinate values of the trimming range, in the case of a cutout figure, the coordinate values of the figure indicating the trimming range are calculated from the coordinate values of the cutout figure as described above without being manually inputted from the data tablet 20, but as shown in FIG. If the figure is not a cut-out figure like the figure E6 shown in FIG.

When the drawing data is calculated in this way, it is determined whether or not the measurement of the document is finished (S5). If it is not finished, the process returns to step S1 and processes from step S1 onward are performed on another document, and the process ends. If so, output the first layout data created in step S3 (S6L).Furthermore, output the drawing data calculated in step S4 (S7).
, based on this output drawing data, the plotter 26
Draw outlines, trimming frames, etc. of each document on W. Note that the drawing position on the sheet W is determined automatically based on preset drawing parameters or according to instructions from the operator.

FIGS. 5(a) and 5(b) are schematic diagrams showing the contents of the first layout data output in step S6 of FIG. 3, and FIG. FIG. 4B shows each data of the manuscript belonging to the second group.

As shown in the figure, each piece of data is correlated in units of color separation for the manuscripts Nα1 to Nα9 measured. Here, "contour line", "trimming frame", "cutout", and "specific point" are the coordinate values of each point in the xy coordinate system as shown in FIG. 4, etc.). The first layout data shown in FIG. 5 is recorded on floppy disks FIIIA and F[11B by the floppy disk drive 33,
The data of separation Nα1 shown in figure (a) is a floppy FDI.
The data of the separation Nα2 recorded in A and shown in FIG. 4B is recorded in the floppy FDIB. By creating a floppy disk for each separation in this way, it becomes easier to operate the layout later, but if the number of floppy disks increases and the operation becomes complicated, it is necessary to create layout data for different separations Nα on the same floppy disk. That is, Fig. 5(a)
, et al.) may be recorded.

Note that the position data of the "cutout" is not limited to position data representing a rectangle as shown in FIG. 5, but may be position data of a polygon. By making the shape of the cutout polygonal, it is possible to fit the cutout image closer to the object into one separation.

FIG. 6 is a schematic diagram of a sheet W created by the plotter 26 based on the IfM image data output in step S7 of FIG. 3. As shown, a reference line 301 is drawn at the top of the sheet W. Furthermore, the outline ai 1302 and trimming frame 303 of each original are drawn at predetermined positions, and the original Na 30 is drawn near these original outlines and trimming frames.
(Ill and a magnification value of 300m are drawn. This sheet W is created in separation units as in the first layout data above. Then, the operator places each original on the sheet W along the original outline 302. The sheet W with the original pasted thereon is set on a manual drum of a layout scanner (described later), and the image data manual range of each original, that is, the scan range is set based on the trimming frame 303.

FIG. 7 is a schematic diagram showing the input surface 42 of the data tablet 410 provided in the copy mount information creation device 40. As shown, the manual surface 42 has a mount area 42a, a first menu area 42b, and a second menu area. A region 42c is set. The mount area 42a is set by inputting three points M1, M2, and M3 using a cursor (not shown) in accordance with the block mount created based on the designated layout paper length shown in FIG. In the first many area 42b, figures frequently used on the data tablet 41 are set as items. Here, the items are rectangles, circles, polygons, and straight lines. The second menu area 42c includes layout items such as pattern number, magnification (%), halftone → halftone %, live ink color, printing surface color, specific point, terminator, operational items such as end point, and C( Color items such as (cyan), Y (yellow), M (magenta), and K (black) are set, and in these items, θ to 9, a decimal point, and TAB indicating the delimitation of numerical values are set for manual numerical input.

Next, operations for inputting various positional data and layout data on the data tablet 41 will be explained. In this case, the block mount is an accurate trace of the layout finalized for plate making based on the specified layout paper length, but for the sake of explanation, the layout specified paper B shown in Fig. 20 is used as the block mount. do.

