5 Use white ink
Introduction
With the white ink option available from HP, you can replace the light magenta and light cyan inks
with white ink, resulting in four colors of ink plus white ink. This enables you to print with white ink
using various techniques.
Printing with white ink may require special preparation of the image to be printed or special setup in
the RIP. Refer to the documentation provided with the application software and RIP for step-by-step
procedures.
White ink option overview
White ink printing is available as an option that can be delivered with a new printer or as a field
upgrade to an existing printer. If the option is delivered with a new printer, it is installed with the new
printer. In the case of a field upgrade, the option is designed to be installed either by a service
technician or by the customer operator.
The white ink option consists of two parts (see instructions that accompany the kit for detailed
instructions):
● White ink option upgrade — a one-time process that upgrades the printer to a white-ink capable
printer
● White ink conversion — replaces the existing light cyan and light magenta inks in the printer with
white ink.
Refer to the White Ink Upgrade Kit Installation Instructions, HP part number CQ114–90006, included
in the white ink upgrade accessory kit, for detailed instructions for the upgrade and conversion.
Types of white ink printing
Many different design effects can be achieved with white ink that would not be possible otherwise,
especially when printing on dark, colored, metallic, or clear media. There are three basic design
techniques for printing with white ink:
● Under-fill — a solid rectangle (or irregular shape) of printed white ink that is cured, then a color
image is printed on top of it. When used on a non-white, transparent, or reflective surface, this
can provide better color saturation or allow colors that are similar to the media color to be visible.
● Over-fill — a color image is printed and cured, a solid rectangle (or irregular shape) of white ink
is printed on top of it. This is most often printed on clear media to create a sign that is viewed on
a light box (for example, a shopping mall map, airport advertisement, or bus stop signage).
When viewed from the opposite side of the media on which it was printed, the image must be
reversed (mirrored) in the RIP or application software before printing.
● Spot color — any white shape (including text) that is cured with and in the same plane as the
rest of the artwork, rather than in a separate plane or layer. In conventional (analog) offset or
screen printing, this might be called a “knockout,” because none of the colors are overprinted.
NOTE: When printing a CMYK or CMYKcm image without a white under-fill on non-white
media, color saturation may be reduced, depending on the color of the media used.
