Yes, I could realize some of these questions and I finally decided to change my logo and all communication visual concept for the next year, migrating to a cleaner design. Then, I won't use black backgrounds anymore in order to avoid that kind of stuff. The biggest problem is that each website says a different thing about we know as "rich black". Is there an universal value to get the correct "rich black" CMYK value? I found on this page something about it, so I hope you can tell me if I should trust in that content: http://www.bittbox.com/all/photoshop-101-true-black-cmyk On the other hand, I have some basic questions about how to prepare correctly a file for printing. The 1st question I wanna your help: Is there some general guide across internet (if is a Corel-based guide it would be better) with the main steps or issues that I have to check before sending my files for printing? One of the things that confuses me is about the difference between using, for example, black 0 0 0 100 or if I should apply the value 100 for all CMYK channels. I'm a web professional, so my skills are around RGB, so that kind of question could sounds like as "very very stupid" for you, then I'm really sorry about that! The 2nd point: If I wanna pick a color from some website (the HEX value) and put it on Photoshop and get its CMYK value, it will be the real color when going to print? Is there some way I have to follow to "convert" a RGB or HEX color to a CMYK color? What worries me is to use (and see) a color on the screen and, after printing job, get that same color different from what I used on my layout. How to avoid that problem? Thanks for everyone and for every reply. It's a little bit "hard" for me to understand the "printing" world. I work and sell business card and logo design service since 2 years, but I always tried to say to my customers "do not use black backgrounds", it always gets me in trouble.
