Plate-Chek  Precise measurement of printing plate dot area. Used with either computer-to-plate or conventional plate exposure systems, the Plate-Chek is a specialised densitometer for measuring dot area on plates during prepress. This makes it possible to evaluate exposure intensities, eliminate hot spots, calibrate the intensities, eliminate hot spots, calibrate the platestter and verify the operation of its vaccum hold-down. Lightweight and postable, the Plate-Chek automatically selects the best colour response for maximum sensitivity in reading the plate inage, and its sophisticated
