At Indian Rock Imagesetting,we have designed our digital printing system around the Heidelberg Quickmaster DI, a four-unit waterless offset printing press. There is no film used in this process; the plates are imaged directly on the press by sixteen high speed lasers in each color unit. Because of the short "make-ready" for the DI, Indian Rock can offer exceptionally fast service and Heidelberg four-color quality printing for short runs, at very competitive prices.
