Fujifilm has announced its third generation B2 inkjet press, the Jet Press 750S. With higher productivity of 3,600 B2 sheets per hour, the Jet Press 750S is now the fastest, full colour, B2 sheet-fed digital press on the market.
The target market for this press is likely to be those looking to produce print runs up to 5,000, allowing it to compete with, and out-perform, offset presses in the production of high quality, short run print jobs. This makes it an ideal investment for a much larger range of commercial and packaging printers.
The company says that printing on paper moving at the higher speed of 3,600 sheets per hour requires a corresponding speed upgrade to the number of ink droplets deposited per second. The jetting frequency of the new generation Samba printheads in the 750S has therefore been increased from 25 kHz to 33 kHz to speed up dot placement and counteract the increased effects of possible turbulence. It also has the additional benefit of reducing dot placement variations, therefore improving quality.
A completely new drying system has been introduced to increase speed and efficiency, in which a printed sheet is passed onto a transfer belt heated via rollers, with a vacuum applied as the sheet passes through the drying section to keep it dimensionally stable. Drying is carried out via a combination of the heated belt and hot air applied from above. As well as operating at higher speeds, this new system allows greater control and fine-tuning of temperatures, extending the range of substrates that can be printed.
Fujifilm says that around a third of all current European Jet Press customers already produce some form of packaging on the press. With its 33% speed boost and variable data printing at full speed, the new Jet Press 750S is ideally suited to printing versioned and short run packaging to coincide with specific events, localities or store promotions.
The introduction of the Jet Press 750S is likely to accelerate this trend. It can be modified to accommodate heavier weight folding carton stock (up to 0.6mm in thickness), and printed sheets from the press have been tested and found to be compatible with a wide range of analogue and digital coating, foiling, lamination and cutting solutions. An automatic bridge is also available to connect to online coating solutions.
Customers in Germany and Portugal have already signed-up for the new Jet Press 750S. Mediadruckwerk in Hamberg, and FloriColor in Porto will both be taking delivery of the new press in early 2019.
