Description

  The present invention relates to an image forming apparatus and a program.

  In an image forming apparatus such as a printer, the input print job (print data) cannot be faithfully printed (reproduced) mainly due to the physical characteristics of the image forming apparatus, or the intention of the user who generated the print job May result in a different print result. For example, in an image forming apparatus that uses C (cyan), M (magenta), Y (yellow), and K (black) inks or toners, a color in an RGB color space, which is a wider color gamut than the CMYK color space, is included in a print job. May be specified, a color specification that cannot be printed by the image forming apparatus may be included. In addition, although printing is possible, for example, a 1-dot line, the appearance may vary greatly depending on the image forming apparatus, that is, a printing result unintended by the user may be obtained.

  Conventionally, a preflight process for notifying (warning) a user of a defect in the print result as described above prior to the print process is known. For example, Patent Document 1 discloses an apparatus that outputs a warning to a user when there is a problem with a print job due to preflight processing.

JP 2010-66987 A

  The preflight process mechanically determines whether or not a print instruction satisfying a predetermined condition is included in a print job. Therefore, even if it is determined that an error has occurred due to the preflight process and a warning is output, there are those that allow the print instruction to be accepted by the user. Therefore, an allowable content warning may be output every time the preflight process is performed. In such a case, it is very complicated for the user to confirm or judge the content of the warning every time the preflight process is performed. .

  An object of the present invention is to reduce the load on the user for checking the preflight processing result as compared to the case where all warnings are output when a print job includes a print instruction that satisfies an error condition.

An image forming apparatus according to the present invention includes a preflight processing unit that performs a preflight process on an input print job, and a print instruction that satisfies an error condition is detected in the print job by the preflight process. Warning means capable of outputting a warning to the user prior to the printing process of the print job, input means for inputting information indicating whether the user can accept the print instruction that satisfies the error condition, Storage means for storing response history information including contents of a print instruction satisfying the error condition included in the input print job and information indicating whether or not the user accepts the print instruction. in after the print instruction filled is allowed, by referring to the response history information, print instruction in the past contained in the input print job If volume is error conditions are satisfied, the warning means without changing the error condition has a first operation mode which does not output the warning, characterized in that.

Preferably, after the print instruction that satisfies the error condition is permitted, the response history information is referred to, and if the print instruction included in the input print job satisfies an error condition that has been permitted in the past , The apparatus further includes an operation mode switching unit that switches between the second operation mode in which the warning unit outputs the warning and the first operation mode.

Desirably, before Symbol second operation mode, said warning means, if the print job including the error satisfies print instruction is input, outputs the response history information together with the warning, corresponding to the error condition To do.

  Preferably, in the second operation mode, the warning unit includes the contents of the print instruction that satisfies the error condition included in the input print job and the print that satisfies the error condition included in the past print job. A warning with a different content is output according to a comparison with the content of the print command that is an instruction and allowed by the user.

Program according to the present invention causes a computer of an image forming apparatus, a preflight processing means for performing the preflight process on an input print job, by the preflight process, an error condition is satisfied print instruction in the print job In order to input warning means capable of outputting a warning to the user prior to the print processing of the print job and information indicating whether the user can accept the print instruction that satisfies the error condition. And a storage means for storing response history information including information indicating the content of the print instruction satisfying the error condition included in the input print job and information indicating whether the user can accept the print instruction. is, the computer of the image forming apparatus, after which the print instruction satisfies the error condition is tolerated, before Referring response history information, print instruction if allowed error condition is satisfied in the past, the first operation mode in which the alarm means without changing the error condition does not output the warning included in the input print job It is made to operate as.

  According to the first or fifth aspect of the present invention, compared to the case where all warnings are output when the print job includes a print instruction that satisfies the error condition, the load on the user for checking the preflight processing result is reduced. The

  According to the second aspect of the present invention, it is possible to select whether or not to output a warning again when the print job satisfies an error condition similar to an error condition permitted in the past.

  According to the third aspect of the present invention, when the current print job includes a print instruction that satisfies the error condition, the user can determine the contents of the print instruction that has satisfied the error condition in the past, and whether the print job is acceptable or not. With reference to this, it is possible to determine the action of the current print job.

