- Clearly the quality and reproducibility of color reproductions is dependent on good calibration of all devices (scanner, monitor, digital printers and proofers, imagesetters, plate exposures, presses etc.)
- Like the Supreme Court Justice who said “I can’t define pornography but I know it when I see it.”, bad color separations are easy to identify, but not necessarily easy to fix. .
If the monitor RGBs were ideal (the same as what the cones are sensitive to) with a linear response (gamma = 1) and the CMY pigments are ideal (the exact complements of RGB) then the transformation to CMY would be simple.
It would essentially correspond to the linear formulae given in the book
C = 1 - R/R0 M = 1 - G/G0 Y = 1 - B/B0
where R0, G0 and B0 are 255 corresponding to their maximum values.
