The EFI Pro 33r can use White as a Spot Ink. For configuring it, there are specific tabs in the "Page Setup" module:
Precisions for the use of white
- To print with White as spot ink, you also need to use a compatible resolution in the print module interface (one that mentions “White” or “W” in the name). Refer to the dedicated article for more information.
- The driver is configured with two White tabs (1 and 2), to give you more flexibility in the configuration (each white layer can be configured differently).
- The driver also includes an additional setting, which allows you to increase the white density to double. This setting is enabled by default, but you can disable it by unchecking the box if necessary.
