But in short, yes. You are correct,
There are more advanced ways to make ICCs for printing with in the PPE but it requires i1Profiler application at the moment. So run QTR icc tool for now.
I’ve linearized a curve now by following the instructions in the deluxe edition manual, reading a 51 step then the 129 step chart for i1profiler.
If I wanted to next create an ICC profile, am I right in thinking that I need to reprint the 129 step chart, read it, and then drop the saved CGAT LAB data onto the QTR ICC tool?
Sorry if this has been covered elsewhere
