Assign a spot color to a printer ink channel

If your printer supports white ink, clear ink, or metallic inks, you can assign one of these printer inks to a spot color definition. The printer inks are printed either behind or on top of the spot color.

Before you begin, make sure you have added a custom spot color.

You can use this feature to:

Simulate the final production run on a white or colored media.
Create interesting special effects using gold or metallic inks, as seen in the packaging industry. The possibilities are increased if your printer supports multi-pass (multi-layer) printing. Be aware that to create such special effects, you must also make printer-specific settings (see our printer supplements on www.help.efi.com).

Under My Custom Spot Colors, select a spot color.
On the Color Definition tab, under Apply as, click the ... button.
In the table, scroll down to Printer Color System, click the Add (+) button to expand the content, and select the printer ink that you want to assign to the spot color.
Some settings have an “inverted” equivalent. They can be recognized by the letters “INV” in their name. If you select an inverted setting, the inversely proportional amount of ink is applied - for example, 0% color instead of 100% color, or 70% color instead of 30% color.
Click Use Selection.

You can also remove the link to a printer ink channel in the Apply as dialog box.
