To display and output spot colors using Lab values
Some predefined spot colors, such as colors from the TOYO, PANTONE, DIC, and HKS libraries, are defined using
Lab values. For backward compatibility with previous versions of Illustrator, colors from these libraries also include
CMYK definitions. The Swatches palette lets you control which values Illustrator uses to display, export, and print
these spot colors: Lab or CMYK.
Lab values, when used in conjunction with the correct device profiles, give you the most accurate output across all
devices. If colormanagementiscriticaltoyourproject,Adobe recommends that youdisplay,export, andprint spot
colors using their Lab values.
Note: To improve on-screen accuracy, Illustrator uses the Lab values automatically if Overprint Preview is on. It also
uses Lab values when printing if you’ve selected Simulate Overprint in the Output panel of the Print dialog box.
1 Choose Spot Colors from the Swatches palette menu.
2 Do one of the following:
• Select Use Standard Lab Values Specified By The Book Manufacturer if you want the most accurate display and
output of colors.
• Select Use CMYK Values From The Manufacturer’s Process Book if you want spot colors to match earlier versions
of Illustrator.

To use the Swatches palette
You use the Swatches palette to control all document colors, gradients, patterns, and tints. You can name and store
any of these items for instant access. When a selected object’s fill or stroke contains a color, gradient, pattern, or tint
applied from the Swatches palette, the applied swatch is highlighted in the Swatches palette.
