Screen Announces Truepress Jet520HD


Screen announces the next generation of inkjet printing with the launch of the Truepress Jet520HD.

Screen has manufactured more than 700 inkjet presses since the market-defining Truepress Jet520 was originally launched and it remains today the best-selling inkjet press for the transactional, direct mail and book printing markets.

Despite this success, Screen has recognised that the market for inkjet can be extended by offering a significant improvement in print quality and by widening the range of materials that can be printed.

Screen set about developing a next-generation inkjet printing machine where quality is the driving force. The result is the new Truepress Jet520HD, a ground-up design with new paper transport, new drying techniques, new printheads and new screening technologies that make the most of new wide-gamut inks.

Starting with the basic specifications, like many of the current inkjet machines on the market today, this new model is 520mm wide but there the similarities end. The first big difference is the combination of speeds and resolutions. The highest quality output is achieved at 50m/min with a resolution of 1200x1200dpi while the fastest speed is 120m/min at a resolution of 600x600dpi.

In addition to the high resolution, the Truepress Jet520HD benefits from the printhead’s ability to produce variable size droplets. In combination with the company’s unique screening algorithms, different size droplets can be precisely placed to maximise print quality and minimise ink consumption.

The next key difference is a new high density ink which is very close to the standards used in offset printing worldwide. Using ink with such a high density allows the operator to choose between printing with the highest quality or to minimise costs by using less ink than current inkjet technologies.

Most inkjet web presses today can only print on a limited range of substrates, typically 60gsm to 170gsm. The new Truepress Jet520HD can print on material from 40gsm to 250gsm which significantly increases the flexibility of the machine in terms of the work that can be produced. Printing high-quality variable colour on 250gsm board creates many new direct mail opportunities such as post cards and one-piece mailers.

While the initial machines will be launched as four-colour units, the Truepress Jet520HD has a modular structure to allow for extra head units to be added in the future. Each printhead will be controlled independently so that if you are only printing with one colour, all of the other printheads remain capped. However, there is no time delay when switching from a single-colour to multi-colour job.

All Screen’s inkjet printers have a reputation for their ease of use and simple maintenance routines, and this has led many users to opt for a self-service approach. The Truepress Jet520HD will be no exception. For example, the use of industrial printheads means that head changing is not a regular event and even when they do need to be changed, the unit is easily accessible and changing a head is simple.

The Truepress Jet520HD will be launched with an optional inspection unit based on Screen’s highly regarded JetInspection. JetInspection is a system that checks the whole page and compares the printed result to the RIP data to give a unique level of security. JetInspection has been redesigned for use with the new press, including complete integration with the machine’s GUI.

Last but not least, the Truepress Jet520HD benefits from being driven by Screen’s Equios workflow software. A new version of Equios will be launched with the printer that has new features to optimise the machine’s performance such as In-RIP Smart Imposition, ICC Profile Editor and Spot Colour Editor. Using the latest Adobe core, Equios will be able to process all levels of variable data at the full engine speed.

Because the focus of the development for the Truepress Jet520HD has been on increasing the market applications for high-speed inkjet, the new machine will not replace the current family of Truepress Jet520s. The Truepress Jet520 still offers excellent value. Similarly, Screen will continue to sell the Truepress Jet520EX Mono for black and white printing for the higher speeds required in some volume applications as well as the Truepress Jet520ZZ that delivers up to 220m/min.
