Description

  The present invention relates to an image data creation apparatus that creates image data for performing foil stamping, and an image forming apparatus that prints a document based on the image data.

  A document or the like to which a foil is applied by using an image forming apparatus such as a printer is generally performed in the following procedure. (1) A foil pressing object is printed on a sheet by using a toner (hereinafter also referred to as a foil pressing toner) used as a paste when pressing the foil. (2) Using a foil press, the paper is heated to melt the foil-pressing toner used for the printing, and the foil is pressed against the paper. (3) The portion of the foil that has not been pressure-bonded to the paper is wound up with a roller or the like, so that the foil is applied to the portion printed using the foil pressing toner. (4) Normal printing such as color printing or monochrome printing is performed on the sheet on which the foil has been applied.

  When a document or the like is created by such a procedure, when normal printing is performed on a paper sheet with a foil, a portion provided with the foil and an object printed by the normal printing (hereinafter referred to as a normal object) Misalignment may occur between the two. In particular, when the portion to which the foil is applied and the normal object are in contact with each other, this displacement causes white spots between the portion to which the foil is applied and the normal object (a phenomenon in which the background color of the paper can be seen). Will occur.

  For example, Patent Document 1 discloses the following foil pressing process. First, an image (negative image) obtained by inverting a portion to be foil pressed (positive image) is printed first, and foil pressing is performed on this negative image. Thereafter, the foil sheet on which the negative image portion of the foil is peeled off by foil pressing on the negative image is used to enlarge and print the positive image on the printed paper. As a result, the foil transfer process can be performed with high accuracy even when the paper position or a predetermined positive image is displaced.

  In this printing system 5C, the foil stamping machine 50C has the same configuration as the foil stamping machine 50A of the printing system 5A and the foil stamping machine 50B of the printing system 5B. 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 for creating a document with a foil in the printing systems 5A, 5B, and 5C (hereinafter collectively referred to as the printing system 5) will be described.

  FIG. 5 is a flowchart illustrating a method for creating a document with a foil in the printing system 5.

  First, when the print 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 print job. The rasterizing process is performed on the foil pressing object data, and the foil pressing object to be printed is specified from the page data created by the rasterizing process (step S001).

  The CPU 11 further rasterizes the normal object data included in the print job, and specifies a normal object to be printed from the page data created by the rasterization process. Then, the CPU 11 determines whether or not at least a part of the normal object exists around 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 there is no normal object around the foil pressing object (step S002; No), the CPU 11 instructs the printing unit 16 to print the foil pressing object (step S003). Then, the foil stamping machine 50A, 50B or 50C (hereinafter collectively referred to as the foil stamping machine 50) performs the foil stamping on the portion where 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 based on the image data of the normal object generated by the CPU 11 of the second image forming apparatus in step S004. The normal object is printed on the sheet on which the foil has been applied (step S005). Then, this process ends.

  On the other hand, if 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 color information of the normal object is obtained from the image data of the normal object. Obtaining and specifying the color of the normal object around the foil pressing object (step S006).

  Then, the CPU 11 determines the first toner amount used for printing the normal object around the foil pressing object to be performed simultaneously with the printing of the foil pressing object from the color of the normal object specified in step S006. (Step S007).

  At this time, the CPU 11 does not attach the first toner to the printing position of the normal object when the foil is pressed (to the extent that the toner used for printing the normal object does not function as glue due to heating of the paper when pressing the foil). The amount needs to be determined. Further, the amount of heat absorbed by the toner differs depending on the color of the toner (in general, the higher the proportion of K (black) toner, the higher the amount of heat absorbed), so the CPU 11 is identified in step S006. The first toner amount is determined according to the color of the normal object.

  Further, it is preferable that the first toner amount be 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 pressing object as described above.

  Further, the CPU 11 performs the normal operation around the foil pressing object to be performed simultaneously with the printing of the foil pressing object based on the first toner amount determined in step S007 and the color of the normal object to be printed. A screen pattern used for printing the object is determined (step S008). For example, an error diffusion screen is used as the screen pattern.