  According to the fourth aspect of the present invention, a warning having an appropriate content can be output to the user.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described with reference to the drawings.

<Basic embodiment>
FIG. 1 is a schematic configuration diagram of an image forming apparatus 10 according to the present embodiment. The image forming apparatus includes a print job receiving unit 12, a preflight processing unit 14, a RIP processing unit 16, an output unit 18, a storage unit 20, an input unit 22, a display unit 24, and a control unit 26.

  The print job receiving unit 12 receives a print job from another terminal. The print job receiving unit 12 includes a communication unit such as a LAN card or an external connection interface, and receives a print job from a terminal connected to the image forming apparatus 10 via a network, for example. For example, the print job is data in which a document to be printed is expressed in a page description language (PDL) such as Post Script. Specifically, the print job includes characters, shapes, images, and color information and position information included in a document to be printed. That is, it can be said that the print job includes information indicating a plurality of print instructions for instructing the output contents to the output unit 18 (hereinafter simply referred to as “print instructions”). In this embodiment, it is assumed that color information is expressed in an RGB color space in a print job.

  The preflight processing unit 14 analyzes the print job received by the print job receiving unit 12 prior to the printing process, and describes a print instruction that satisfies a predetermined error condition in the print job (hereinafter referred to as “error print instruction”). It is determined whether it is included).

  The error condition is set in advance based on the physical characteristics of the output unit 18 that performs the printing process, and information indicating the error condition is stored in the storage unit 20. The error condition may be set manually by the user or the administrator of the image forming apparatus 10, or may be automatically set from the physical characteristics of the output unit 18.

  For example, when the output unit 18 uses CMYK toner, it is impossible to reproduce the luminances of the R (red), G (green), and B (blue) colors expressed in the RGB color space. As the error condition, a condition that a print instruction with a predetermined luminance is included in any of R, G, and B is set. Further, for example, when the output unit 18 cannot suitably output a thin line having a predetermined thickness or less, a condition that an instruction for printing a thin line having a predetermined thickness or less is included as an error condition.

  In the present embodiment, error conditions include “includes a print instruction with a luminance of 90% or more in R”, “includes a print instruction with a luminance of 90% or more in G”, and “depends on a luminance of 90% or more in B. “Include print instruction” and “Print job contains print instruction of thin line with thickness of 2 dots or less” are set.

  The RIP processing unit 16 performs processing for converting the print job that has been subjected to the preflight processing by the preflight processing unit 14 into a raster image that can be recognized by the output unit 18.

  The output unit 18 executes print processing. The output unit 18 includes various members of a general printer, such as toner, a photosensitive drum, and a paper feeding unit.

  The storage unit 20 includes, for example, a hard disk, a ROM, or a RAM, and stores a program for operating each unit of the image forming apparatus 10 or information indicating the above error condition. Alternatively, the storage unit 20 temporarily stores the print job received by the print job reception unit 12. The response history DB 28 and response setting information 30 stored in the storage unit 20 will be described later.

  The input unit 22 includes, for example, a touch panel or buttons, and is used to input user instructions to the image forming apparatus 10.

  The display unit 24 is composed of a liquid crystal panel, for example, and displays a user interface or a processing result of the preflight processing unit 14.

  The control unit 26 is configured by, for example, a CPU or a microprocessor, and performs control to operate each unit of the image forming apparatus 10 in accordance with a program stored in the storage unit 20. The control unit 26 outputs a warning to the user when an error print instruction is detected in the print job as a result of the preflight processing by the preflight processing unit 14. In the present embodiment, the control unit 26 displays a warning display on the display unit 24. That is, the control unit 26 functions as a warning unit.

  The schematic configuration of the image forming apparatus 10 is as described above. Note that the preflight processing unit 14 and the RIP processing unit 16 may be functions of the control unit 26 (that is, the preflight processing unit 14 and the RIP processing unit 16 may be included in the control unit 26). ).

  Hereinafter, the processing flow of the image forming apparatus 10, in particular, the processing of storing response history information in the response history DB will be described with reference to FIG. 2 and FIG. 2. FIG. 2 is a flowchart showing a flow of processing in which response history information is accumulated and stored in the response history DB.

