Patent ID: 8913289

Claim:
A control device configured to control a print device that forms an image on a recording medium based on image data in which density values of multiple colors are defined every pixel, the image data including data representing different types of objects, the control device comprising: a stored color setting unit configured to independently set, for a plurality of the objects, color material designation information in response to user input, the color material designation information indicating a unrestricted toner color for a respective object, the non-restricted toner color being one of a plurality of toner colors usable by the print device whose density is unrestricted for the respective object; and a determination unit configured to determine, for each of the objects, density values of the respective non-restricted toner color based on the color material designation information, such that a total sum of the density values of the plurality of toner colors used to produce the respective object is within a value subtracting a density value of the non-restricted toner color from a reference value.
