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.
