I’ve been trying to use the 129 step linearising CGATS spreadsheet to produce a linearised quad file for platinum/palladium on Hahnemuhle Platinum Rag.
The original quad file used to print the 129 step colorport target image was produced using Richard Boutwell’s QuadTone Profiler Quick Curve for Digital Negatives.
I printed the colorport target image for iI Pro, managed to enter the values into the 129STEP_PIEZPDN_CGATS_SMOOTHER excel tool, from which the resulting txt file and original quad file were dragged onto the QTR-Linearise-Quad droplet. The result was the attached “out” file but no linearised quad file. Nor can I find it anywhere on my windows 10 computer.
Any ideas as to where to find the file or why it didn’t work would be welcomed.
