A method is provided for printing colour images using a colour workflow. This workflow results in equal output colours from two print systems. For a first print system an existing colour output profile for converting colours is used. An actual output colour profile for the first print system is obtained from colour measurement data that relate device colorant coordinates of the first print system to device independent colour data. The existing output colour profile does not correspond to the colour measurement data. For a second print system, an additional output colour profile is obtained from colour measurement data. The colour workflow that is applied in the second print system for converting colours of an input image is made by combining the existing output colour profile, the actual output colour profile and the additional colour output profile, wherein the actual output colour profile is applied in an inverse direction (A2B).
