An image forming system includes a computer and an image forming apparatus. The computer includes a print data generating circuit to generate print data of an image. The image forming apparatus includes a rendering circuit to execute rendering of the image based on the print data. The computer includes an image generating circuit generates an image object to indicate a state where the objects are overlapped in the image with a reduced resolution at least partially. The print data generating circuit generates the print data including the at least one object included in the image and the image object generated by the image generating circuit. When the rendering circuit processes the image object, the rendering circuit enhances the resolution of a part corresponding to the object in the image object based on a shape of the object overlapped at upper side in the image object.

In a host computer, a print processor generates, in a drawing region of a memory device context, additional raster data for drawing an additional drawing in addition to drawing information regarding a logical page included in an Enhanced Metafile Format (EMF) spool file, and a graphics driver (GD) module of a printer driver combines document raster data generated in a drawing region of a printer device context with the additional raster data, and generates print data based on post-combination raster data.

An image processing device and an image processing method are provided. The image processing device includes: a generation unit that generates foil transfer data representing an ejection region of the adhesive ink in a predetermined color with respect to image data indicating an image to be printed on the recording medium; and a composition unit that composes the foil transfer data and the image data to generate composite image data, in which when printing is performed on the recording medium, the adhesive ink is ejected to the region of the predetermined color in the composite image data. The image processing method includes: a first step of generating the foil transfer data; a second step of generating the composite image data; and a third step of ejecting the adhesive ink to a region of a predetermined color in the composite image data and transferring the foil to the recording medium.

An image forming apparatus according to the present disclosure stores image data of an image having a plurality of regions, the plurality of regions having stepwise different densities, including a first region, a second region, and a third region between the first region and the second region, and satisfying a relationship of a moisture amount in the first region<a moisture amount in the third region<a moisture amount in the second region, and forms the stored image data on a print medium.

An image forming apparatus includes: a forming unit configured to form an image on a sheet by forming a plurality of toner images using a plurality of types of toner, and transfer the plurality of toner images onto the sheet, or transfer the plurality of toner images onto the sheet via an intermediate transfer member; and a controller configured to control the forming unit to form a formed image and an antimicrobial pattern on the sheet based on first image data representing the formed image, wherein at least one first toner out of the plurality of types of toner is antimicrobial toner that includes an antimicrobial agent, at least one second toner out of the plurality of types of toner is non-antimicrobial toner that does not contain the antimicrobial agent, and the antimicrobial pattern is formed using the first toner.

A program causes a controller to generate print data and to perform input processing, plate data generation processing, and print data generation processing. The data input processing includes inputting, as input data for performing inserting-component printing, non-variable data corresponding to a shared portion and variable data indicating a variable portion. The plate data generation processing includes plate data for color layer generation processing for generating a plate data for color layer associated with a color layer and plate data for single-color layer generation processing for generating a plate data for single-color layer associated with a single-color layer. The plate data for color layer generation processing includes generating a plate data for color layer by reflecting the variable portion in the variable data. The plate data for single-color layer generation processing includes generating a plate data for single-color layer by reflecting the variable portion in the variable data.
