US Patent 9840089 Printer, printing system, and card manufacturing method

An input unit receives first image data corresponding to a first print image of a first ink. A density acquisition unit acquires a density value of each pixel included in the first image data. A glossy image density decision unit sets a gloss density value to the minimum possible value of the gloss density value when the density value of the pixel is less than a predetermined value, and sets the gloss density value to a value larger than the minimum possible value when the density value of the pixel is equal to or greater than the predetermined value. A dithering processor performs dithering based on the set gloss density value to create second image data corresponding to a second print image of a second glossy ink. A transfer device transfers the first and second print images on a print body to form a glossy image on the print body.
