Converting Today. What is the main print technology used in Rexam, and what are the benefits?

摘要

Paul Wainwright: At Rexam, we use a dry, offset letterpress which has a number of advantages. Firstly, it is dry so no water is used or wasted. Because we use an offset process, we do not print directly on to the can, but rather on to a printing blanket that transfers the image to the can. This means there is a consistently clear and crisp image printed every time. In the offset letterpress, we use printing plates with raised areas to carry the ink from plate to blanket. This is similar to an old-fashioned typewriter key or potato printing, but done 2,000 times a minute with eight potatoes registered together to create an image.
