Image forming apparatus
A print image generation unit is configured to perform a first rasterization process for printing and thereby generate print image data, and perform a second rasterization process for inspection and thereby generate reference image data, on the basis of a print request. A print unit is configured to perform printing based on the print image data onto a print paper sheet and thereby produce a print product. An image scanning unit is configured to perform image scanning of the print product and thereby generate scan image data. An inspection processing unit is configured to compare the scan image data and the reference image data and thereby perform inspection of the printed matter. Further, the second rasterization process is a rasterization process performed in a rendering condition different from a rendering condition of the first rasterization process.
1. An image forming apparatus, comprising:
a print image generation unit configured to perform a first rasterization process for printing and thereby generate print image data and perform a second rasterization process for inspection and thereby generate reference image data, on the basis of a print request; wherein the first and second rasterization processes are performed on image information from the print request;
a print unit configured to perform printing based on the print image data onto a print paper sheet and thereby produce a print product;
an image scanning unit configured to perform image scanning of the print product and thereby generate scan image data; and
an inspection processing unit configured to compare the scan image data and the reference image data and thereby perform inspection of the printed matter;
wherein the second rasterization process is a rasterization process performed in a rendering condition different from a rendering condition of the first rasterization process.
2. The image forming apparatus according to claim 1 , wherein the rendering condition includes at least one of resolution, color space after color conversion, and color adjustment characteristic.
3. The image forming apparatus according to claim 1 , wherein the second rasterization process is performed on the basis of a chromogenic characteristic of colorant on the print paper sheet.
4. The image forming apparatus according to claim 1 , wherein the second rasterization process is performed on the basis of a color temperature the print paper sheet.
5. The image forming apparatus according to claim 1 , wherein the inspection of the printed matter comprises inspection process generating a difference between the scan image data and the reference image data for each pixel position.
