Pantone color values in Photoshop differ from values in InDesign and Illustrator (CS-CS2)

Issue

Pantone color values set in Adobe InDesign or Adobe Illustrator appear to be different colors in Adobe Photoshop.

Detail

You are comparing the CMYK and Lab color values of the Pantone colors in Photoshop, Illustrator and/or InDesign.

Solution: Set the applications to use the Lab values in the library (InDesign CS2 and Illustrator CS2 only)

In InDesign CS2:

1. Open the Swatch palette and select Ink Manager from the palette menu.

2. Select "Use standard Lab values for spots".

3. Re-create the spot color.

In Illustrator CS2:

1. Open the Swatch palette and select Spot Colors in the palette menu.

2. Select "Use Lab values".

3. Re-import the spot color.

Background information

For InDesign CS2 and Illustrator CS2:

You must set InDesign CS2 and Illustrator CS2 to use Lab values that are in the library; this is not the default setting for either application. When you set InDesign CS2 and Illustrator CS2 to use the Lab values, you can encode alternate colors for spot colors using the same Lab values. If spot colors are converted to process colors, then Illustrator CS2 and InDesign CS2 convert those Lab values to CMYK using the Profile selected at print time or using the document profile if the conversion-to process happens before print.

For InDesign CS and Illustrator CS:

There is no setting to use Lab values in Illustrator or InDesign in versions earlier than CS2. Neither application used different Lab Pantone values; both were designed to use the Pantone CMYK values to define color appearance, while Photoshop uses Lab. This was changed In InDesign and Illustrator CS2.