  The CPU 11 generates image data of the foil pressing object specified in step S001. When the image data of the foil pressing object is generated, the printing of the foil pressing object is set to solid printing, and the color of the toner used for printing of the foil pressing object is set to K color. Further, the CPU 11 determines, based on the normal object identified in step S002, the first toner amount determined in step S007, and the screen pattern determined in step S008, the image of the normal object around the foil pressing object. Data is generated (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 simultaneously print the foil pressing object and the normal object around the foil pressing object on the sheet based on the image data generated in step S009. Based on the image data, the printing unit 16 simultaneously prints the foil pressing object and the normal object around the foil pressing object (step S010).

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

  FIG. 7 is an explanatory diagram illustrating an example of a sheet on which foil pressing has been performed. 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.

  Thereafter, 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 pressing object (step S012).

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

  At this time, the first toner amount acquired in step S012 is set to 50% during solid printing, and the final toner amount of the normal object around the foil pressing object after additional printing is set to 80% during solid printing. If it is, the CPU 11 determines the second toner amount as 30% of the 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 pressing object after the reprint printing. For example, the reprint image screen pattern is determined so that the cycle does not overlap with the screen pattern acquired in step S012.

  The CPU 11 generates image data of normal objects other than the normal object around the foil pressing 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 performs the foil stamping 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 reprint of a normal object around the object is generated (step S014).

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

  Then, the CPU 11 instructs the printing unit 16 to simultaneously print the normal object around the foil pressing object and the other normal objects on the sheet based on the image data generated in step S014. Based on the image data, the printing unit 16 performs overprint printing of the normal objects around the foil stamping object and normal printing of other normal objects (step S015).

  FIG. 9 is an explanatory diagram illustrating an example of a final document output after printing a normal object. The normal object around the foil stamping object is printed without any particular change compared to the other normal objects.

  Further, in the method shown in the flowchart of FIG. 5, when the normal object is overprinted around the foil pressing object, the overprinted normal object and the foil pressing object (the portion to which the foil has been printed) printed in step S010. Even if a misalignment occurs, a 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 normal object printing and follow-up printing around the foil pressing object will be described.

  FIG. 10 is a diagram illustrating a case where a normal object is printed and overprinted in a state where the first toner amount and the second toner amount are uniform (no toner amount gradation) around the foil pressing object. FIG. When the normal object is printed with a uniform first toner amount around the foil pressing object in step S010 in FIG. 5, the normal object is printed with a uniform second toner amount around the foil pressing object in step S015. Reprinted.

  For example, if the final toner amount of the normal object in the periphery of the foil stamping object after the additional printing is set to 80% of the solid printing, the first object of 50% of the normal object uniformly printed in step S010. When printing is performed with the toner amount, the normal object is overprinted with a uniform second toner amount of 30% of the solid printing around the foil pressing object.

  At this time, if a positional deviation occurs between the normal object printed in step S010 and the normal object printed in step S015, the location where the normal object is printed in step S010 and the location where the normal object is printed in step S010 are displayed. The boundary between them becomes conspicuous. In the example of FIG. 10, portions printed with the toner amounts of 50%, 80%, and 30% at the time of solid printing are generated, and the boundary between the respective portions becomes conspicuous.

  Therefore, first, the CPU 11 of the first image forming apparatus determines the first toner amount having a gradation that gradually decreases from the foil pressing object toward the outer edge of the peripheral area. 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 overprinted with a first toner amount having 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 printed in step S015, the normal object is printed in step S010 and the location where the overprinting was performed. The border with the place becomes inconspicuous.

  The embodiment of the present invention has been described with reference to the drawings. However, the specific configuration is not limited to that shown in the embodiment, and there are changes and additions within the scope of the present invention. Are 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 based on the color information of the normal object as the first toner amount determination unit 34. However, the CPU 11 of the first image forming apparatus determines the first toner amount so that the foil does not adhere to the printing position of the normal object around the foil pressing object when the foil pressing is performed on the printing position of the foil pressing object. For example, the first toner amount may be set to a predetermined numerical 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 determination unit 34 so as to gradually decrease from the foil pressing object toward the outer edge of the peripheral area. Determined the gradation. 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 area. Further, the CPU 11 of the first image forming apparatus determines the gradation of the first toner so that the first toner amount changes in a predetermined direction other than the direction from the foil pressing object toward the outer edge of the peripheral area. Also good.

  In this embodiment, the foil stamping object and the normal object are printed on the paper. However, the recording medium to be printed may be a printable material such as cloth, plastic, or wood.

  The present invention may be a program that causes an information processing apparatus to function as an image data creation apparatus.
