  • Color accuracy vertfication device that manages color accuracy of plurality of printers
    Patent number: 11150136
    Abstract: A color accuracy verification device includes: a hardware processor that: acquires a colorimetric value for each color patch of color accuracy verification charts generated by a plurality of printers; stores the colorimetric value in time series; sets a target printer to carry out color accuracy verification; and verifies color accuracy based on: the colorimetric value of the target printer stored in the hardware processor; and a verification reference value set in advance; and a display that displays a verification result by the hardware processor for the target printer.
    Type: Grant

  • Color verification apparatus, color verification system, and computer-readable storage medium storing a program
    Patent number: 10521706
    Abstract: A color verification apparatus according to an embodiment of the present invention uses a color measuring instrument to measure an estimation object in a printed matter including a RIP image formed by an image forming apparatus and thereby acquires a measured color value of the estimation object. The color verification apparatus calculates an estimated color value of a color verification target object from the measured color value of the estimation object and a conversion coefficient. The color verification apparatus performs color verification on the color verification target object in the printed matter based on the estimated color value of the color verification target object and a theoretical color value of the color verification target object when it is determined that color measurement is unavailable to the color verification target object.
