Hi Walter,
Although my question was about your earlier post, I addressed it to Michael to get the view of another re-separating/re-purposing adherent. No disrespect was intended. But thank you for your positive response.
Have I understood your first paragraph above correctly?: When applied to one CMYK image, the "Optimizer" process may produce some what different values for the same CMYK pixel as the "re-separating" process, but when each is applied to a set of several different images, each process leaves the set of images not only with the same color appearance, but with neutral balances that will respond very similarly to adjustments on press when that set of images are on the same page or press sheet. I am hoping this is what you meant.
But in your first message you stated that the "CMYK -> Lab -> CMYK would negate the effects of the edits." Did you meant to say "the ill effects of the edits," and not the color appearance obtained by the edits? Otherwise, why bother? However, toward the end of your second message you say that if a neutral gray of 38, 31, 30, 14 was edited in CMYK to 50, 40, 40, 0, then re-separating it back to the original GRACoL profile would restore the initial CMYK values of 38, 31, 30, 14. But then the desired color appearance from the edits is lost. Then this is not a work around with results similar to "Optimizer" process.
This seems contradicting. I must not be understanding this properly. Can Walter or someone else please clarify.
Thanks,
Al
