Jet Press 720S

Overview

Inkjet: The power to transform commercial print

Digital printing in the commercial print market has come a long way in the last twenty years, with toner based technologies having had the most success in delivering high quality, on demand print. Despite this success, however, the majority of commercial print is still produced using traditional offset presses.

Over the last six to seven years, inkjet deposition technology has evolved to such an extent that single pass printheads able to deposit ink at the speeds and quality levels required by the discerning consumers of commercial print have now become a commercial reality. It is these printheads, combined with sophisticated control systems, ink and paper handling technologies, that are now set to ignite a revolution in the way that commercial print is produced.

Jet Press development

Fujifilm has been at the forefront of these technology developments since 2004, with the company launching its first B2 inkjet digital press, the Jet Press 720, as a ‘technology announcement’ at Drupa 2008. This press became commercially available in 2011, with the last three years seeing installations all over the world. Now Fujifilm is launching its second generation press, the Jet Press 720S, with many improvements over the earlier model. The technology at the heart of these presses is SAMBA™, which is without doubt the industry’s most advanced single pass printhead technology. The development path of SAMBA™ has mirrored that of the press itself, with many improvements being introduced over the last eight years, the latest being the ability to replace individual SAMBA™ modules within a print bar.

Ready to transform your business

The world of commercial print is changing fast. Long run jobs are becoming more and more unprofitable as overcapacity in the market drives down prices. Print buyers, on the other hand, need the benefits that digital printing can bring now more than ever. Short runs, fast turnarounds and print-on-demand are all standard requirements in today’s fast moving world. And with ‘retro’ and ‘vintage’ being increasingly en vogue, there is a resurgence of interest in high quality, very short run print, particularly where the physical, emotional and tangible benefits of print can win over online information delivery.

These trends are set to continue at an even faster pace in the future, with the classic long run vs short run print model set to be turned on its head. This is where forward-thinking printers can prepare for the future and position their businesses to be at the forefront of these developments. B2 inkjet is the perfect technology to address these changing market conditions, and the Jet Press 720S is without doubt the front runner.

The efficient way to produce short run print

The most efficient way to produce short run print is to send the PDF to the press and print. This is how the Jet Press 720S operates, as this groundbreaking B2 inkjet press eliminates all the timely and costly preparation and set up parameters of an offset press. There are no plates to produce, no platesetters or processors to maintain, no make readies, no run up to colour, no waste sheets, and virtually no pressroom consumables.

The printed sheets can often be handled immediately (although drying time ultimately varies according to paper type), and print quality and consistency is guaranteed, with no on-press tweaks necessary. So if you are looking to be ultra-competitive on short run print jobs, the Jet Press 720S is about as efficient as you can get. Just send the PDF and print.

Components

A second generation press engineered to produce high quality print all day, every day

The Jet Press 720S has been built to produce high quality print all day, every day. The benefits of an offset paper handling system are obvious, and take advantage of technology that has evolved over many years to be ultra-reliable. But there are also many improvements in the Jet Press 720S detailed on this page that improve quality even further, improve variable data handling, speed up job downloads, reduce the necessity for system downtime and minimise breaks in production due to press maintenance.

Ultra-high capacity data servers

New high capacity data servers enable the press to download all the data needed to print a B2 sheet on the fly, making variable data and versioned print jobs possible on a single sided press.

1. Paper feed

Traditional sheet-fed paper feed mechanism　ensures high registration accuracy and reliable　operation.

2. Variable data scanning

To handle double sided variable data applications, a barcode is printed in the non-image area of every sheet. When the sheet is backed up, the barcode is read and the press downloads the right data for that sheet in the 1.3 seconds before printing.

3. Paper priming

The primer unit applies an ultra-thin film Rapid Coagulation Primer onto the paper via an anilox roller mechanism. The reaction of the primer and the water-based ink produces incredibly sharp dots and vibrant images on standard B2 coated paper.

4. SAMBA™ inkjet heads

The paper is fed onto the imaging cylinder where it is held by grippers and a vacuum, and four SAMBA™ print bars deposit the CMYK inks in a single pass. In the Jet Press 720S, the vacuum system has been further improved to enhance print consistency.

5. Sheet scanning

Every sheet is scanned by the In-Line Sensor (ILS) with the system making any necessary alterations in real time. In the Jet Press 720S, this system is mounted just after printing to ensure any adjustments are applied to the next printed sheet.

6. Infra-red paper drying

The Jet Press 720S features a new ink drying system, comprising infra-red lamps and Hot Air Knife (HAK) arranged across the B2 sheet width.

7. Paper cooling

Before the sheets leave the press, they pass under another bank of fans designed to optimise the sheet temperature and ink drying performance.

8. Sheet stacking

The final printed sheet emerges in the delivery area in the same way as a traditional offset press.
