[68] Overprint Attributes
The images below show white spot data with knockout and overprinting. In this case the spot
data is meant to knockout in order to appear as white in the final document.
[69] Knockout
Spot Flood Fill Layers
If a spot flood layer were required in this file, it would be necessary to place flood data above the
image data layer in order for the Rip to properly process the Spot data. In this case, you would
need to select Overprinting, in order for image data not to be obliterated by spot flood. To
properly view the image, ensure that Overprint Preview is selected. See images below for a
representation of how this will appear.
NOTE
When processing this file in ONYX Thrive, media layers must be set up with a spot
layer to represent this data, as Illustrator identifies this as a Spot, rather than a flood
layer.
