Description

The present invention relates to an image data creating device that creates image data for foil stamping and an image forming device that prints a document based on the image data.

Creating a document or the like to which foil is applied by using an image forming apparatus such as a printer is generally performed by the following procedure. (1) A foil stamping object is printed on paper using a toner used as glue during foil stamping (hereinafter, also referred to as a foil stamping toner). (2) By heating the paper with a foil stamping machine, the foil stamping toner used for the above printing is melted and the foil is pressed against the paper. (3) By winding the foil of the portion not crimped on the paper with a roller or the like, the foil is applied to the portion printed using the toner for stamping the foil. (4) Normal printing such as color printing or monochrome printing is performed on the foiled paper.

When a document or the like is created by such a procedure, when normal printing is performed on foiled paper, the foiled part and the object printed by normal printing (hereinafter referred to as a normal object) Misalignment may occur between them. In particular, when the part to be foiled and the normal object are in contact with each other, due to this misalignment, white spots (a phenomenon in which the color of the background of the paper is visible) occur between the part to be foiled and the normal object. It will occur.

For example, Patent Document 1 discloses the following foil stamping process. First, an image (negative image) in which the portion to be stamped (positive image) is inverted is printed first, and the negative image is stamped with foil. Then, using a foil sheet from which the foil of the negative image portion has been peeled off by foil stamping on the negative image, the positive image is enlarged and printed on the paper. As a result, the foil transfer process can be performed with high accuracy even when the position of the paper or the position of a predetermined positive image is displaced.

Further, the image forming apparatus 10D has the same configuration as the image forming apparatus 10B of the printing system 5B, and the image forming apparatus 10E has the same configuration as the image forming apparatus 10C of the printing system 5B.

Next, a method of creating a foiled document in the printing system 5A, 5B, 5C (hereinafter, collectively referred to as the printing system 5) will be described.

FIG. 5 is a flowchart showing a method of creating a foiled document in the printing system 5.

First, when the printing system 5 receives a print job from a client PC or the like, the CPU 11 of the image forming apparatus 10A, 10B or 10D (hereinafter collectively referred to as a first image forming apparatus) is included in the printing job. The foil stamping object data is subjected to rasterization processing, and the foil stamping object to be printed is specified from the page data created by the rasterization processing (step S001).

The CPU 11 further performs rasterization processing on the normal object data included in the print job, and identifies the normal object to be printed from the page data created by the rasterization processing. Then, the CPU 11 determines whether or not at least a part of the normal object exists in the periphery of the foil pressing object (for example, within 5 pixels from the outer edge of the foil pressing object) (step S002).

When the CPU 11 determines that the normal object does not exist around the foil stamping object (step S002; No), the CPU 11 instructs the printing unit 16 to print the foil stamping object (step S003). Then, the foil stamping machine 50A, 50B or 50C (hereinafter, collectively referred to as the foil stamping machine 50) presses the foil on the portion on which the foil stamping object is printed (step S004). Further, the image processing apparatus 10A, 10C or 10E (hereinafter collectively referred to as a second image forming apparatus) is in step S004 based on the image data of the normal object generated by the CPU 11 of the second image forming apparatus. A normal object is printed on foiled paper (step S005). Then, this process ends.

On the other hand, when the CPU 11 of the first image forming apparatus determines that at least a part of the normal object exists around the foil pressing object (step S002; Yes), the CPU 11 of the normal object obtains the color information of the normal object from the image data of the normal object. It is acquired and the color of the normal object around the foil pressing object is specified (step S006).

Then, the CPU 11 determines the amount of the first toner used for printing the normal object around the foil pressing object, which should be performed at the same time as printing the foil pressing object, from the color of the normal object specified in step S006. (Step S007).

At this time, the CPU 11 uses the first toner to the extent that the foil does not adhere to the printed portion of the normal object during foil stamping (the toner used for printing the normal object does not function as glue due to the heating of the paper during foil stamping). The amount needs to be determined. Further, since the amount of heat absorbed by the toner differs depending on the color of the toner (generally, the higher the proportion of the K (black) color toner, the higher the amount of heat absorbed), the CPU 11 is specified in step S006. Normally, the first toner amount is determined according to the color of the object.

