Contrast Sensing Application - Guiding on Negative Spaces

By pedro on

Contrast sensing allows for a variety of applications to guide or monitor your web. These applications help you eliminate the need for a printed line. Eliminating the printed line saves the cost of ink to print the line and the web material where the line would be printed. 

A contrast is any visible printed, embossed or laminated feature on a web. Most of the time, a visible feature is understood to be visible with the naked eye. However, it can include UV printed features that are not visible to the naked eye, but are detectable for a UV type of sensor or camera.

CASE STUDY: Web Guide Upgrade Kit for Aging Web Guides

A major printer in the New England region had several web guiding systems with failing controllers, sensors and actuators. We were approached by their engineering department and we offered them the option of using upgrade kits with drop in actuators. This would allow them to keep the web guide mechanism and they would upgrade their sensor, controller and actuator to the latest technology in the industry.
