Color Contrast Considerations for DPM Applications
Matrix 300N DIF / MLT-DPM models are available in Red and Blue Light versions
to help resolve applications that have colored codes and/or backgrounds.
The choice between the blue or red illuminator
should be done in order to maximize the contrast
between the code and its background; in general,
a code illuminated with a light of the same color
becomes brighter, on the other hand when
illuminated with an opposite color it appears
darker (see the Chromatic Circle Chart).
Consequently during the reading phase the
lighting system changes the chromatic rendering
of the target according to the color of the
illuminator, modifying the contrast between target
and background. See the examples below.
