true color perception system
This is our most advanced stand alone system that doesn’t require a separate server
controller. The MLC255 is a singular system. Running on our most advanced software
package yet; TC-color scope.
industrial grade environmental duty
With a sturdy aluminum housing the MLC255 series color system is engineered to resist
difficult production environments where temperature, dirt and other typical
contaminants may impede performance.

MLC255 TC-true Perception Color Sensor System
This advanced sensor system can simultaneously process up to 255 colors with individual
tolerances. Tests have shown that the MLC255 TC-true perception color sensor system can
reach a maximum average color resolution of up to ∆E = 0.02 in the L*a*b* mode. Practically,
the resolution in the L*a*b* mode is approximately ∆E < 1 and thus better than the human
eye.
This sensor system provides three main processing methods as described in the following
sections.
Color Sorting:
The actual measured color value is compared with pre-sampled and stored color values.
The best matching color is then the color classification result. A classification is always
done without considering whether the color values really match or not. This method is
widely used for automatic sorting of colored objects.
Color recognition (Color checking)
This method checks if the actual measured color is within one of the tolerance rooms of
presampled and stored colors. The tolerance rooms are predefined by colorimetric ∆E units.
If the measured color is outside the tolerance room, the color check is said to be
unsuccessful (Color was not recognized). This method is widely used for quality checking
of colored products and provides a fast and reliable quality inspection within predefined
tolerance boundaries.
Color sequence checking
This method examines a proper sequence of colors. The color recognition and
classification results are directly sent to the 8 open-collector outputs of the sensor system
and can be coded as “1-out-of-N” (“One hot coding”), 7-segment or as a binary number.
Thus either up to 8 colors, up to 20 colors or up to 256 colors can be represented. The
parameter configuration of the sensor system, as well as the color sampling procedure
(“Teach-in”); is carried out by PC software connected either by RS232 or USB to the sensor
system.
