Ok, so now and then a web guy needs to print something and usually I can stumble through, but I though i'd ask:
Say I've got this card design. Which I've got at the right size and res(600dpi). Even though the image is grayscale, because it contains different shades etc I'll have to get it printed in full-colour yeah? My understanding is that pms can only be used for flat colours.
See the design here
