Method for performing color space transformations

Method for the computer-aided execution of transformations of color data for a project from a source color space into a target color space using transformation tables based on a transformation rule, in which a plurality of input color data of the source color space are each assigned unique output values of the target color space, wherein the source color space comprises n colors and the target color space comprises m values, wherein values for the target color space are generated for all input color data of the project using the transformation tables and are provided in a data set by taking the corresponding output values for input color data from the transformation tables, characterized by the following features:

• a) Determine all color combinations of the n colors of the source color space whose color components are not zero;
• b) Generate and store a subspace transformation table for each of these color combinations;
• c) Form all true subsets, including the null set, to each subspace transformation table and generate and store them as separate, redundant subspace transformation tables;
• d) Using the stored subspace transformation tables for the transformation by assigning for each input with its color components of the n colors the corresponding subspace table based on those color components that are not zero.
