Whats better: an RGB scan or a CMYK scan?
That really depends on what the image is going to be used for (web, print, cross-media) and your level of expertise. If the scan will only be printed on a conventional press, we recommend that you choose CMYK scans. If you prefer to make your own color separations, you should chose AdobeRGB files. If we are furnishing scans, we can pretty much give them to you any way you like.
