LIST - Line Scan Technology

Standard printers use a conventional area camera and prisms for alignment and use the same camera to rapidly shoot many small field-of-view pictures for inspection. ERSA revolutionizes these processes via the use of a line sensor based camera for both alignment and inspection. Similar to a standard scanner, the LIST camera (patent pending) has top and bottom line sensors at a resolution never before seen in a scanner. Standard cameras take many pictures of a very small area, whereby the LIST camera scans the entire length of 260mm at a speed of 35mm per second. The fastest inspection speed in a printer today is 1,200 mm2. The LIST camera in the VERSAPRINT achieves the world's fastest inspection speed of 9,100 mm2. In addition to inspection speed, the scanning of the entire substrate offers additional advantages with respect to no stretching and the teaching in of fiducial marks.
