In the backlit application, white ink is intended to provide a light diffusing layer. Thisapplication is possible using either 2 or 3 layers.• Day-Night ApplicationSimilar to backlit, the day-night application also involves printing onto a transparent ortranslucent material. A day-night print can be viewed either front-lit or backlit. This is achievedby printing colour data on two separate layers with a white diffusing layer in the middle.• Opaque ApplicationThe opaque application involves printing CMYK data onto non-white media. For thisapplication, white ink is required both to enable the printer to produce images where whiteforms part of the image content, as well as to act as a base for the CMYK colour set.White Ink Workflow OverviewChapter 9 - Manage a White Ink Workflow 129