First, the plate surface coordinates, which are the coordinates of the mount area, are input. This is done by inputting points M1 to M303 shown in FIG. 7 with a cursor. Next, the color of the printing plate is manually colored. For example, if the plate color is cyan lO%, move the cursor to select “plate color”, “C”, “1”, “O” in the second menu area 42c.
” and “τΔB” are sequentially specified.

After inputting the plate color, input the figure.

The figures refer to figures indicating the trimming range and other figures drawn on the stencil mount. For example, if the figure is a rectangle like B1, "
Rectangle", the two similar points at the upper left and lower right of the figure E1 are manually entered using the cursor. This figure can be either a picture or a mesh. In the case of a picture, image data is imported from the original, and in the case of halftone dots, it is filled in with a predetermined color. In the case of halftone dots, the color and separation Nα of the halftone dots are manually performed. The figure 81 is a steel block, its mesh percentage is cyan 100%, and its separation Nα is 1.
0”, “0”, rTABJ, followed by r separation Nα
”, “1”, rTABJ. In the case of the figure E6, since it is a picture, the picture number, scaling factor (magnification), and specific point are input. Since the color separation Nα is input from the data tablet 20 of the scanner original pasting sheet creation device 1, there is no need for manual input on this data tablet 41. Input the pattern number: “Picture number”, “4”, r
Perform the operation TABJ (in the case of picture number 4). Input the magnification rate: “variable magnification”, “1”, “2”, rQJ, rT
Operate with ABJ (when the magnification is 120%).

The specific point manual refers to a predetermined point on the block mount following the "specific point." This specific point is manually applied to the figure whose design is drawn on the block mount. In addition, if specific points have already been input from the magnification measuring device IO based on the layout designation paper, the specific points will be input redundantly, but for the sake of accuracy, the specific points input from the data tablet 41 will be considered valid. do. Here, the above picture number is the same as the manuscript number input in step S1 of FIG. 3, and the input of the magnification ratio will be omitted if the magnification data is entered manually in step S2 of FIG. 3. . Also, the figures ε3, B4, [i
5, B7, B8, B9, Ell.

In the case of a cutout figure such as B12, the coordinate values of the figure indicating the trimming range are not input, and only the picture number and specific point are entered manually. Note that if there is a live rule representing the ruled line to be actually printed, the color of the live rule is input. This is done with "Ikisumiiro", "M", "5", "0", rTAB" (
In the case of Ikisumi M50%).

The "terminator" in the second menu area 1lt42C is for returning to the starting point of the input operation, and by specifying the "terminator" the above-mentioned operation can be performed on a new figure.

Further, when "end" is instructed, data input from the data tablet 41 is ended.

In this way, the second layout data creation means 4 is based on the data manually inputted from the data tablet 41.
3a creates the second layout data based on the block copy mount, but the data input here is also manually input in units of separations like the first layout data, and the second layout data is created in units of separations. .

FIGS. 8(a), 8(C) are schematic diagrams showing the contents of data created by the second layout data creating means 43a, and FIG. The data corresponding to plate separation 1, and the data corresponding to plate separation NQ2 shown in No. 5rXJ(b) are shown. Figure 8(a),

, E4.85, ε7, B8, ε9, ε11, and ε12, only data of specific points are given.

Note that for the second layout data, as with the first layout data, by creating a floppy disk for each separation, operations in the subsequent layout will be easier, but if the number of floppy disks increases, the operation will become more complicated. Alternatively, the layout data of different separation Nas, that is, the data shown in FIGS. 8(a) and 8(b) may be recorded on the same floppy disk.

FIG. 9 is a flowchart showing the control operation of the separation layout data creating means 32a shown in FIG. 1, and the creation of the separation layout data will be described below based on the figure.

First, the first layout data recorded in the floppy FOI^ and FDIB is read out via the floppy disk drive 31 (521), and then the first layout data is read out from the floppy FD2A.
, reads out the second layout data recorded in FrJ2B (S22).

Next, the read first layout data and second layout data are checked for originals (S23).

