摘要： There is provided a color conversion table having a plurality of pieces of reference color image data making correspondence between color data for a first image device and color data for a second image device and including a specified total information amount. The color conversion table is used to distribute the reference color image data over a prescribed area in a specified color space. Color data information for each reference color image data is increased more than a specified amount within a limit of the specified total information amount. Further, a color conversion table is created using an original table which highly accurately defines colors in part of the table. If such color conversion tables are referenced for color conversion, it is possible to suppress the storage capacity, provide color matching, and perform high accuracy color conversion.

摘要： A printing apparatus performs printing on a printing medium by moving a print head relative to the printing medium in a main scanning direction, which is a width direction of the printing medium, and a sub-scanning direction that intersects the main scanning direction. The printing apparatus includes a print head that includes a plurality of nozzles configured to eject ink; an acquisition unit that acquires image data; and a dot forming unit that controls the print head so as to eject the ink to form dots corresponding to the image data on the printing medium. When suppression dots, which are dots formed to suppress bleeding, are formed on the printing medium, the dot forming unit controls the print head so that ink corresponding to the suppression dots is ejected from preceding nozzles arranged to eject ink to the printing medium earlier than other nozzles of the plurality of nozzles.

摘要： In an image output control system, an image processing device processes image data in accordance with a preset series of image processing and supplies processed image data to an image output device, which outputs the processed image. The image processing device determines the number of dots to be created in each pixel group, which has a preset number of multiple pixels included in an image, and outputs the number of dots as dot number data to the output device. In response to the dot number data, the output device selects one among multiple options for a priority order of individual pixels included in each pixel group, determines the positions of dot-on pixels in the pixel group, and creates dots at the determined positions of the dot-on pixels to output an image. In the image output control system, the image processing device supplies the dot number data to the output device.
