I’m wondering how you’d quantify a neutral toned print? I primarily print on Photo Rag Baryta, William Turner and Epson Semimatte. Three very different papers, one with OBAs, two without OBAs or minimal amounts of them. I don’t ever expect images printed on a paper to match tone-wise to a different paper - I’m aware that neutral on a print is relative to the paper’s base color.
I know I can read the a* and b* values from measurement patches and see how closely they track to neutral on a given paper (and try to bring them closer to the neutral axis with the blender tool). But is it realistic to expect a print to ever be truly neutral, given the warmth/coolness of each paper’s base? If not, is there a range or tolerance of a* b* values that’s effectively neutral in everyday printing?
I pulled some untoned silver gelatin prints out of my drawer to compare, and while they look neutral to me (under my Just Normicht d50 booth), if I take some spot readings with my i1 the values actually go a bit on the cool side.
