Abstract: To prevent ink of printed images on a recording medium from adhering to pinch rollers, a computer determines whether or not a number of images aligned on a same plane by an image combiner are overlapping with a position of a position data representing positions of pinch rollers. As a result of this determination, when any of the images is overlapping with the position of the position data, the computer relocates these images on a same plane to prevent these images from overlapping with the position of the position data. Thereafter, the computer outputs a command to print the relocated images to a printer.

Abstract: A printer includes a clear ink tank, a color ink tank, a clear ink injection head, a color ink injection head, a light source, and a controller. The controller includes a matte printing controller structured or programmed to cause clear ink to be injected from the clear ink injection head and to be irradiated by the light source to form a matte clear ink layer on a recording medium; and a color printing controller structured or programmed to cause color ink to be injected from the color ink injection head to form a color ink layer on the clear ink layer.
