Abstract
The invention provides a method and computer program of instructions for specifying a device independent trap color in a color space for a color boundary. The method includes obtaining a first color value (C), representing a first color in a color space associated with the color boundary, having a first darkness and first chromaticity and obtaining a second color value (C), representing a second color in the color space associated with the color boundary, having a second darkness and second chromaticity. The method includes generating a trap color value, representing a color in the color space, having substantially a same darkness as a lighter of the first and second color value, and a chromaticity that is a function of the first and second chromaticities of the first and second color values.
