Over 13 years of experience in internal drum imaging has enabled
Heidelberg to develop the Prosetter range, a generation of violet
platesetters with outstanding quality and reliability. The internal
drum architecture delivers the precision that you have come to
expect from Heidelberg. In all the Prosetter models, the printing
plate is precisely aligned in a half shell and held in place by a
vacuum during imaging. The laser is moved along this half shell and
images the plate one dot at a time. The laser spot is guided via a
rotating prism, delivering precision down to thousandths of a
millimeter. This is made possible by the air bearing, which is
frictionless. Fitting the Prosetter with an SCL or MCL makes it
even more user-friendly and reliable. Operator intervention is
reduced to a minimum and you can produce nonstop for many hours.

"Two years ago, we purchased a Heidelberg Prosetter platesetter and
Printmaster four color press. That was our first experience with
Heidelberg and they have impressed us with their competence, depth
of knowledge and willingness to help. It's made us expect more from
our other vendors."
