I've been trying to get a neutral QTR profile for a while now. The profiles I made are either warm, or cold, or worse, warm on one side and cold on the other. I already made many versions of the profiles. Is there any way to get a true neutral profile, other than by trial and error? Linearization is not a problem, I can linearize them properly. I'm using Windows10, an Epson SC -p600, John Cone inks, Canon Photo Pro Luster paper and Hahnemühle Fine Art Barita.
Thank you
