Printing and Intent

[from O'Reilly books]

The Intent setting in Elements Print Preview window is the most confusing of the color management options for most people. Here are the basics of what you need to know to choose a setting. Sometimes your photo may contain colors that fall outside the boundaries of the print space you're using. Intent just tells Elements what to do if that happens. You have four choices:

• Perceptual tells Elements to preserve the relationship between the colors in your image—even if that means Elements has to do some visible color shifting to make all the colors fit.
• Relative Colorimetric tries to preserve the colors in both the source and the output space by shifting things to the closest matching color in the printer profile's space. Relative Colorimetric is Elements' standard setting, and it's usually what you want because it keeps your colors as close as possible to what you see on your screen.
• Saturation makes colors very vivid but not necessarily very accurate. This setting is more for special effects than for regular photo printing.
• Absolute Colorimetric lets you simulate another printer and paper. This setting is for specialized proofing situations.