  In step S <b> 10, the preflight processing unit 14 performs preflight processing on the print job received by the print job receiving unit 12.

  In step S12, the control unit 26 determines whether or not an error print instruction is detected in the print job as a result of the preflight process for the input print job. In the present embodiment, the print job includes a print instruction indicating that printing should be performed at a luminance of 90% or higher in any of R, G, and B, or printing that a thin line of 2 dots or less should be printed. It is determined whether or not an instruction is included.

  If no error print instruction is detected in the print job in step S12, the preflight process is terminated as it is, and the print job is processed by the RIP processing unit 16 and then printed.

  If an error print instruction is detected in the print job in step S12, in step S14, the control unit 26 includes error conditions that have been allowed by the user in the past among the error conditions satisfied by the current print job. It is determined whether or not. Details of the processing content of step S14 will be described later. Here, it is assumed that all the error conditions satisfied by the current print job are not allowed in the past, and the process proceeds to step S16.

  In step S16, the control unit 26 displays on the display unit 24 a warning display for notifying the user that the print job includes an error print instruction, and displays a screen for allowing the user to input a sample print instruction. This is displayed on the unit 24. FIG. 3 shows an example of such a screen.

  As a result of the preflight process, which part (which print instruction) in the print job satisfies which error condition is specified. In the example of FIG. 3, it is shown that an image having an R luminance of 92% (R92%) exists in an image of 5 cm × 5 cm arranged at the coordinates (10 cm, 10 cm) of the first page. Further, it is shown that a thin line of 2 dots exists in the coordinates (20 cm, 20 cm) on the first page with a length of 5 cm from the right.

  When the user clicks “Yes (Y)” on the touch panel on the screen, in step S18 (see FIG. 2), the control unit 26 determines that a sample print instruction is received from the user, and in step S20, the output unit 18 Prints the print job as a sample (for example, prints only one copy). If the user selects not to perform sample printing, the preflight process is terminated as it is.

  After sample printing, in step S22, the control unit 26 displays a screen for allowing the user to input permission / inhibition for each detected error printing instruction. FIG. 4 shows an example of such a screen.

  As shown in FIG. 4, check boxes corresponding to “Yes” and “No” are provided for each detected error printing instruction, and the user can accept the error printing instruction detected from the current print job. Check “Yes” when it is not, and check “No” when it is not acceptable.

  Even when an error print instruction is detected by the preflight process, when printing is actually performed, the influence may not be felt so much in the printed product. That is, there are cases where the user can accept an error print instruction. The user determines whether or not the detected error printing instruction is acceptable by checking the actually printed sample printing result. In the present embodiment, it is assumed that the user determines that a print instruction relating to R92% is allowed and a print instruction relating to a 2-dot thin line is not allowed.

  In step S24, the control unit 26 causes the response history DB 28 to store the error print instruction detected in the print job and information indicating whether the user can accept the error print instruction.

  FIG. 5 shows an example of the response history DB 28. In the response history DB 28, information indicating an error printing instruction detected in the past and information indicating whether or not the user is allowed are stored in association with each other. Also, there is information indicating the time at which the error print instruction and its admissibility are registered, the document name of the document corresponding to the print job including the error print instruction, and the name of the user who has input the print instruction for the print job. Associated. Preferably, an error condition corresponding to the error print instruction is also stored in association with the error condition.

  In the present embodiment, the response history DB 28 has a table format, and the above information is associated with each other and stored as one record. In this specification, one record in the response history DB 28 is described as response history information. Of course, each information storage format in the response history DB 28 is not limited to the table format.

  Hereinafter, the response setting information 30 stored in the storage unit 20 will be described before describing the flow of the re-warning process. FIG. 6 shows an example of response setting information. The response setting described below is preset by the user.

  The image forming apparatus 10 displays a warning (re-warning) about the error condition when the current print job satisfies the error condition that has been satisfied in the past print job and allowed by the user. You can set whether or not to do. Whether or not the error condition satisfied by the current print job has been satisfied in the past is determined by referring to the response history DB 28.

