Controlling Transparency & Gamut Preferences
Transparency & Gamut preferences control how Photoshop displays transparent areas of a document (commonly called the checkerboard), as well as the color and opacity of areas of an image that fall outside of the CMYK (Cyan, Magenta, Yellow, and Black) color mode. It’s important to understand that transparency in Photoshop does not always translate into transparency after you save the file. For example, the JPEG format does not support transparency. When you save the file, Photoshop will fill the transparent areas of the image with a matte color (the default is white). In addition, the Gamut Warning may be activated because a monitor displays color information using RGB, and has more available saturation values than a CMYK document. Using a different ink or spot colors can sometimes fix an out-of-gamut color. For transparency it’s important to remember that unless you’re printing the document directly in Photoshop, it’s the format you choose that determines if the transparent areas will be saved, and the Gamut Warning is there to warn you of any areas that may not print the way you expect. To activate the gamut warning option, open a document, click the View menu, and then click Gamut Warning. Out-of-Gamut areas of the image will display with the color and opacity chosen in preferences.
Control Transparency & Gamut Options
Click the Edit (Win) or Photoshop (Mac) menu, point to Preferences, and then click Transparency & Gamut.
Select the Transparency Settings options you want to use:- Grid Size. Allows you to select a transparency grid size.
- Grid Colors. Allows you to choose the color scheme for the transparency grid.
Select the Gamut Warning options you want to use:- Color. Choose a color to mask areas of an image that move out of the CMYK color space.
- Opacity. Enter a value from 0% to 100%. Opacity determines how much of the Color Overlay masks the original image pixels.
Click OK.
