Abstract:
1. A color processing device comprising: a control unit that controls quantity of total ink used for outputting an image by an output device, the quantity of total ink being decided based on quantity of black ink of an input color signal; an optimum black ink quantity determination unit that calculates a necessary black ink quantity as a minimum black ink value required for satisfying a necessary total quantity limit value from a device-independent color signal corresponding to the input color signal to determine the optimum black ink quantity between the necessary black ink quantity and the black ink value in the input color signal; and a black ink control unit that controls quantity of black ink used for outputting the image by the output device, wherein the quantity of total ink includes the quantity of black ink used for outputting the image by the output device; wherein the quantity of total ink is decided based on minimum required quantity of black ink and a characteristic of the output device; and wherein the minimum required quantity of black ink is a minimum value required each black ink value not to intersect each other at lower side outer fringe planes.