  Further, in the image forming apparatus 10, when the current print job satisfies a certain error condition and performs a re-warning display, the response history information regarding the error condition stored in the response history DB 28 is displayed together with the re-warning display. You can set whether or not to do. For example, when a past print job satisfies the error condition, information on an error print instruction included in the past print job and information on whether or not the error condition in the past print job is acceptable Whether to display or not can be set.

  Further, the image forming apparatus 10 indicates the search range of the response history DB 28 when determining that the error condition satisfied in the current print job is the same as the error condition satisfied in the past print job. A response range can be set. For example, when the response range is set to “same user”, only the response history information of the same user name as the user name that input the current print job in the response history DB 28 is referred to in the determination. Among them, it is determined whether or not there is response history information related to the error condition satisfied by the current print job.

  In this embodiment, in addition to “same user”, “document name” or “keyword in record” can be selected as the response range. When the response range is set to “document name”, in the determination of whether or not the error condition satisfied in the current print job and the error condition satisfied in the past are the same, etc. Thus, only response history information having the same document name as that of the current print job is referred to. When the response range is set to “keyword in record”, the name of the user who input the current print job or the document name (keyword) of the current print job is stored in the record (response) from the response history DB 28. Only the response history information included in a part of the document name or the user name in the history information).

  Hereinafter, referring to FIG. 1 and FIG. 2 and FIG. 7, the processing flow of the image forming apparatus 10, in particular, the current print job satisfies the same error condition as the error condition satisfied by the past print job. A flow of processing (re-warning processing) in this case will be described.

  When an error print instruction is detected as a result of the print job being input to the image forming apparatus 10 and the preflight process being executed for the print job (steps S10 to S12 in FIG. 2), in step S14, the control unit 26 It is determined whether or not the error conditions satisfied by the user in the past are included among the error conditions satisfied by the current print job.

  In this processing, it is assumed that the table shown in FIG. 5 is stored as the response history DB 28, and the setting contents shown in FIG. 6 are stored as the response setting information 30. Furthermore, the user name of the user who has input the current print job is “brochure creation unit”, and the preflight check in step S10 detects an R91% print instruction and a 1-dot thin line print instruction in the print job. It shall be assumed. In other words, it is assumed that the current print job satisfies the error conditions of “R 90% or more” and “thin line 2 dots or less”.

  Since the response range in the response setting information 30 is “same user” and the user name of the user who has input the current print job is “brochure creation unit”, the control unit 26 first responds in the process of step S14. From the response history information included in the history DB 28, response history information whose user name is “brochure creation unit” is extracted. Next, in the extracted response history information, the response history information corresponding to the error condition “R90% or more” satisfied by the current print job, and the tolerance by the user is “Yes” Search for. As a result, the record R1 (see FIG. 5) is extracted from the response history DB 28. Further, the control unit 26 is response history information corresponding to the error condition of “two fine dots or less” satisfied by the current print job in the response history information extracted using the user name as a key, Search for response history information whose permission is “Yes”. As a result, the record R2 is extracted. Therefore, the control unit 26 determines that the error conditions satisfied by the user in the past are included in the error conditions satisfied by the current print job, and proceeds to S26 (FIG. 7).

  In step S <b> 26, the control unit 26 refers to the response setting information 30 and determines whether or not the re-warning display setting is set to “Yes”. First, a process when the re-warning display setting is set to “No” will be described. If the re-warning display setting is set to “NO”, the process proceeds to step S28.

  In step S28, the control unit 26 determines whether or not the current print job includes an error print instruction that satisfies an error condition that was not permitted in the past. Specifically, if the current print job satisfies a plurality of error conditions and at least one of the error conditions has never been permitted in the past, the process proceeds to step S30. In the present embodiment, the current print job includes a print instruction for a fine line of 1 dot, and there is response history information corresponding to the error condition of the error condition “2 dots or less of the fine line” in the response history DB 28. Since the permission from the user is “NO”, the process proceeds to step S30. If not, that is, if all of the error conditions satisfied in the current print job have been allowed in the past, the control unit 26 ends the preflight process without displaying a warning.

