The driver includes a default inkset, representing the printer’s minimum supported ink configuration.

If your license allows it, you can customize this inkset by adding, removing, or rearranging inks across channels to create a configuration that matches your setup. Click Edit to open the Ink Channel Configuration wizard.

Ink Channel Configuration

Available in Caldera Direct-to-X RIP v2.3.x (and later).

The Ink Channel Configuration window allows you to define and verify the mapping between software-defined ink channels and the physical printhead configuration:

Channel Mapping: Add, remove, or drag inks to match the order of the printer’s physical ink channels. Up to 13 ink slots can be configured. Each slot represents a numbered position and displays the assigned ink with a colored drop and label (for example, C, M, Y, K).
Ink Order Check: A verification pattern can be printed to confirm that the configured ink order matches the actual printer output. The panel on the right shows the currently selected:
