I have a book ready for printing. But, of course, it was done in RGB. In fact, I stretched the RGB gamut beyond its normal range in order to make it more painterly etc.
When I saw it converted to CMYK, I almost passed out. All the great colors I had achieved in RGB had been dulled and "grayed". It was a great disappointment even after infinite tweaking of the CMYK colors in a futile attempt to get them back to match the original RGB colors. Worst of all was the color blue. No matter what I did in CMYK to restore this very important color, all I got was a gray-blue.
Is it possible in this remarkable age of technology that there is no printing press that can print a book directly from RGB?
