Abstract
The present invention relates to a method of determining optimum color density and gamma curves and includes a step of providing a first set of input color values representing a set of Cyan, Magenta and Yellow values corresponding to a desired output color. An array of color output simulations is output using the first set of input color values, the array consisting of a plurality of individual color samples having varying amounts of Cyan, Magenta and Yellow which differ by predetermined percentages. The sample which corresponds most closely with the desired output color is selected and the Cyan, Magenta and Yellow values corresponding to the sample are determined. The gamma correction curves which are used to adjust the input color values are adjusted by using the determined Cyan, Magenta and Yellow values.
