optimizing an image for print

[timin]

when changing a rgb pic into cmyk, the blacks seem to lose it's blackness and become sort of grey. i don't quite understand how to optimize an image besides using a high dpi.. and that's about it.

anyone have any suggestions and tips about optimizing images for print? anything would be suweeet.

thanks,
timin

Yeah there's no 100% black.

I remember somebody once telling me to add...purple was it? I dont remember....but if you add some other colour, it mimics black.(Cone probably knows more about this)

Here's THE most important tip on print though, START off with CMYK, dont ever start with RGB and switch to CMYK. You will age faster that way :P


Im moving this thread to DTP since its more at home there.

Use K=100% and C=60%.

Changing a image from RGB to CMYK, shouldn't be a problem.

there will of course be some colour difference, since CMYK has less coloures than RGB.

The whole black issue is can be quite the bitch i know, simply add some contrast to your image after changing it to CMYK. That usually works for me. :)

You mean for the black right? But in general you loose colours right? Since the CMYK colour gamut is smaller than the RGB gamut

Yes in general you loose coloures because of the colour gamut like you said.

But if you pick and RGB black (0/0/0) and turn in into a CMYK black it shouldn't become around (70/70/70/90) black, wich is not that vague, but of course you lacking that last 10% of the black colour.

It may look vague on the screen, but shouldn't be that vague when printed. Of course 100% black is better, and with contrast/brightness you should be able to fix that tproblem. :)