Create figure data based on the cutout data of the first layout data shown in a) and (c) 525) If the type of figure is "standard shape", create the figure data based on the cutout data of the first layout data shown in FIG. 8(C). Graphic data is created based on the regular graphic data (S26). New layout data is created by merging the two types of graphic data created in this way with the "flat net report" and "specific point" other than the data related to the graphics shown in Figure 8 (C). S27).

Here, the graphic data created in step 326 is
As shown in Figure (C), its position has been determined, but since the graphic data created in step S25 has only a shape and its position has not been determined, it is necessary to perform its positioning. This positioning is performed at specific points t1 to t9 shown in 5th tm (a) and
Document N whose specific points 1 to U9 were compared in step S24
This is done by making a correspondence regarding α. Next, it is determined whether or not to continue (S28), and if it is determined to continue, the process returns to step S23, and step S28 is performed for the remaining manuscripts.
Processing from step 23 onwards is performed.

In this way, by repeating the data merging in step S27 for the manuscripts collated by Nα in step S23, layout data for one entire page of printed material is created. Layout data is created in units of separations. That is, the fifth
The data of the floppy F[]lA shown in Figure (a) and the data of the floppy FD2A shown in Figure 8(a) are merged to create the layout data of the separation Nα1, and the layout data of the separation Nα1 is created.
The data of the 101st day of the floppy shown in FIG. 8 and the data of the floppy FD2B shown in FIG. 8 are combined to create the layout data of the separation Nα2. When data is merged in step 327 for all manuscripts in units of separations, rNo.1 is determined in step 528, and the layout data in units of separations obtained by repeating the processes from step 523 to step 527. is temporarily stored in the magnetic disk 36 as layout data for separation (S2
9).

FIGS. 10(a) and 10(a) are schematic diagrams showing data created by the separation layout data creation means 32a as described above. In this case, FIG. 10(a) shows data regarding the separation Nα1, and the separation data Sε1 is obtained by cutting out [1if-1′Lε3,
Lε5, LE7, Lfi9# Yobi Ll? 12, and fixed figure data L[! from the second layout data. 1, Lε2
and 1,86. Figure 10 et al.] shows data for separation Nα2, and separation data St! 2 is composed of cutout figure data LB4, LB8, and LBII from the first layout data, and regular figure data LBIO from the second layout data. As shown in the figure, the graphic data of the separation data SEI and SF3 are associated with the data of the specific points u1 to U9 from the second layout data.

The separation layout data created in this way and stored on the magnetic disk 36 is checked and corrected by the separation instruction modification means 32b.

FIG. 11 is a schematic diagram showing the state of the display screen of the display 35 used when checking the modification of the separation layout data. As shown in the figure, the screen 36 is composed of a menu area 37 and a figure display area 38. Menu 37c1 for specifying the seed of the figure to be modified
Menu 37d for specifying the separation demon to be corrected,
It consists of a menu 37e for manually inputting the figures Nα and separation Nα to be pressed, and a menu 37f for instructing the end of the operation, and each menu 5-37b to 37f
"Partial enlargement j1" figure NtxJ, r separation Na J, rQ1=-9J, r end j are displayed respectively.

FIG. 12 is a flowchart showing the control operation of the separation correction means 32b shown in FIG. Yes, the operation of checking the modification of the separation layout data will be explained below.

First, the layout data for plate separation stored in the magnetic disk 36 is read out (531), and the process waits for the plate separation machine to be operated manually (S32). This separation seed is input by operating the pointing device 34 to point to the menu 37d on the display 35, and then pointing to a number in the menu 37e. When the separation Nα is input, the graphic information of the separation Xα that has been manually input is displayed in the display area 38 of the display 35. For example, manually created separation N
When α is "l", a figure as shown in FIG. 13 is displayed on the third display area.

Next, it is determined whether or not to modify the separation instruction data for the displayed figure information (S34), and if "rYes", the separation instruction data, that is, the separation: Jα for the corresponding figure is corrected (S35). .

