Patent ID: 8305641

Claim:
An image-processing system for printing an image based on original image data having a color value, the image-processing system comprising: a storing unit that stores at least one look-up table in association with at least one printing condition, the at least one look-up table being used to convert a color value in original image data into a limited color value that limits a total quantity of ink to be used in printing; a detecting unit that detects, as a printing condition, at least one of a type of color material and a type of recording medium which are used for printing operation; a converting unit that converts the color value in the original image data into the limited color value by using a look-up table that is assigned with a printing condition corresponding to the detected printing condition; a determining unit that determines whether the detected printing condition corresponds to one of the at least one printing condition assigned with the at least one look-up table; and a creating unit that creates a new look-up table corresponding to the detected printing condition when the determining unit determines that the detected printing condition does not correspond to any of the at least one printing condition assigned with the at least one look-up table stored in the storing unit.
