So I imagine this is the wanted behaviour and there is no problem with that. We understood wrongly that each patch correspond to one color and should not change. About the profile, I still got bad banding when I try to use the generated profile as a screen profile in gqview for exemple. Here is the result obtains with a shaper+matrix profile applied to the hsv image with cctiff. I also attach tha calibration and the profile file. Do you see an obvious mistake and the way the correct this. I try to follow the doc and always get this behaviour on different screens. THanks for your helpfull advices.
