  • PLATE HANDLING WITH THERMAL TENSIONING
    Publication number: 20050039315
    Abstract: Printing plates are mounted onto a cylinder by first establishing a temperature difference between the plate and the cylinder; in particular, the temperature of the plate exceeds the temperature of the cylinder. The plate is then wrapped around the plate cylinder, and the temperature difference causes the plate to shrink against the cylinder.
