Two White Ink Layers on Black Substrate
Download file: Oce_Arizona_350_GT_WhiteInk_BlackSubstrate.OML
This media model was built using a media with a black print surface. In this instance,
black Polystyrene was used. Due to the darkness of the media it is possible that the media
color will show through. Therefore this media model makes use of two white ink layers
to achieve opaque white coverage, followed by a CMYK image layer, and the result is a
3-layer media model. In this media model, the white ink layers are designated as Spot
layers, so spot data must be either created in an image-editing program prior to opening
in Production House, or it can be set up with Onyx Preflight Spot Layer Tool. To re-
purpose the model for use with flood fill, access the drop-down menu and change from
Spot to Flood Data. If a Flood Fill layer has been defined, no additional file preparation
is required to activate white printing.
