The SMARTEYE® COLORMARK™ ll Registration Mark Sensors combine unique color perception ability with very high speed response. Many important features have been incorporated into the design to meet the increasing demand for precision registration control on today’s higher speed packaging machinery.

The specific task of a photoelectric registration mark detector is to respond to printed registration marks on packaging material as they pass through the sensor's light beam. The output of the sensor must switch when the mark arrives precisely in position for the control function to occur. The resolution of the exact location of each passing registration mark is keynote to ensure that the initiation of the electromechanical response triggered by the sensor is in synchronization with the arrival of the mark.

The high speed (50 microseconds) response time of the SMARTEYE® COLORMARK™ ll helps to ensure that the point of detection of the sensed mark will not shift as the velocity of the moving web varies from slow startup to maximum velocity.

Color perception is a must for detecting registration marks printed in a wide variety of colors. The SMARTEYE® COLORMARK™ ll is recommended for detecting the greatest variety of color of marks and is equipped with a unique combination of white LED light source and photodetector. In addition, there are SMARTEYE® COLORMARK™ ll sensors equipped with red, green or blue LED light sources that are useful in other applications when the preferred white light source fails to perform; i.e., a blue LED light source is recommended to detect pale yellow marks on a white background. Consult selection guidelines to help in specifying the correct SMARTEYE® COLORMARK™ ll to fit your sensing requirements.
