Screen Captures Create a custom CMYK working space that uses GCR and a Maximum Black Generation to replace all four-color gray and black content with shades of process black. Use this custom separation setup when converting screen captures from RGB to CMYK. 6. In the Color Settings dialog box, click Save and name the new color setting. Photoshop will save the color setting in the default location. If you want to save the settings file somewhere else, navigate to that location. You're also given the opportunity to provide a helpful description in the Color Settings Comment dialog box that appears when you save the setting. Type remarks in this field to guide subsequent users of the setting. Click OK to close the Color Settings dialog box. Your new separation setup is now in effect. Comments When you create custom separation setups, enter comments in the Color Settings Comment dialog to help other users understand how to use the setup. Note: This special separation setup remains in effect until you choose another setup. It's appropriate only for converting screen captures and similar images. Be sure to choose a more appropriate separation setup before performing general image conversions. Grayscale Grayscale images are intended to print only in black ink, but beware of images that look grayscale but are actually color images. Photoshop CS3 introduced a special black-and-white color adjustment (Image > Adjustments > Black & White), which provides sophisticated controls for governing the conversion from color to the appearance of a black-and-white image. However, the Black & White adjustment does not actually convert the image to grayscale. Not Truly Grayscale While this image appears to be black-only, the title bar of the document tells the truth; it's actually RGB. Adobe Creative Suite 4 Printing Guide 60
