The print sheet is formed of a printing position alignment mark having a predetermined shape and having a predetermined area for performing alignment between print patterns in an offcut area of the print sheet by printing. The punching blade has a punching blade alignment mark of the same shape as the printing position alignment mark of the predetermined shape at a position corresponding to the printing position alignment mark. When the cut by the punching blade is correctly formed on the punched area of the print sheet, the punching blade alignment mark is formed in an overlapped state on the printing position alignment mark.

Description

  The present invention relates to an alignment mark of a punching blade with respect to a printed material for accurately punching an area to be punched of a printing sheet.

Conventionally, when an area to be punched is accurately punched by forming a cut in a printed matter, the cut is formed so as to be aligned with a cross mark, which is a printing alignment mark, and the positioning accuracy is managed.
However, even if a cut by a punching blade is formed in the alignment mark by printing, the cross mark itself is small, and since it is formed by ruled lines, it is difficult to see visually and sufficient positional accuracy management has not been performed.
On the other hand, there is provided a “reliable mark” in which a point for matching each step in the punching process is visually observed (see Patent Document 1).

JP 2009-107101 A

According to the “reliable mark” according to the invention of Patent Document 1, it is possible to easily perform alignment with the naked eye, to easily detect a defective product that occurs suddenly, and to adjust it at the manufacturing stage. The company will provide a safety mark that can be removed in the inspection process even if it is mixed in non-defective products. However, the invention of Patent Document 1 does not increase the punching position accuracy of printed matter.
An object of the present invention is to provide a punching blade alignment mark for accurately forming an incision in an area (periphery of a pattern to be punched) of a printing sheet in order to accurately punch an area to be punched of a printing sheet. To do.

In order to achieve the above object, the first aspect of the punching blade alignment mark of the present invention is:
This is a punching blade alignment mark that aligns the punched blade with the punched blade area when the printed sheet is punched with a punching device. The printed sheet is printed within the print sheet trimming area. A printing alignment mark having a predetermined area and a predetermined shape for positioning the symbols is formed by printing, and the punching blade is positioned at a position corresponding to the printing alignment mark. The punching blade alignment mark has the same shape as the printing alignment mark of the shape, and the cutting blade alignment mark is printed when the cut by the punching blade is correctly formed in the punched area of the printing sheet. It is characterized by being formed in a state where it overlaps with the alignment mark.

  The second aspect is the first aspect, wherein the printing sheet is a single-layer paper base, and the cut formed in the area where the printing sheet is punched is formed in a state of penetrating the paper base. The blade alignment mark is formed so as not to penetrate the printing sheet.

  The third aspect is the first aspect, wherein the printing sheet is a three-layer paper comprising a paper substrate, an adhesive layer or a pseudo-adhesive layer, and a release substrate, and printing is performed on the exposed surface of the paper substrate. In addition, the cut formed in the area where the printing sheet is punched (around the pattern to be punched) is formed in a state of penetrating the paper and the pressure-sensitive adhesive layer or the pseudo adhesive layer.

1) A punching blade alignment mark for aligning a punching blade with an area to be punched when a printing sheet is punched by a punching device, like the punching blade alignment mark of the present invention. In the printing sheet, a printing alignment mark having a predetermined area and a predetermined shape is formed by printing in order to align the printed symbols within the cut-off area of the printing sheet. A punching blade alignment mark having the same shape as the printing alignment mark of the predetermined shape is provided at a position corresponding to the printing alignment mark, and the incision by the punching blade is correctly formed in the area to be punched of the printing sheet. When the punching blade alignment mark is formed, the punching blade alignment mark is formed so as to overlap the print alignment mark. , Punching blade alignment mark itself is liable alignment is seen by "having a predetermined has an area predetermined shape", also became clarity when bending etc. occurred.
2) Also, the printing sheet is a single-layer paper substrate, and the cut formed in the area where the printing sheet is punched is formed so as to penetrate the paper substrate, and the punching blade alignment mark does not penetrate the printing sheet. In addition, the printing sheet is a three-layer paper composed of a paper substrate, an adhesive layer or a pseudo-adhesive layer, and a release substrate, and printing is performed on the exposed surface of the paper substrate. The cuts formed in the area to be punched out (around the pattern to be punched out) should be formed through the paper and the adhesive layer or pseudo-adhesive layer. The punching blade alignment mark remains on the printed sheet. Even after the area to be removed is “detached” from the print sheet, the positional accuracy of “cut” can be confirmed as necessary.

It is a figure for demonstrating an example of the punching blade position alignment mark of this embodiment. It is a figure for demonstrating other examples of the punching blade alignment mark of this embodiment. It is a figure for demonstrating the punching die which punches out the printing sheet of FIG. It is a figure for demonstrating an example of the punching blade position alignment mark of this embodiment. It is a figure for demonstrating the AA line cross section of FIG.

With reference to FIG. 1, an example of the punching blade alignment mark of this embodiment is demonstrated.
FIG. 1 shows a “symbol 2 printed in an area to be punched” in which a flower symbol is printed on the exposed surface of the printing sheet 1 and the inside is punched by a punching blade from the boundary of the flower symbol.
A cut 7 of an area to be punched is formed at the boundary portion of the pattern 2 printed in the punched area, which is punched by the punching blade.

In addition, a print alignment mark 5 for aligning the print symbols is formed by printing in a cut area of the print sheet surrounded by the trimming finish mark 6 and the outer periphery of the print sheet 1.
As shown in enlarged view in FIG. 4A, the print alignment mark 5 is a cross mark 51 of the print alignment mark and a punching blade of the print alignment mark having a predetermined area and a predetermined shape. An alignment mark (a square print alignment mark with four corners) is printed. A punching blade alignment mark 71 is formed by cutting so as to overlap (cut into) the alignment mark 52 with the punching blade of the printing alignment mark.

