I already heard that when we're gonna pick a correspondent CMYK color from a RGB one, it's "recommended" increasing saturation and brightness in order to get a better printing result, because every color when printed on uncoated paper (regardless pantone), they "become" darker and less saturated.
I'd like to know from you if that's true. I already saw that proof when I downloaded a visual identity manual from a bank here in Brazil and I could notice that their CMYK choice is brighter and has a little bit more of saturation. Here are those colors just to give you an example of what I'm talking about:
Their RGB is 204, 9, 47. Their CMYK is 0, 100, 75, 4.
UPDATE: the print shop contacted me and they said me to proof colors using FOGRA39. That generated a BIG difference in comparison with default US Web Coated Swop v2.
