Printing White Ink
Top off ALL of your White Ink cartridges to the 150ml mark at the
beginning of each day and DO NOT allow the ink levels to drop
below the 100ml mark or you risk ink starvation issues. If the printer
has been unused for a few days, perform two or three regular
Head Cleaning cycles to get the White ink owing properly.

FastARTIST. When Underbasing solid, Spot Color images, generally you’ll print
solid White ink and then follow that pass with CMYK. When using FastARTIST,
and the image has White as part of the design, a second pass of White can
be made at the same time as the other colors. This second pass of White is
called a Highlight and it boosts the brightness of the White.
When printing photorealistic images, you will need to run a special routine 2.
called the Underbase Wizard. This feature of FastARTIST will create a separate
piece of artwork that FastRIP will use to print an Underbase of White ink. When
printing a photorealistic image, the Underbase is NOT solid White but instead
it is Grayscale. Grayscale consists of light and dark areas that give the image
dimensionality. This is the art to printing bright and soft prints on Dark garment.
You must tell FastRIP what 3. Print Modes to use for both the White ink and Top
Colors. Once you have made these selections, they can be used again for
other jobs. For Dark shirts you can get very good “Screen Print” quality White
if you select a 1440 DPI Print Mode for the Underbase. For the top colors of
Cyan, Magenta, Yellow, Black and the highlight White, choose a 720 DPI Print
Mode.
For medium colored shirts, use a 720 DPI Print Mode (faster than 1440 DPI) 4.
for the White ink Underbase. In some cases, very light colored shirts may not
even need a White Underbase. These images can print using just CMYK and
highlight White to save printing time.
We recommend you DO NOT mix Print Modes. You will notice that
certain Print Modes contain a ‘HS” or “HS (Bi-Directional)” while the
standard Print Modes contain neither. DO NOT use standard Print
Modes in conjunction with HS Print Modes. The result may lead to
registration issues and ruined prints. Please note that this warning is
not referring to print resolution, i.e. 720 or 1440 DPI. Print resolutions
can be mixed and matched as needed. If you are not sure how
different Print Modes work together, do a test print before doing
a production run. For more information on Print Modes, refer to
