I drove a Scitex RIP (raster image processor) as my part time job in college. The CMYK (and if you were rich, N more spot colors) rotation degrees were held in religious fervor. Me: "These degrees seem random." Boss: "You are not to ever digress from those, they are the Only True Values" (and if you play with them in TFA you'll see it indeed becomes a moire mess with tiny tweaks, which would cost a ton in reprinting and delays).It was mildly humorous that stochastic dithering (even with dot-gain compensation) was an option back in 1990, and produced much higher grade color reproductions, but clients wouldn't have any part of it, because it wasn't "the look" that I think they expect their readers expected.
