John Lam is talking about digital photography work flow... I can totally agree with the fact that color matching is such a huge pain. I worked in a tee-shirt shop for a while and the on screen colors of the Mac was so far off from what eventually was on the custom designed shirts (printed from the mac to a color laser printer with thermal transfer paper that was then pressed on the shirt) that we had to have a color swatch and try to talk customers out of believe what was on the screen.

At home, I continue to have problems with printing my pictures. Every Photoshop book that I read devotes about 25% of the book to color. Experts at Microsoft that I have talked to have gone into great depths as to the root cause of all these problems - however it is apparent that today getting accurate color between the camera, screen, and printer is basically impossible for a mere mortal like myself.
