MARKEYE-PRO Registration Mark Sensor Description
The MARKEYE-PRO sensor detects printed registration marks on a continuous web running at high-speeds. It delivers high-resolution by utilizing the broadband characteristics of a white light LED for detecting the greatest variety of color combinations on any color background. The "one-touch" AUTOSET routine can be accomplished by pushing the appropriate button on the sensor or from a remote push-button switch. Simply put the background in view and press the black button if the background is darker than the registration mark or press the white button if the background is lighter than the registration mark. Utilize either apertured V-axis (V4A) lens or fiber optic light guides. We recommend using glass fiber optic light guides for detecting low contrast registration marks. Plastic light guides can also be used as well as a variety of fiber optic accessory lenses to enhance sensing performance.
