Calculation of Density values for grey inks - which approach makes more sense?
2015-10-04 by rafaelrojasphoto@...
HI there again,
I have seen that some authors (like Tom Moore) calculate the density values for secondary grey inks (LK - LLK) by analyzing which level of the K patches are equivalent to the 100% patch of LK or LLK in the inkseparation.tiff print, independently of whether we choose an ink limit of 100% or not for LK and LLK.
However, I have seen some other photographers like Clay Harmon mention that ideally, we should first decide which is the ink limit we allocate for the LK and LLK, and then find their density levels by finding out which level of the K patches are equivalent to THAT ink limit we have chosen. That means that if we decide to lay out a maximum ink limit of 80% for LK, we should find its density value by looking on the printed inkseparation.tiff file where along the K patches we obtain the same density as the 80% (and not 100%) for the LK.
What procedure makes more sense based on the way Roy designed QTR?
I guess we are splitting hairs here, since linearization is going to handle the eventual differences between the two approaches?
Thanks so much!
