A viable digital rival to B2 litho offset presses.

What does it do?
This is claimed to be the fastest B2 format sheetfed digital press in the market. It’s a single-pass inkjet, printing wide-gamut CMYK onto standard offset papers and carton board. It succeeds the Jet Press 720S introduced in 2014, with 33% faster speed, more uptime, greater stock range and a new food-safe ink option. It also has a new black colour scheme.

When was it announced and what’s the target market?
First announcement was at IGAS in Japan last September, followed by Europe in November. According to Mark Stephenson, product manager for Fujifilm Graphic Products Europe, Jet Press 750S is aimed at the same short-run, high-value markets as the 720S, but its higher speeds and greater uptime mean it’s a viable competitor to B2 litho presses with LED curing.

How does it work?
As with the previous models, the Jet Press 750S is based on an RMGT (Ryobi) offset chassis. This has a standard offset feeder, side lays, grippers and delivery to avoid the common digital press problem of print drifting from sheet to sheet.

The print bars have new high speed versions of the Fujifilm Dimatix Samba piezo heads. They run at 33kHz, up from 25kHz on the 720S. A built-in scanner monitors quality and detects blocked jets, with on-the-fly compensation. Cleaning routines take three minutes every two hours and can be easily completed between jobs.

The faster speed required an all-new drying system with a heated vacuum belt to stabilise the sheets. The previous hot air and IR system is replaced by IR only, saving 23% of electricity use. The vacuum belt also extends the paper range. “We can get down to 80 or 90gsm now depending on ink coverage,” says Stephenson. “It’s always the same speed and quality on any stock.”
As before, this is a simplex press, with a barcode reader to ensure the correct image and position on the reverse side. Stephenson reckons that potential customers will often have non-perfecting B2 offset presses already.

The sheet size is increased a little, though this allows six US Letter sized pages to fit, but not six A4s. “It does mean you’ll get more small items such as business cards on a sheet,” Stephenson points out.

Fujifilm Vividia aqueous inks are carried over from the 720S. Fuji claims that these can match 90% of standard Pantone PMS colours. Complementing this is a new Cloud service called XMF ColorPath Brand Color Optimizer, which can profile all 1,872 Pantone colours for any stock.

There’s an option to run a new food-safe ink for packaging, at a slightly higher cost. This has a slightly reduced gamut too.

What’s the USP?
“It’s the best of both worlds between offset and digital,” says Stephenson. “It has offset feeders, side lays and grippers, so there’s registration accuracy, as well as uptime. But it also has fast turnaround, with no plates, no make-ready and a wide gamut.”

Ease of use?
It’s a highly computerized press, but Stephenson says there’s more to using it than a £30,000 office printer. “You don’t just throw paper in a drawer and press the green button,” he says. “You need to learn about the paper handling, which is the same as an offset press. But we get offset operators coming to the showroom and opening the gate every few minutes until they realize that the quality is the same across the run. It’s also boringly reliable!”

What support and training is on offer?
Fujifilm provides a standard maintenance contract. Application training is usually done on site.
