High Speeds Print Quality Inspection System

Many printed products (currency, tickets, commercial publications, newspaper, pharmaceutical and food packaging, and more) require 100% print inspection (often in color) as part of their quality control process.


Speed is everything in the printing industry: Newspaper and magazine printers move printed pages along at up to 100 km/h. If you examine a color printed image, then color fidelity is an important element for the system's cameras. Beyond this, high sensitivity in the camera and the ability to handle high speeds is essential for precise and reliable examination of webbed materials for flaws in paper, wood, textile, glass and similar materials.


From paper to cardboard, plastic or metal, in continuous webs or sheets, print inspection applications are well suited to line scan systems. Line scanning offers unlimited pixels in the direction of a web's motion with zero smear even at high speeds, higher dynamic range, greater processing efficiency and much lower price/pixel. 

Contrastech’s line scan systems provide higher resolution with fewer cameras and inspect 100% of a moving surface without smear or the need to process frame overlaps.
