A somewhat tricky, oddball question...
After decades of retouching images for commercial printing on offset presses, I can always be reasonably certain of the resulting color in a CMYK workflow. When I retouch for DPC, though, I have to use different settings (obviously) for the RGB world. This usually means making the photo lighter and more saturated than 'normal' CMYK. So my question is- which version would be preferable for submitting to a printing service such as DPCPrints, Shutterfly, Photoworks, etc.?
Ordinarily, I would think that CMYK would be best because the image is, well... printed. On the other hand, my understanding is that this type of printing involves "projecting" the images onto photo paper (RGB), and the vast majority of photos from digicams are submitted as RGB anyway. I've looked for ICC profiles for several online printers and come up empty. Can anyone here provide a definitive answer (beyond guessing) or the results of trying it both ways? I've ordered literally hundreds of prints from PhotoWorks and, while they look beautiful, I've always wondered if I'm realizing the full potential. |
