Abstract
A spot color rendering system and method that incorporates spot color press emulation color transformation to preserve spot color on a target rendering device. A spot color rendering option implemented in a graphical user interface can be selected in order to render the spot color via an intermediate emulation space. The spot color name calls can be first associated with a color value in an ICC profile connection space (PCS), as CIE L*a*b* or XYZ. A database relation of the spot color name with its associated PCS numerical value enables association of the name with the resultant color transformed output. Thereafter, a color transformation with respect to the spot color value can be performed in order to compute a color on an emulation press and then the color can be preserved to the target rendering device. Such an approach enables a color consistent rendering to the target rendering device similar to that of the emulation press.