This correction of the separation instruction data is performed by the operator determining the overlap of the figures displayed on the display 35 and operating the pointing device 34 to point to the menu area 37. Specifically, after the separation demon instructs menu 37c for the incorrect figure, menu 3
The user specifies the figure to be corrected by specifying the number 7e, and after specifying the menu 37d, selects the menu s 37e to input the correct separation value Nα. In the example shown in FIG. 13, since the separation Nα of the figure Nα8 is erroneously set to “1”, the figures LE7, LE8, and LB9 are displayed on the display 35 in an overlapping manner, and the operator has to read the separation instruction data of the figure Nα8. can easily be confirmed to be incorrect. Therefore, when the operator points the pointing device 3
4 to correct the separation Nα of the figure Nα8 to “2”, the separation instruction data in step S35 is corrected. At this time, if the overlapping state of the figures displayed on the display 35 cannot be determined, the overlapping state of the figures can be easily determined by partially enlarging and displaying the displayed figure using the menu 37b. can. The instruction for the figure to be enlarged is made by operating the pointing device 34 to specify the menu 37b, and then using the cursor (not shown) displayed in the display area 38.
This is done by moving the figure to indicate the figure to be enlarged.

The layout state of the figure after the separation instruction data has been corrected in this way is displayed again on the display 35 (S
33) Then, it is determined whether or not to modify (S34)
, rYes J, the separation instruction data is corrected again in step S35, and in the case of "NO", it is determined whether or not to continue checking the correction of the separation layout data (
S36). If "rYes", step S32
The process returns to and waits for the separation NCL to be input. When the processing of steps S32 to S36 is repeated and the confirmation of the layout data for all separations is completed, that is, in the case of "rNo" in step S36, the floppy disk drive 31 is transferred to the floppy FD3 shown in FIG.
^, Record the corrected separation layout data on the FD3B (S37). In this case, the data for separation Nα1 is recorded on the floppy FD3^, and the data for separation Nα2 is recorded on the floppy FD3B, but the data for separation Nα1 and Nα2 may be recorded on the same floppy disk.

In addition, when correcting and confirming the above separation layout data, the operator judges whether or not the separation instruction data is correct based on the overlapping state of the figures displayed on the display 35. A function for determining data overlap may be provided so that the computer 32 determines whether or not the separation instruction data is correct. If you let the computer make the decision, you can blink the figures on the screen 36 of the display 35, invert the display color, or simply display a message for the figures for which the separation instruction data is incorrect, that is, the figures that overlap. Bye.

The layout data for separation created as described above is given to the layout system, and page make-up processing is performed for each separation.

(not shown) are connected.

Next, a description will be given of the manual operation of the image data of a document in the layout system 50, the layering process of the manually input image data, and the output operation of the layout-processed image data.

FIG. 15 is a flowchart showing the control operation of the input computers 55^, 558, and FIG. 16 is a schematic diagram of a magnetic disk that stores manually input image data.
The input of image data of each document will be explained below based on the figures. In this case, a predetermined original is pasted on the sheet W created in advance by the scanner original pasting sheet creation device 1 in units of color separations, and the sheet W corresponding to color separation k1 is pasted on the input drum 51. In A, it is assumed that the sheet V/ corresponding to separation: 敞2 is set on the manual drum 51B,
Image data is input using floppy PDIA.

This is performed based on the first layout data recorded in the FDIB.

First, floppy disk drives 56A and 56B
The first layout data is read out from the floppy FDIASP port IB set in the floppy disk (541), and the original iNα is manually input for the document from which image data is to be read (542). Once input is input, the input size is set. (S43).

