Patent ID: 8770871

Claim:
An image processing device for outputting printing image data for printing to a printing device for carrying out printing using a colored ink, and a special glossy ink having special gloss, the image processing device comprising: an input part configured to input image data of an image to be printed; a field discrimination part configured to discriminate, based on the image data, whether there is an adjacent field, in which a special glossy field that is expressed in the image data using the special glossy ink and a color production field that is expressed in the image data using only the colored ink are adjacent with respect to each other in a first direction of an image plane; a special gloss boundary processor configured to adjust the image data of the adjacent field so that an ink volume of the special glossy ink affixed to the special glossy field is gradually reduced as the special glossy field approaches the color production field in a second direction perpendicular to the first direction, in a case where the adjacent field is present; and an output part configured to output the printing image data based on the adjusted image data to the printing device.
