But my reasoning was "if PY151 gives me a neutral black at a specific proportion to M and C - also keeping the constant the proportions of M and C to each other, then, since I'm calibrating all colors separately so that they give same luminosity on print, for the same gray value on screen, they should continue to give me neutral colors on the step tablet test when I print them on top of each other"... Maybe it's a too long / complicated sentence but I hope it describes well my approach. Will definitely print the colors together, to decide and see how much they have to be diluted for a good tricolor print... > Being an old-fashioned gal who was printing tricolor a long time > before it got so gol-darn complicated, I'd personally recommend just > throwing caution to the winds and printing tricolor.

But, each to his own. I agree, since I too have experienced this. What I'm trying here is doing it in a more controlled fashion, and to get (maybe marginally!) better shadow and hightlight detail. I have to do it as precise/controlled fashion as it can be at first, to be able to work in a free / intuitional style later. Just like in learning painting, you can't (or shouldn't) go directly to abstract painting without first climbing the classical steps... Believe me I'm not trying to get it more complicated than what it is -> just want to settle on a simple style based on experience with complicated test / working procedures... Thanks, Loris.
