Manipulating light, dark, middle in base curve
2019-03-15 by per@...
Hi all,
I am making a digital negative base curves for a p800 with stock inks, and have successfully figured out how to get ink limits and densities for the grey inks, and have heuristically added a little shot of the rest. Once I print the first cut step wedge, I may see for example that the darks need adjusting up or down (last two steps too similar), the lights needs adjusting up or down (first two steps too similar), or the the middle need to move up or down.
My question is now: What is the easiest way to do get the base curve as close as possible before graycurving and linearizing? I want to do this in a systematic way without one change affecting the whole system. How does the graycurve box items for highlights, shadows and gamma affect this?
I could solve this by a random walk of parameter tweaks but I much would prefer a systematic approach as I am not just making a single curve, but aim to do a bunch of different processes.
Kind regards,
-Per
