Hi Dana and Jon,
I did my best to sniff this answer out of the previous threads, but the closest I came was the custom curves question by JohnB. I followed that but it seems more complicated than what I'm looking for and I don't have the necessary equipment.
My main interest is making nice solid black transparencies for silkscreen and photopolymer emulsion etching. I have had good results with my color set on a 1400 using the greyscale printing, but I currently have the special edition black set in and don't want to change the whole set out.(--I will have to put in the warm neutral shade 1) Is it possible to just print with the solid black channel by making a simple curve or tweaking the linearization? How would I set QTR to print 100% pure black, and could I use this with the color set as well? Or is there some simpler alternative?
Thanks for your consideration, and I hope I didn't miss some completely obvious source for this info....