  In step S30, the control unit 26 displays a warning about an error condition that has been satisfied in the current print job and was not allowed in the past. In the present embodiment, referring to the response history DB 28, the error condition “R90% or more” has been permitted in the past, so the control unit 26 does not display a warning for a print instruction of R91%. On the other hand, since the error condition “2 dots or less for fine lines” has not been allowed in the past, the control unit 26 displays a warning about a print instruction for 1 line of fine lines.

  After step S30, the process proceeds to step S16 (FIG. 2), and thereafter the same processing as described above is performed. In this case, in step S22, a screen is displayed to ask the user whether or not to accept the error print instruction detected this time (in this embodiment, R91% print instruction and 1-dot thin line print instruction). Information indicating the print instruction and whether or not the user is allowed is stored in the response history DB 28.

  If the re-warning display setting is set to “YES” in step S26, the process proceeds to step S32. In step S32, the control unit 26 refers to the response setting information 30 and determines whether or not the response history display is set to “Yes”.

  If the response history display is set to “NO”, the process proceeds to step S34, and the control unit 26 displays a warning about the error print instruction detected in the current print job on the display unit 24. That is, a re-warning is also displayed for an error print instruction that satisfies an error condition allowed in the past. The warning text for the print instruction of R91% detected this time is, for example, “the image of R91% exists in the image of xcm × xcm arranged at the coordinates (xcm, xcm) of the x page”. .

  A warning is also displayed for an error print instruction included in the current print job that satisfies an error condition that has not been permitted in the past. In this embodiment, for example, in response to a print instruction for a thin line of 1 dot detected this time, there is a thin line of 1 dot with a length of xcm from the right at the coordinates (xcm, xcm) of the x page. "" Is displayed. A button for asking the user whether or not to allow sample printing is also displayed along with the warning.

  If the response history display is set to “YES”, the process proceeds to step S36, and the control unit 26 displays a warning similar to the warning displayed in step S34 on the display unit 24, and the current print job is satisfied. The past response history corresponding to the error condition is displayed.

  Specifically, based on the setting of the response range of the response setting information 30, the control unit 26 is first response history information included in the response history DB 28 and having a user name “brochure creation unit”. To extract. In the extracted response history information, all corresponding response history information is extracted for each error condition satisfied by the current print job. In this embodiment, the record R1 (see FIG. 5) is extracted for the error condition “R90% or more” included in the current print job (R91% as an error print instruction), and the error condition “thin line 2 dots or less” ( As an error print instruction, a record R2 is extracted for a fine line of 1 dot. When there are a plurality of response history information satisfying the above conditions in the response history DB 28, a plurality of response history information is extracted for each error condition. Then, the contents of the extracted response history information and the corresponding warning text are displayed. An example of such a display is shown in FIG.

  As shown in FIG. 8, response history information for the error condition “R90% or more” in the past is shown together with a warning indicating that the error condition “R90% or more” is satisfied. Specifically, “History: 2015/2015” is displayed immediately below the warning message “There is an image of R91% in the image of 10 cm × 10 cm arranged at the coordinates (5 cm, 5 cm) of the first page”. 03/17 10:00 “92% R92% is allowed in“ ABC brochure ”from the same user” is displayed. When a plurality of response history information corresponding to the error condition “R90% or more” is extracted in the response history DB 28, the contents of the extracted response history information are displayed.

  Similarly, a warning message and its response history are displayed for error conditions that have not been permitted in the past. Specifically, “History: 2015/03/17” immediately below the warning message “There is a 1-dot thin line with a length of 5 cm from the right in the coordinates (20 cm, 20 cm) of the first page”. 10:00 “2-dot thin line is rejected in the“ ABC brochure ”from the same user” is displayed.

  Thereafter, the process proceeds to step S16, and after step S16, the processing as described above is performed.

  The basic embodiment is as described above. Even if the current print job satisfies the error conditions allowed in the past, it is considered that it is relatively unlikely that this will greatly affect the print result. According to the present embodiment, the user can set the re-warning display to “No”. In such a setting, when the current print job satisfies an error condition allowed in the past, Since the warning is not displayed, it is possible to omit the confirmation work of the warning displayed after the preflight processing.

