MATRIX 320
Color Contrast Considerations
Matrix 320 models are available in White, Blue, and Red Light versions to help resolve
applications that have colored codes and/or backgrounds.
The choice between the white, blue or red illumina-
tor 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 illumi-
nated 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 tar-
get according to the color of the illuminator, modify-
ing the contrast between target and background.
See the examples below.
