Small increase in format as Jetpress gains extra maturity

The Fuji Jetpress 750 has an increased sheet size and numerous changes to increase its appeal as a productive printing press.

Fujifilm is launching the Jetpress 750 that was introduced at Igas in September across the world. The format is marginally larger than the Jetpress 720S, but is enough to print six-up American letter size pages, though not large enough for six A4s.

This though is not the main attraction, at least not outside the US. The press is faster, thanks to running the latest version of the Samba printhead, reaching 3,600iph.

This makes it the fastest four-colour B2 digital cut sheet press on the market, says Mark Stephenson, Jepress product marketing manager. And it is only a four-colour machine, albeit that the inks offer a wider gamut than a standard offset four colour, achieving 90% of the Pantone colour library.

It is more consistent thanks to improved scanning for errors, colour management and consistency. And it is more productive thanks to extending the printhead cleaning cycle to two hours and a nozzle purge routine which begins as the head arrays to moving to the cleaning station. Uptime, says Stephenson, is around 90%. The press remains a single-sided machine using barcodes to match the reverse with the first side printed for variable data work.

And Fujifilm is taking a second tilt at the carton market with the new machine. The first carton version of the press failed to convince European buyers. Now the inks, and what other consumables there are, conform to European standards for products in the ink and coating. Fuji claims the press is a first to meet all European food safe regulations including the Swiss Ordinance regulations. The ink is developed in the UK and produced in Broadstairs.

The carton target includes sheet handling to 600 micron thickness, an upgrade to the XMF workflow to deliver four-colour matches for spot colours separated from the normal four-colour workflow. The press has an optional scanning head to offer a precise match to a pass sheet for both content and colour.

There is a matched Harris & Bruno coater, running offline currently, but potential directly inline via a bridge and nesting software from Tilia Labs to impose carton blanks on the sheet.

The Jetpress 720S remains available for those not needing the additional format nor the features that meet requirements of packaging where repeat runs frequent rather than the bespoke nature of commercial print. It will also be priced below the new flagship.

A new dryer in the Jetpress 750 includes a heated belt to dry from below while hot air removes water from the ink before cooling. Any distortion of the sheet on the first run though the press is compensated for in software.

The 33% hike in productivity opens up longer runs than made sense previously. “We have opened up a new zone for digital presses, beyond the limit of toner towards bigger jobs,” says Taro Aoki, head of digital press solution, Fujifilm EMEA. To date Fujifilm has installed 150 B2 inkjet presses, 70 in Japan and 40 each in North America and Europe.

“We want to get away from the print on demand market, where machines can be lightweight and cannot run all day. They are not designed for 24 hour running and the Jetpress is,” Stephenson says. “We can start to tackle more medium run work.”

The Jetpress 750 offers more than an upgrade to its format, including features that will appeal to carton printers.