Further, it is preferable that the amount of the first toner is at least such that the user or the like can recognize the contents of the normal object by printing the normal object around the foil stamping object as described above.

Further, the CPU 11 is based on the first toner amount determined in step S007, the color of the normal object to be printed, and the like, and the CPU 11 performs the normal operation around the foil pressing object to be performed at the same time as printing the foil pressing object. The screen pattern used to print the object is determined (step S008). As this screen pattern, for example, an error diffusion screen or the like is used.

The CPU 11 generates image data of the foil pressing object specified in step S001. When the image data of the foil stamping object is generated, the printing of the foil stamping object is set to solid printing, and the color of the toner used for printing the foil stamping object is set to K color. Further, the CPU 11 has an image of the normal object around the foil pressing object based on the normal object specified in step S002, the first toner amount determined in step S007, and the screen pattern determined in step S008. Generate data (step S009).

FIG. 6 is an explanatory diagram showing an example of the image data of the foil pressing object generated in step S009 and the image data of the normal object around the foil pressing object. As shown in FIG. 6, only the image data of the foil pressing object and the image data of the normal object around the foil pressing object are integrally generated.

Then, the CPU 11 instructs the printing unit 16 to print the foil stamping object and the normal object around the foil stamping object on the paper at the same time based on the image data generated in step S009. Based on this image data, the printing unit 16 prints the foil stamping object and the normal object around the foil stamping object at the same time (step S010).

When the printing of the foil stamping object and the normal object around the foil stamping object is completed, the foil stamping machine 50 stamps the paper on which the foil stamping object or the like is printed (step S011).

FIG. 7 is an explanatory diagram showing an example of paper that has been foil-pressed. As shown in FIG. 7, in the foil stamping machine 50, the foil is applied to the portion where the foil stamping object is printed, but the foil does not adhere to the normal object printed around the foil stamping object.

After that, in the second image forming apparatus, the CPU 11 of the second image forming apparatus acquires the first toner amount and the screen pattern used for printing the normal object around the foil stamping object (step S012).

Then, the CPU 11 determines the second toner amount to be used for the reprinting of the normal object around the foil pressing object and the reprint image of the normal object based on the first toner amount and the screen pattern acquired in step S012. The screen pattern is determined (step S013).

At this time, the first toner amount acquired in step S012 is set to 50% at the time of solid printing, and the final toner amount of the normal object around the foil stamping object after reprint printing is set to 80% at the time of solid printing. If so, the CPU 11 determines that the amount of the second toner is 30% of that at the time of solid printing.

Further, when determining the reprint image screen pattern of the normal object, the CPU 11 determines the reprint image screen pattern so that moire does not occur in the normal object around the foil stamping object after the reprint print. For example, the reprint image screen pattern is determined so that the period does not overlap with the screen pattern acquired in step S012.

The CPU 11 generates image data of a normal object other than the normal object around the foil stamping object based on the normal object specified in step S002 or the normal object specified by the second image forming apparatus. Further, the CPU 11 is used for foil pressing based on the normal object specified in step S002 or the normal object specified by the second image forming apparatus, the second toner amount determined in step S013, and the reprint image screen pattern. Image data for reprinting a normal object around the object is generated (step S014).

FIG. 8 is an explanatory diagram showing an example of image data for reprinting a normal object around the foil pressing object generated in step S014 and image data of other normal objects. As shown in FIG. 8, image data of a normal object to be normally printed is generated, but for a portion to be reprinted, the toner amount should be reduced by the amount of the first toner used in step S010. Image data is generated in.

Then, the CPU 11 instructs the printing unit 16 to print the normal object around the foil stamping object and the other normal objects at the same time on the paper based on the image data generated in step S014. Based on this image data, the printing unit 16 prints the normal objects around the foil stamping object by additional printing, and prints the other normal objects normally (step S015).

