White tab
EPSON SureColor SC-F3000 uses a White Ink. For this spot ink, there is a specific tab in the Page Setup window, to be able to configure it.
Please refer to this article to have details about this Spot Ink specific tab. And check this section to have tips and details about Spot ink features.
White ink and T-shirt modes (Direct-to-Garment modes)
The white tab behavior changes when using Black T-shirt and Colored T-shirt print modes.
These print modes are designed to automatically generate an optimized white underbase layer. In most cases the best results will be achieved by leaving the Enable Separation option unchecked. This will cause CalderaRIP to automatically select the best white generation settings, depending on the artwork type being printed.
If Enable Separation is checked, you should select the starting point for the white layer. For example the Alpha channel in a raster file, or Generate from CMYK data, with Generate where there is some ink computation, for art files without an alpha channel.

Note: This selection only acts to a guide as to where white ink might be needed, the RIP will automatically adjust the level of white according to the colors being printed.
Preparing art files for Direct-to-Garment (DTG) printing with CalderaRIP
It is recommended to use art files without a specific white underbase layer included. Often this means:
- a PNG image with an alpha channel defining transparent areas.
- raster or PDF artwork with a spot white channel defining pure white areas
- if fades to garment color are required, a raster image (eg. PNG or TIFF) with an alpha channel should be used.
Any of the above artworks can be printed using the Caldera T-shirt print modes to generate a color managed and optimized white layer.
If it is required to print an art file which already includes a white underbase channel or spot, CMYK print mode should be used, and the white channel set up in the White Ink tab. However it is not possible to properly color manage the output in this case, and results may not be optimal.
