Process-Color Pad Printing
|
From Pad Print Machinery of Vermont
As with most methods of reproducing process-color images, the creation of near-photographic quality separates the novices from the experts. Process-color pad printing has been practiced for many years and came of age when photographic images first saw use in CD printing, before the introduction of today's high-speed multipolar screen-printing presses. At that time the output requirements were much less, with 500 discs/hr being acceptable. A pad-printed line ruling of 175 lines per inch allowed a tonal range of 5- 95%, which was printed on a gloss white background, and the printed results were superb. Admittedly some of the designs were pretty wild, their designers having resorted to something stronger than Earl Grey tea before their creative sessions. But this was the pinnacle of multipolar pad printing and arguably the best quality direct CD printing ever achieved. Products & Services
