My question is how far out can your gray balance be at standard densities and the software still be able to create individual cmy curves that will result in gray balance?
Reason I’m asking is we find gray balance on press with linear plates at 148-135-100 cmy, and used one curve. Now we seem to be having trap issues with the CM and would like to bring the cyan density down but when we print the grayfinder target at standard density 145-145-100 cmy it is way too red overall to find a gray patch on it that’s useable to plot individual curves manually. Can anyone tell me if there is a way to do this manually in this case or if the software will take care of this for me?
I need to be able to do it manually so press can go back to standard densities and maybe get rid of CM trapping problem, or be able to justify the cost of the curve software to do this for me if no way to do it manually?
