  • Patent number: 8616669
    Abstract: A control device is adapted to control a recording device provided with a nozzle for discharging a color ink and a nozzle for discharging an adhesive fluid. The control device is configured to generate color image data representing a color image made up from color dots formed by the color ink, to generate adhesion image data representing an adhesion image made up from adhesion dots, which are dots formed by the adhesive fluid, wherein the adhesion image data is generated such that the adhesion dots are arranged so that the adhesive fluid is applied at an amount that corresponds to the amount of the color ink applied per unit area and the adhesion dots are arranged so that, when the amount of the color ink applied per unit area is zero, the amount of the adhesive fluid applied differs between inside and outside of a region of the adhesion image.
