RGB vs. CMYK Images and Ink-Jets

When you print your images to an ink-jet printer, you will in most cases be printing an RGB image rather than a CMYK color space file. In fact, with many ink-jet print drivers and RIPs, if you send a CMYK file to the device, it will first convert it back to an RGB color space, and then perform its own conversion to CMYK. This is not good! Avoid this process at all costs, because your image will be converted through two color spaces and you have no control over that conversion. When in doubt, send an RGB image to an ink-jet.