FIG. 3 is a plan view of a punching die for punching the printing sheet of FIG.
In the punching die 800, the alignment mark 52 (print alignment mark having a predetermined shape) with the punching blade of the above-described print alignment mark is located at a position corresponding to the print alignment mark 5 of the printing sheet 1 shown in FIG. The punching blade 81 having the same shape as the punching blade alignment mark is formed on the lower left and right sides of the punching die 800.
The punching blade 81 of the punching blade alignment mark is used to align the cut finish mark 6 of the printing sheet 1 shown in FIG. 1 and the cutting pattern area of the printing sheet surrounded by the outer periphery of the printing sheet 1, and the printing patterns in the printing pattern. This corresponds to the print alignment mark 5 for performing.

  In FIGS. 1 and 3, when the cut 7 in the area to be punched by the punching blade 8 in the area to be punched in the punching die 800 is correctly formed with respect to the pattern 2 printed in the area to be punched in the printing sheet 1, punching is performed. The blade alignment mark 71 is formed so as to overlap the print alignment mark 5 (so as to bite into the ruled line of the printed print alignment mark 5).

FIG. 2 is another example of the punching blade alignment mark of the present embodiment.
The example of “the pattern 4 printed in the area to be punched” printed on the printing sheet 10 shown in FIG. 2 is used for, for example, a product number attached to the product and used as a sticker attached to the product. . As shown in FIG. 2, there is no one with the same number, and when a defect is found in the product and an inquiry is made, it becomes an important number for tracking which product the lot is.
A frame 40 is displayed outside the “design 4 printed in the area to be punched out”, but such “design 4 printed in the area to be punched out” is required to have the highest punching accuracy.

For example, if the notch 7 of the area to be punched is shifted 0.5 mm downward from the position where it should be correctly formed, the upper and lower margins of the seal frame 40 cut by the notch 7 of the area to be punched are 0.5 mm on the upper side. Narrow and the bottom is finished 1mm wider.
In this way, when the quality of the seal overlaps with the quality of the defective product, the quality of the product is evaluated to be equivalent to the quality of the seal, and the punching accuracy by the punching die is an important quality control factor. .
Although not shown, a keyboard panel used for a calculator or the like requires a high degree of punching accuracy, and the punching blade alignment mark of the present invention is preferably used.

With reference to FIG. 4, an example of the punching blade alignment mark of the present embodiment will be described.
The print alignment mark 5 shown in FIG. 4A is a print alignment mark having a square shape with a four-corner round corner “having a predetermined area and a predetermined shape” as a cross mark 51 of the print alignment mark. . The alignment mark 52 with the punching blade of the square-shaped printing alignment mark with the four corner round corners surrounding the cross mark 51 of the printing alignment mark is the punching blade alignment mark 71 by the punching die shown in FIG. It has a corresponding shape. FIG. 4B shows the printing alignment of the pattern in which the cross mark 51b of the printing alignment mark in FIG. 4A protrudes outside the alignment mark 52 with the punching blade of the square printing alignment mark. This is the mark 5b.

  The above-described print alignment marks 5 and 5b are conveniently positioned with a large alignment mark for visual alignment, but are surrounded by the cutting finish mark described in FIG. It is assumed that it fits in the bleed area. Therefore, the size of the alignment mark 52 with the punching blade of the printing alignment mark is about 10 mm on the narrow side. When formed so as to extend over one side of the print sheet, the long side can be extended to about 10 to 30 mm. Further, the alignment mark 52 with the punching blade of the printing alignment mark is not limited to a square and a rectangle, and may have any shape as long as it fits within a trimming area surrounded by the cut finish mark and the outer periphery of the printing sheet 1.

With reference to FIG. 5, the AA line cross section of FIG. 1 is demonstrated.
The example shown in FIG. 5 is an example of a three-layer paper in which the base material of the printing sheet 1 is sequentially laminated from the upper surface, although not shown, a paper base material, an adhesive layer or a pseudo adhesive layer, and a release base material.
The character 3 and the pattern 2 printed on the area to be punched are printed on the exposed surface of the paper substrate, and the notch 7 of the area to be punched formed on the area to be punched on the printed sheet is the paper and the adhesive layer or pseudo-adhesion It is formed in a state of penetrating the agent layer.
Similarly, the punching blade alignment mark 71 is formed in a state of penetrating the paper and the adhesive layer or the pseudo adhesive layer.

The punching die will be described.
The punching die is prepared according to the punching device. For example, in the case of punching with a cylinder, a flexible punching blade is stuck around the cylinder to produce a punching die. In recent years, a punching blade is produced by etching according to a punching pattern (design printed on an area to be punched) on the surface layer of a cylinder to form a punching die. The punching blade by the latter etching can not only obtain the accuracy of the height of the blade, but also can punch a fine pattern.
The punching blade by the cylinder can cope with a sheet-like printed matter by using a sheet-fed rotary printing apparatus.
On the other hand, there is a case in which a groove is formed in a flat plate-shaped substrate, and a punching blade is formed by fitting a flexible strip-shaped punching blade (see, for example, FIG. 3). Such a punching apparatus can suitably cope with a printing sheet having a relatively thick substrate, but is not suitable for punching the fine pattern.

  This can be used as a mark for aligning a punching blade with respect to a printed material for accurately punching an area where a printing sheet is punched.
