The Truepress Jet 520HD inkjet web press is a 20-inch production-class printer for the commercial print, direct mail, and publishing markets. It can deliver offset quality printing (1200 x 1200 dpi) and has a top-end printing speed of almost 400 feet per minute. What really sets it apart, however, is that specially-developed Screen ink gives 520HD owners the ability to print on the same coated litho stocks they currently use on their offset presses, without pretreatment or primer. Customers confirmed the breakthrough.

Continuous feed inkjet print engines have achieved print speeds and throughput capacities that begin to rival conventional offset presses. However, achievable image quality and the limitations of printing to uncoated stocks--or a requirement to print to premium or treatedfor- inkjet stocks when coated papers were required-- has limited the ability and economic feasibility of the technology to reach beyond transactional mail, lower quality direct mail, and applications that do not require coated stocks such as book publishing. The cost savings from printing on commodity-grade papers and not having to warehouse different stocks for offset and inkjet are significant.

The image quality achievable by the Truepress Jet 520HD and the paper addressability of the proprietary Screen Truepress SC ink opens continuous feed inkjet to a new variety of applications, replacing both conventional offset work as well as that produced on toner-based presses. The thin film of the SC ink allows for the characteristics of the paper to perform as designed, whereas the high pigment load results in the ability to produce sufficient ink densities with low total area coverage, resulting in drying efficiencies, improved press performance, and ink savings.

The image quality and speed comes from using a 1200 1200 dpi print resolution and multi-level droplets, a new color management system, faster drying due to high pigment ink, and a RIP that can that can send variable data to the press in milliseconds.
