White Ink Applications
The following are some specific examples of the ways that the white ink workflow can
be applied.
■
Backlit Application
The backlit application involves printing onto a transparent or translucent material
and mounting the finished piece onto a light box or location where illumination from
behind is possible. In the backlit application, white ink is intended to provide a light
diffusing layer. This application is possible using either 2 or 3 layers.
■
Day-Night Application
Similar to backlit, the day-night application also involves printing onto a transparent
or translucent material. A day-night print can be viewed either front-lit or backlit.
This is achieved by printing color data on two separate layers with a white diffusing
layer in the middle.
■
Opaque Application
The opaque application involves printing CMYK data onto non-white media. For
this application, white ink is required both to enable the printer to produce images
where white forms part of the image content, as well as to act as a base for the CMYK
color set.
