If a job contains undefined spot colors, an error message appears in the Job Summary area of Job Center. Jobs with unknown spot colors cannot be printed correctly. You can define unknown spot colors in Job Editor.

1. In Job Editor: On the sidebar, click Color. On the Color tab, expand the Spot Colors panel.
2. In the table's Source column, click the down arrow next to an unknown spot color, and do one of the following:

   • To map the spot color to a color from the internal spot color library, select a spot color manufacturer.

   • To enter color values, select a color space such as CMYK or L*a*b*.

   • To create an alias to another spot color in the spot color table, select Alias.

     An alias creates a fixed link to an existing spot color. It ensures that two spot colors use the same color values, even if they have different names. Use this setting to tweak colors, or as an alternative to renaming a color in the graphics program. if you make changes to the original color, they are applied to the alias color also.

   • To assign a spot color to an additional printer ink channel, such as one that contains a spot color, white ink, clear ink, or metallic ink, select PRINTER.

     Command WorkStation bypasses color management for printer inks.

3. In the Map to column, do one of the following, based on your selection in the Source column:

   • Spot color manufacturer: Select a color from the internal spot color library.

   • Color space: Enter color values in the selected color space.

   • Alias: Select Cyan, Magenta, Yellow, Black, or any custom spot color from the current spot color table.

   • PRINTER: Select a printer ink channel.

     You can assign a printer ink in addition to the original spot color definition. The additional inks print either behind or on top of the original spot color.

     The PRINTER setting is useful in the packaging industry, where gold or silver metallic colors are often used.

     Some settings have an “inverted” equivalent and have the letters INV in their name. If you select an inverted setting, Command WorkStation applies the inversely proportional amount of ink—for example, 70% color instead of 30% color. An inverted setting allows you to simulate the final print run on any colored media.

4. In the Apply as column, select a printer-specific color (optional).

   This feature allows you to create many interesting special effects, particularly with multi-pass (multi-layer) printing. Be aware that to create such special effects, you must make printer-specific settings on the Special Settings panel.

5. Repeat the above steps for all unknown spot colors.
6. Click Save.
