Delivers higher print speeds on coated litho stocks, expands lightweight paper capabilities, fine-tunes drying performance across all substrates used for commercial-grade digital inkjet print.
SCREEN’s flagship, high-volume production inkjet web press has made another leap toward, becoming the preferred technology for printers looking for offset-quality on standard stocks, using inkjet technology.
“When we introduced the 520HD press a little over two years ago, the market was surprised by its offset-like image quality,” says Peter Scott, managing director of Screen GP Australia. “It was the first time high speed inkjet demonstrated the capability for effectively printing jobs that approached offset quality. Development has been on-going since that time, with the SC inks being the most significant advancement.
“Drying and curing is always an issue with high-volume inkjet, there’s a lot of water to get rid of, and now with the new Near Infrared (NIR) Dryer, we can achieve what no other digital inkjet press does. NIR technology dramatically advances productivity for work demanding high image quality and expands print applications for high speed inkjet across a broad landscape of products.”
The new SCREEN NIR Dryer technology, built into the existing press frame of the 520 HD, extends drying performance for both lightweight uncoated stocks and heavier weight, coated litho substrates. The result is an expanded range of applications and even higher productivity on difficult to dry substrates.
Drying on the 520HD is now 3-tiered: heat dissipation, hot air assist, and new infrared. This integrated solution achieves a drying balance along the entire paper path tuned specifically to the characteristics of the paper, reducing or eliminating the cockling often associated with traditional inkjet ink drying methods.
Intelligent drying
Operators create substrate profiles with embedded drying protocols at different print resolutions and ink limits. These profiles are managed seamlessly by Screen’s proprietary Equios front end software, providing intelligent drying balance for each specific stock helping achieve the highest quality, best speeds and desired ink coverages.
Scott adds: “All new Screen Truepress Jet 520HD machines may be optionally equipped at the factory with the NIR dryer. Screen branded 520HD units currently in the field can be upgraded with the new dryer at the machine site. It’s a major move forward in making production web inkjet a viable alternative to offset – with all of the benefits of no plates, short runs, variable data, offset stocks and streamlined digital workflow.”
