Paper fold recognition in printing machines

The paper printing technology has a lot of physical and chemical processes going on during paper production that needs to be well coordinated considering the speed with which books and newspapers are printed. This high-speed production often results in folds produced in the paper web that affects the production process. Sometimes, extreme differences in printing registration occur such as inaccuracies when correlating overlapping colours or the paper web tears while going through the print machine, which often lead to unusable printed product.

To prevent such incidents from occurring, optical measurement technology is considered ideal for use in inline production. The scanCONTROL laser scanner by Bestech Australia provides a non-contact measurement that recognises paper folds during production and measure them. This scanner matches the production speed just fine and gives precise results in high-speed operations.

The laser scanners are available in different classes (Compact, Highspeed and Smart) to suit a vareity of user requirements. They can be easily integrated into an existing customer software either via the available SDKs or the GigE Vision Standard. Their compactness and high profile frequency makes them ideal for dynamic measurement tasks.
