You won't be able to print in RGB, period. RGB is additive color, meaning that you must ADD the the colors together in some method in order to achieve your image. CMYK (otherwise known as "process color") is Subtractive color, meaning that the colors (Cyan, Yellow, Magenta) subtract color from whatever light source you are working from. You'll need to understand some color theory for this. Think of a red apple. The pigments in that apple's skin to make it appear red, are actually absorbing all frequencies of light EXCEPT the shades of red that you see. In other words, the pigments in the apple's skin are reflecting the red hues back to your eyes. That is a prime example of subtractive color. Now think of a performer on stage: if the lighting coordinator wants to bathe her in white light without using a white light, he could illuminate her in Red, Green, and Blue lights in equal values (brightness) and the cumulative effect would be white light. That is additive color. Additive color cannot be printed. Television, computer monitors, stage lighting, sunlight, flashlights, basically anything that involves a direct energy light source, uses additive color. Anything that reflects light to create color is subtractive color. RGB are primary colors. CMY are secondary colors. Look up a color wheel on the internet, and you'll see what I mean. (Technically, Red, Blue, and Yellow are the three primaries, but not applicable in this case.) CMYK is not the only printing process. There are numerous others, with the more common alternatives being the Pantone Matching System (PMS, used in offset lithography), Hexachrome (six-color process). Chnces are your printer at home and your professional printer are using CMYK, though. (FYI: "K"= Key, or Black, is a separate ink and is used to supplement the CMY and increase tonal depth of your image.) Ok. Now that all of the superfluous color theory has been dispensed with, to get the colors you're looking for out of your photo, you'll need to do some color corrections. So you'll need to know what printing process your printer is using. If they're using CMYK, then convert your image to CMYK and adjust as necessary. Just be sure to think of your image in negative, meaning that if it is "too blue" then try decreasing Cyan, adding Magenta and Yellow (in small increments.) If it is "too red" than try adding Cyan, or decreasing M and Y. Back to the color theory for a short moment (keep this in mind): your monitor will display your image in RGB, while your final printed piece will be in CMYK. For the same reason that RGB cannot be printed, color corrections can sometimes be tricky when using a computer monitor to do them. Monitors can be calibrated, but that's a whole different ball-game, and still isn't 100% accurate. That's why you'll just need to... Experiment, experiment, experiment. That's really the only way you're going to get a feel for how this works. Good luck. --- (PS) Also, to supplement mizmike's answer, don't save your image as a JPEG image. JPEG is a lossy compression format, meaning that when it compresses the image to save file-size, you're losing data in your image, which will affect the final print quality. Save it out as a TIFF file, with at least 300 DPI (Dots per Inch) or 170 LPI (Lines per Inch). Keep it in 24-bit color. Save it with NO COMPRESSION. Don't try to increase the resolution of an image that has already been saved low. That won't work. Work from the original source image. I hope you had your camera set to "fine" and "high resolution"... or your scanner set to scan at "high-quality." (or similar variants of word combinations, vary by manufacturer...) because what looks good on screen doesn't always print nicely. Monitors only need 72 DPI to show images crisply. Printers, on the other hand, usually need at least 300... TIFF files are larger, but that's a good thing! You don't want to compromise your print quality for a few (ok, maybe hundreds in some cases) of megabytes, do you? That's what CD burners are for! :) You are using Photoshop, right? RIGHT? :D
