Print Registration/Color Mark/Contrast Sensors
The MCS-638 sensor evaluates the brightness difference
between a target color and a background color.
Sometimes the color difference can be very slight, in
these cases the MCS-638 with its variable color LED light
source is beneficial. The color of the light source is
important, and the appropriate choice of color for the light
source, or using the MCS-638 with it’s automatic light
source color selection allows the detection of very slight
contrasts. For example, a green color LED light source is
more likely to detect a contrast between red and blue
than a contrast between green and blue.
A common application for contrast sensors is a
converting operation. A web of printed media may need
to be cut into individual sheets, and registration marks are
printed in certain locations to signal the machine controller
to cut the media. For example, a continuous sheet of
margarine wrappers is cut into individual wrappers with
the printing centered on each individual sheet. Another
common application is on bag making machinery where
the sensor detects the registration mark and signals the
machine to stop and cut or heat seal a bag.
