Abstract
A method of generating transfer functions to be applied to the input data of an image to be printed by a printing apparatus using a group of colorants, each colorant being assigned to the rendering of a distinct color channel, includes determining a maximum total area coverage and measuring the tonal response of each colorant. The method further includes setting a maximum individual area coverage for each colorant such that the optical density at the maximum individual area coverage is substantially the same for each colorant and the sum of the maximum individual area coverage values is substantially equal to the maximum total area coverage and generating a transfer function for each color channel based on the set maximum individual area coverage for the assigned colorant. An apparatus and a computer program product are provided to generate such transfer functions.
