I know I'll probably get chased out of town for asking this. I'm doing some work in PS (CS4), making some signs, the colour profile is in CMYK 16bit. Graphics look amazing, of course, because of the screen. Now I'm ready to have them printed. I export a pdf and a .tif to get a sample of what they look like - and they look totally different! I can't get my head around this - no matter what I try, I cannot get the colours to even look remotely close to the psd file I'm working on. It can't be the screen that makes them look different, because I'm using the same screen to work on! To make myself even more of a noob on this forum, I changed the psd to 8bit CMYK mode, removed the embeded colour profile and saved it as a jpeg. That was the closest I could get to an accurate exported colour, but I dare not send that to a printer! I can't even imagine what it would look like when they are done with it!
