Managing Process And Spot Colors - Adobe Photoshop CS6 User Manual

Pure CMYK black (K=100) appears jet black (or rich black) when viewed on-screen, printed to a non-PostScript desktop printer, or exported to an
RGB file format. If you prefer to see the difference between pure black and rich black as it will appear when printed on a commercial press, you
can change the Appearance Of Black preferences. These preferences do not change the color values in a document.
1. Choose Edit > Preferences > Appearance Of Black (Windows) or [application name] > Preferences > Appearance Of Black (Mac OS).
2. Choose an option for On Screen:
Display All Blacks Accurately Displays pure CMYK black as dark gray. This setting allows you to see the difference between pure black
and rich black.
Display All Blacks As Rich Black Displays pure CMYK black as jet black (RGB=000). This setting makes pure black and rich black appear
the same on-screen.
3. Choose an option for Printing/Exporting:
Output All Blacks Accurately When printing to a non-PostScript desktop printer or exporting to an RGB file format, outputs pure CMYK
black using the color numbers in the document. This setting allows you to see the difference between pure black and rich black.
Output All Blacks As Rich Black When printing to a non-PostScript desktop printer or exporting to an RGB file format, outputs pure CMYK
black as jet black (RGB=000). This setting makes pure black and rich black appear the same.

Managing process and spot colors

When color management is on, any color you apply or create within a color-managed Adobe application automatically uses a color profile that
corresponds to the document. If you switch color modes, the color management system uses the appropriate profiles to translate the color to the
new color model you choose.
Keep in mind the following guidelines for working with process and spot colors:
Choose a CMYK working space that matches your CMYK output conditions to ensure that you can accurately define and view process
colors.
Select colors from a color library. Adobe applications come with several standard color libraries, which you can load using the Swatches
panel menu.
(Illustrator, and InDesign) Turn on Overprint Preview to get an accurate and consistent preview of spot colors.
(Acrobat, Illustrator, and InDesign) Use Lab values (the default) to display predefined spot colors (such as colors from the TOYO, PANTONE,
DIC, and HKS libraries) and convert these colors to process colors. Using Lab values provides the greatest accuracy and guarantees the
consistent display of colors across Creative Suite applications. If you want the display and output of these colors to match earlier versions of
Illustrator or InDesign, use CMYK equivalent values instead. For instructions on switching between Lab values and CMYK values for spot
colors, search Illustrator or InDesign Help.
Note: Color-managing spot colors provides a close approximation of a spot color on your proofing device and monitor. However, it is difficult to
exactly reproduce a spot color on a monitor or proofing device because many spot color inks exist outside the gamuts of many of those devices.
