Fujifilm has officially launched its Jet Press 750S, which I’ve already covered earlier this summer after a prototype was shown at the Tokyo Igas show.
It’s based on the existing 720S B2 inkjet press but takes a larger 750mm x 585mm sheet size (the 720S prints to 750mm x 532mm sheets).The 750S uses the latest generation Samba printhead, with the jetting frequency increasedfrom 25 kHz to 33 kHz, which contributes to a faster speed of 3,600 sheets per hour. There’s a completely new drying system, with the printed sheets passed onto a transfer belt heated via rollers and held in place by a vacuum to retain their dimensional stability. The drying itself is carried out via a combination of the heated belt and hot air applied from above, which allows for better control and fine-tuning of temperatures, extending the range of substrates that can be printed.
There’s a new automated head cleaning process, called Overflow Cleaning, which carries out head cleaning at times when the press is between jobs or the printhead assembly is in motion.It’s also fitted with a new Active Head Retraction (AHR) system which lifts the print bars from the drum when a paper deformation is detected (<3mm), reducing the likelihood of paper jams caused by damaged paper. The 750S also gains a new optional ImageConfidence scanning system, in addition to the In-Line Scanning (ILS) system used on the 720S, which uses a proprietary AI algorithm to evaluate the full print area of a B2 sheet on-the-fly, ensuring every sheet matches a pre-approved image.
The 750S is 33 percent faster than the older 720S. Fujifilm says that its designed to compete against offset presses, claiming that it is likely to be highly competitive for print runs up to 5,000, depending on ink coverage. In addition, it can be modified to take heavier weight folding carton stock up to 0.6mm in thickness, making it suitable for some short run packaging applications. Fujifilm says that it has successfully tested printed sheets on a wide range of analogue and digital coating, foiling, lamination and cutting solutions. There’s even an automatic bridge available to connect to online coating solutions.There’s also an option to use a low migration ink, which I’ve also covered earlier here.
Amongst the first European customers for the 750S will be Mediadruckwerk, based near Hamburg in Germany, and FloriColor, based in Porto in Portugal.
