  • Patent number: 9658556
    Abstract: An image data processing apparatus includes a total-colorant-amount calculating unit that calculates a total amount of a metallic colorant and a process-color colorant used by an image forming apparatus to form an image having a unit area, the image forming apparatus forming an image by using a white colorant, the metallic colorant, and the process-color colorant; a white-colorant-amount specifying unit that specifies an amount of the white colorant used to form the image having a unit area on the basis of a calculation result obtained by the total-colorant-amount calculating unit; and a white-colorant-amount correcting unit that corrects the amount of the white colorant so that the amount of the white colorant used to form the image having a unit area decreases as the amount of the metallic colorant used to form the image having a unit area increases.

  • Patent number: 9641728
    Abstract: An image data processing apparatus includes a white-colorant-amount specifying unit that specifies an amount of a white colorant used by an image forming apparatus to form an image having a unit area, the image forming apparatus forming an image on a recording medium by using the white colorant and at least one process-color colorant; and a process-color-colorant-total-amount adjusting unit that adjusts a total amount of the at least one process-color colorant used by the image forming apparatus to form the image having a unit area. The process-color-colorant-total-amount-adjusting unit adjusts the total amount of the at least one process-color colorant so that a sum of the amount of the white colorant and the total amount of the at least one process-color colorant used to form the image having a unit area is constant.

  • Patent number: 8736909
    Abstract: According to an aspect of the invention, an image forming apparatus includes an image correction unit and a determination unit. The image correction unit inserts a new pixel between pixels forming image data with a plurality of pixels printed using a plurality of print color materials arranged in a main scanning direction in order to correct the image width in the main scanning direction. The determination unit determines whether or not the image data is specified for print with a dot representing given information superposed. When the determination unit determines that the image data is specified for print with the dot superposed, a prohibition unit included in the image correction unit prohibits insertion of the new pixel into a pixel string of a print color material of a similar color to the print color material for the dot.

  • Patent number: 8699083
    Abstract: An image processing device includes a screen processing unit and a correction processing unit. The screen processing unit executes screen processing for an image to be processed. The correction processing unit performs correction processing of correcting a distortion of an output image from an original image, based on the amount of the distortion, for (i) the image before the screen processing and (ii) the image after the screen processing. The correction amount relating to the correction processing for the image after the screen processing is a small value as compared with the correction amount relating to the correction processing for the image before the screen processing.
