Sick presents its PSS print detector, a device that combines pattern recognition and quality checking functions, making it a cost-effective solution for automated print quality control systems. The detector is even able to recognize printed images in poorly lit conditions, on round surfaces, and at speeds of up to 4 m/sec.

The main benefit of performing checks in this way is that any products featuring a defective print can be sorted out straight after the printing process has been completed. By providing on-the-spot information, the print detector also allows errors to be resolved quickly, avoiding any unnecessary machine downtime.

Sick’s PSS print detector recognizes patterns with the help of a sensor that verifies the presence of printed images, such as serial numbers, best-before dates, and 2D codes. The detector also confirms overall print quality by checking against its taught-in reference print. On a low sensitivity setting, the sensor will simply check that the required printed image is present, while on a higher setting, it can also check whether the image is too faint or incomplete.
