When using Adaptive Threshold Processing, there are four
imaging parameters which effect electronic color dropout:
Threshold Value/Filter Threshold, Background
Value/Background, Contrast %, and Threshold. The default
settings are:
Contrast% = 50
Threshold = 90
Color Filter = 175
Background = 245
If the values above do not give you the desired results, you may
need to vary these values accordingly.
When using iThresholding, there are three imaging parameters
which effect electronic color dropout: Threshold Value/Filter
Threshold, Background Value/Background, and Contrast %. The
default settings are:
Contrast% = 50
Color Filter = 175
Background = 245
If the values above do not give you the desired results, you may
need to vary these values accordingly.
The tables that follow provide Pantone colors that may be used
with the red, green and blue dropout option.
Two categories of performance are provided for each color:
Colors that can be completely dropped out and colors that are
very close to complete dropout. These values were established
by using standard Pantone
Matching System® Colors guide
(uncoated, 175-line screen). If the background of the document
you are using is not bright white the results may vary.