  In the present embodiment, a re-warning (that is, a warning when the current print job satisfies an error condition allowed in the past) can be displayed. This makes it possible to flexibly cope with the case where it is desired to confirm the print job more reliably, such as when high quality is required for the print result. Further, when a re-warning is displayed, a past response history for the error condition can be displayed. As a result, the user can refer to the response history for the error condition in the past when determining the process for the current print job.

  In addition, since the response range can be changed as appropriate, what kind of past response history is referred to can be changed according to the use environment of the user. For example, in the case of a usage environment in which the past response history for the same document name can be used as a reference when determining the action of the current print job rather than the past response history by the same user, the response range is set to “document It can be changed to "Name".

<First Modification>
When a re-warning is displayed to the user in step S34 or step S36 in the basic embodiment described above, an error print instruction (hereinafter referred to as “current error print instruction”) included in the current print job that satisfies a certain error condition. And the content of an error print instruction that satisfies the error condition in the past and allowed by the user (hereinafter referred to as “past error print instruction”). The warning content may be changed.

  More specifically, if the current error print instruction is a stricter condition than the past error print instruction, that is, if there is a greater difference between the contents of the print job and the print result, a warning that alerts the user is displayed. Otherwise, a normal warning is displayed.

  For example, it is assumed that an error printing instruction of R92% is included in a print job input in the past, and the user allows it. That is, it is assumed that the record R1 shown in FIG. 5 is stored in the response history DB 28.

  In this state, when a print job including an error print instruction of R91% is input, the control unit 26 compares “R91%” that is the current error print instruction and “R92%” that is the past error print instruction. In the case of R brightness, the greater the R brightness included in the print job, the greater the difference between the print job content and the print result. Therefore, “R91%”, which is the current error print instruction, is a condition that is less severe than “R92%”, which is the permitted past error print instruction. For example, a normal warning as shown in FIG. Is displayed.

  On the other hand, when a print job including an R95% print instruction is input, “R95%”, which is the current error print instruction, is stricter than “R92%”, which is the past error print instruction. As shown in (b), a warning content for prompting the user to pay attention is displayed. Specifically, the icon to be displayed is made larger and more conspicuous, or a warning message that prompts the user to pay attention is displayed.

  If the current error print instruction is less severe than the past error print instruction, it can be said that the current error print instruction is relatively likely to be allowed by the user. On the other hand, when the current error print instruction is a stricter condition than the past error print instruction, the current error print instruction is not necessarily permitted by the user. Therefore, it is possible to output a more suitable warning by changing the warning contents according to the contents of the current error printing instruction and the contents of the past error printing instruction.

<Second Modification>
In the basic embodiment and the first modification, whether to output a warning is determined based on a predetermined error condition (in the basic embodiment and the first modification, any of R, G, and B). In this case, it is determined based on a condition that a print instruction with a luminance of 90% or more is included, and a condition that a print instruction of a thin line with a thickness of 2 dots or less is included). The error condition may be dynamically changed based on the content of a certain past error printing instruction.

  For example, it is assumed that an error printing instruction of R92% is included in a print job input in the past, and the user allows it. That is, it is assumed that the record R1 shown in FIG. 5 is stored in the response history DB 28.

  In this state, when a print job including an error print instruction of R91% is input, in the determination of whether or not the current print job includes a print instruction that satisfies the error condition (particularly, determination regarding the luminance of R), From the response history DB 28, response history information relating to R, which is permitted by the user, is extracted. Then, from the extracted response history information, the one corresponding to the strictest error printing instruction is specified. That is, in the case of R, the response history information corresponding to the error print instruction having the largest luminance value of R is specified. An error condition is set based on the error print instruction included in the response history information specified as described above.

  In this example, since the record R1 is stored in the response history DB 28, the error condition for R is “R92% or more”. Therefore, the R91% print instruction included in the current print job is not determined to be an error print instruction. In other words, if no error print instruction is included, even if the current print job includes an R91% print instruction, it is determined that the current print job does not satisfy the error condition, and a warning is displayed. The preflight process ends.

  As mentioned above, although embodiment which concerns on this invention was described, this invention is not limited to the said embodiment, A various change is possible unless it deviates from the meaning of this invention.