FIG. 9 is an explanatory diagram showing an example of a final document that is usually output after printing the object. The normal objects around the foil stamping object are printed in the same manner as the other normal objects.

Further, in the method shown in the flowchart of FIG. 5, when the normal object is reprinted around the foil stamping object, the reprinted normal object and the foil stamping object (foiled portion) printed in step S010 are used. Even if there is a misalignment between the foil stamping objects, the normal object is printed around the foil stamping object at the same time as the foil stamping object is printed. Can be prevented.

Next, the gradation of the first toner amount and the second toner amount used for printing the normal object and the follow-up printing around the foil stamping object will be described.

FIG. 10 shows a case where a normal object is printed and reprinted in a state where the first toner amount and the second toner amount are uniform (without a gradation of the toner amount) around the foil pressing object. It is a figure. When the normal object is printed with a uniform first toner amount around the foil stamping object in step S010 of FIG. 5, in step S015, the normal object is printed with a uniform second toner amount around the foil stamping object. It is reprinted.

For example, when the final toner amount of the normal object around the foil stamping object after reprint printing is set to 80% at the time of solid printing, in step S010, the normal object is uniformly set to 50% at the time of solid printing. When printed with a toner amount, the normal object is reprinted around the foil stamping object with a uniform second toner amount of 30% of that at the time of solid printing.

At this time, if a misalignment occurs between the normal object printed in step S010 and the normal object reprinted in step S015, the reprinted part and the part where the normal object is printed in step S010 The boundary between them stands out. In the example of FIG. 10, the portions printed with the toner amounts of 50%, 80%, and 30% of the solid printing are generated, and the boundaries of the respective portions are conspicuous.

Therefore, first, the CPU 11 of the first image forming apparatus determines the amount of the first toner having a gradation that gradually decreases from the foil pressing object toward the outer edge of the peripheral region thereof. Next, the CPU 11 of the second image forming apparatus determines the second toner amount having a gradation that cancels the gradation of the first toner amount based on the first toner amount.

FIG. 11 is an explanatory diagram showing a case where a normal object is printed and reprinted with a first toner amount having a gradation and a second toner amount having a gradation that cancels the gradation of the first toner amount.

In this case, even if a misalignment occurs between the normal object printed in step S010 and the normal object reprinted in step S015, the reprinted portion and the normal object are printed in step S010. The boundary with the part becomes inconspicuous.

Although the embodiment of the present invention has been described above with reference to the drawings, the specific configuration is not limited to that shown in the embodiment, and there are changes and additions within the range not departing from the gist of the present invention. Is also included in the present invention.

In the printing system 5 according to the present embodiment, the CPU 11 of the first image forming apparatus determines the first toner amount as the first toner amount determining unit 34 based on the color information of the normal object. However, the CPU 11 of the first image forming apparatus determines the amount of the first toner so that the foil does not adhere to the printed portion of the normal object around the foil stamping object when the foil stamping is performed on the printed portion of the foil stamping object. For example, the first toner amount may be set to a predetermined value derived from an experiment or the like regardless of the color of the normal object.

In the printing system 5 according to the present embodiment, the CPU 11 of the first image forming apparatus serves as the first toner amount determining unit 34 of the first toner so as to gradually decrease from the foil stamping object toward the outer edge of the peripheral region thereof. I decided the gradation of. However, the CPU 11 of the first image forming apparatus may determine the gradation of the first toner so as to gradually increase from the foil pressing object toward the outer edge of the peripheral region thereof. Further, the CPU 11 of the first image forming apparatus determines the gradation of the first toner so that the amount of the first toner changes in a predetermined direction other than the direction from the foil pressing object toward the outer edge of the peripheral region thereof. May be good.

Further, in the present embodiment, the foil stamping object and the normal object are printed on the paper, but the recording medium to be printed may be a printable medium such as cloth, plastic, or wood.

Further, the present invention may be a program that causes an information processing device to function as an image data creating device.