The input of the original I Nα is performed by an operator operating a console (not shown). Input size 1 indicates the range in which the scanning head attached to the input drum 51^, 51B scans the original, and the floppy FDI^, FDI
It is calculated from the trimming frame and magnification data written in the input card 51. A, 51B
This is done by the operator instructing the scanning start point in the circumferential direction and axial direction. Here, the human-powered drum 51
A, 51. The manual size can be easily set by specifying the scan start point among the vertices of the trimming frame drawn on B) and W. When this manual size setting is completed, the image data calculation means 55a calculates the amount of image data (S14). The image data amount corresponds to the amount of data in the magnetic disk 66 when image data obtained by scanning a document is stored in the magnetic disk 66, and is based on the human power size input in step S43 and the data read out in step 541. It is calculated from the scanner resolution in the first layout data.

Next, a console (not shown) connected to the input computers 55^, 55B waits for the disk drive to store image data from the plurality of magnetic disks 66 (545), and the disk Nα is Once input, the data storage area setting means 55b performs step S45.
Set a data storage area in the magnetic disk identified in step 544 to store the image data calculated in step 544 (
Si6).

This data storage area setting is performed for the area in the magnetic disk identified in step S45 where image data is not yet stored or where no data storage area has been set yet.

For example, as shown in FIG. 16, the magnetic disk 66 is 1J
In the case where cL1 to cL5 are provided, if seed 1 is manually input in step S45 and image data is already stored in areas IMI to IM3 on the disk of Nα1, then in step S46 the image data calculated in step 514 is An area IM4 for storing image data is set.

Thereafter, after various scanner disassembly conditions are set, the manually powered drums 51^ and 51B are rotated to manually scan the document specified in step S42 using the scanning head (not shown) (S47), and the interface 53 is manually scanned. The image data is captured in the area set in step 546 of the disk specified in step S45 (348). Next, it is determined whether or not to continue (S49). If the process is to be continued, the process returns to step S42 and the processes from step S42 onward are performed on the remaining documents; if not, the process ends. In this case, the image data of the original corresponding to the separation NQI is taken in from the input computer 55^, and the image data of the original corresponding to the separation Nα2 is taken in from the human computer 55B.

In this way, by inputting the image data of the manuscript necessary for the layout based on the first layout data for each separation unit from the scanner manuscript pasting sheet creation device 1, it is possible to save time before the original mount is completed. In addition, by operating a plurality of input drums, input computers, etc., manual processing of the document can be performed in parallel in units of color separations.

In the above embodiment, a plurality of floppies on which the first layout data is recorded, an input drum, a human computer, etc. are used to input the image data of the manuscript in units of separations. The first layout data of different separations may be recorded on a floppy disk, and the image data of originals of different separations may be manually processed using the same manual drum, computer, etc. In addition, the data given to the input computer 55^, 55th via the floppy disk drives 56^, 56B is transferred to the floppy disk drive 56^, 56B.
%FD3B may be the layout data for color separation, and this layout data for color separation may be data for different color separations recorded on the same floppy disk.

Next, the control operation of the layout computer 600 will be explained in detail.

Next, the image positioning means 60a moves as shown in FIG. 10(a), (
The read image data is positioned according to the separation data shown in b) (S53). Positioning of the image data is performed by displaying the image data read out in step S52 and the graphic data corresponding to this image data on the display 62 so that their center points coincide, and determining the position of the specific point displayed at the same time. This is done by determining the That is, if the relative position of the displayed image and the figure is correct, the position of the specific point at this time is taken as the image position; if it is incorrect, the position of the specific point is corrected by operating the pointing device 63, and the corrected specified point is The position of the point is assumed to be the position of one image. The image positioning data created by the image positioning means 60a in this way is stored on a floppy FD3A.
The data is stored in the FD3B (S54).

Thereafter, the makeup image data creation means 60b reads out the separation layout data and the positioning data determined in step S53, that is, the specific point data, from the floppies FD3A and FD3B, reads out each image data from the magnetic disk 66, and reads out the image data from the floppy disk FD3A and FD3B. ^, FD
The image data read out is trimmed and positioned based on the data of 3B, and the layout for one page of printed matter, that is, makeup processing is performed (S55).
, this makeup image data is stored in the magnetic disk 67 as makeup image data (S56).
