Symptoms

Duotone spot colors from Photoshop 5.02 cannot be translated to their process color equivalents. The result is that the image renders the duotone spot colors to their spot plates.

Cause

Solution

The duotone image should be first converted to a CMYK image and then saved as a Photoshop EPS. The EPS that is created can be included into the separation workflow and rendered on the process color plates.

This is a problem only if the intent is to convert the spot colors in the duotone to their equivalent process colors. If the intent is to leave the duotone spot colors as is and to render them to their spot plates, then the Photoshop 5.02 duotone images saved as Photoshop EPS files work fine.

(Note that in composite workflows, a Photoshop 5.02 duotone can be converted to process in a composite workflow whether it is included in the PS or if OPI is used prior to normalizing. If the intent is to leave the duotone spot colors as is and to render them to their spot plates then the Photoshop 5.02 duotone images saved as Photoshop EPS files work fine.)

Permanent fix: There is no safe solution to this problem that can be implemented in Extreme or the OPI engine in the short term. A long-term solution might require collaboration with the PhotoShop team.
