no. 1 approach

[0051] In view of this, in the first embodiment, on the premise that marks such as trimming marks that do not pose a problem with image quality degradation are formed on the outside of major images such as text, photographs, and drawings that cause image quality degradation to be a problem, That is, the first image including the main image is formed in the image area, and the second image including marks such as crop marks is formed in the non-image area outside the image area, then for at least the surface of the recording paper, the image area (first image) It is formed on the recording paper without scaling, and the non-image area (second image) is formed on the recording paper with scaling. Therefore, the first image is not scaled and its image quality does not deteriorate. In addition, since the second image is scaled, its image quality is degraded, but by compensating for the position shift of the second image on the surface of the recording paper, etc., by scaling corre...

no. 2 approach

[0105] The second embodiment of the present invention is the same as the above-mentioned first embodiment in that it is applied to figure 1 image forming apparatus 1, and has figure 2 Although the control system is as shown, the image formed on the front and back of the recording paper P is different from that of the above-mentioned first embodiment.

[0106] In the above-mentioned first embodiment, the surface image Ga is composed of the main first image (text, photo, drawing, etc.) ga1 and the second image ga2 including the mark Ma for cutting. (text, photo, drawing, etc.) gb1 and the second image gb2 including the mark Mb for cropping are constituted. Therefore, the front image Ga and the back image Gb are images actually printed on the front and back of the recording paper P. As shown in FIG.

[0107] In contrast, in the second embodiment, both the front and back of the recording paper P are printed to form Figure 11 Adjust pattern J as shown. The adjustment pattern ...

Abstract

The present invention relates to an image forming apparatus, an image forming system, and an image forming method. The image forming apparatus forms a first image on an image area of ​​a paper, and forms a second image on a non-image area outside the image area of ​​the paper. a magnification setting unit that determines the magnification of the second image; and forming the first image on the image area of ​​the paper without scaling, and scaling the second image and the non-image area at the magnification set by the magnification setting unit. Formed on the image forming part of the paper.

Description

[0001] This application claims priority based on Japanese Patent Application No. 2014-041458 filed on March 4, 2014, the entire content of which is incorporated herein. technical field [0002] The present invention relates to an image forming apparatus, an image forming system, and an image forming method that form an image by printing on paper. Background technique [0003] As such an image forming apparatus, there is an image forming apparatus that forms an image on the surface of a sheet and then forms an image on the back of the same sheet, but there is a problem that when the image forming process is performed on the surface (front) of the sheet, the sheet expands and contracts, causing the sheet to The image forming position on the surface of the paper is deviated from the image forming position on the back side of the paper. [0004] Therefore, in Japanese Patent Application Laid-Open No. 2007-206667 (hereinafter referred to as Patent Document 1), when an image is fo...
