Hello@all in the attachment you will find ti3-data from a packaging print I´ve tried to profile using Argyll V.1.3.5. No matter what I did, I wasn´t able to get a decent result, so maybe on of you guys have a better idea. The print is very inconsistent, especially the gray-axis. Anyway -this is quite a real-life situation in packaging. I tried also to build a profile using other packages (e.g. PrintOpen). The results where somehow better, but still not satisfying. Maybe this example also could be a good test-item for Graeme? Some parameters needed: Total area coverage: 340% The separation should be UCR (under colour removal) The black should start at approx. 25% an reach his maximum at 95% Thank´s in advance for any input.
