Patent ID: 6956672

Claim:
A method for mixing inks to facilitate high fidelity color reproduction for printing, the method comprising the steps of: computing a first color space using a forward printer model and a first colorant space, with the first color space having no black ink values from the first colorant space, thereby establishing a relationship between the first color space and the first colorant space; computing a second colorant space using the forward printer model wherein each point in the second colorant space has one corresponding point in the first color space; Computing a second color space using the forward printer model and CMYK ink values; computing a third color space by comparing the second color space to the first color space to determine which color points in the first color space require black ink; computing a third colorant space using the printer model and the third color space, wherein each point in the third colorant space has a corresponding point in the third color space; computing a first color space by calibrating and correcting the third color space; linking the fourth color space with the third colorant space using the forward printer model, wherein each point in the fourth color space has a corresponding point in the third color space; and forming a color reproduction table using the fourth color space and the third colorant space, for receiving a data input and providing a colorant output for use in mixing inks for high fidelity printing.
