The Plate-Chek offset plate densitometer measures dot area on plates. Its optical head automatically chooses the appropriate filter for the color of the images being read and with a specially designed optical head ensures accuracy.
Check dot gain on plates before they reach the pressroom? Yes.. .with a new offset plate densitometer, the Plate-Chek from Tobias. Lightweight and portable, the Plate-Chek features a unique optical head design that automatically selects the appropriate filter to read the plate image. The easy-to-use dot area functions enable you to determine the degree of dot gain on printing plates created by either direct-to-plate or conventional means of plate exposure. Evaluate exposure intensity, eliminate hot spots, check vacuum hold down with the Tobias Plate-Chek plate densitometer for precise QC dot gain evaluation.
