Inkjet sheetfed print systems – the runners
If drupa had taken place, there would have been almost as many
B2 and above sheetfed inkjet print systems on show as offset.
Print21 looks at the emerging players in what is sure to be a growing sector.
Konica Minolta KM-1e
Konica Minolta has launched a new version of its B2 inkjet sheetfed printer, the AccurioJet KM-1e. Tatjana Ferguson, Industrial
Print product marketing manager
at Konica Minolta, says the new version has several updated features including “a new sensor for expanded substrate capability including Metallic, PET, PP, Coloured Paper, and clear plastic and film”.
It also has new printheads that improve image quality and reduce ‘jet-outs’, an improved workflow with option to connect to third party vendors for post-press finishing, a new inkjet manager that supports VDP PPML formats, and a tape Inserter option for slip-sheet applications. It also has shorter, streamlined maintenance and printhead replacement times, less downtime between print jobs, and CSRC remote inspection capability.
Adam Todd, Konica Minolta Industrial Print Specialist, said “Feedback from our customers is that the AccurioJet KM-1e allows them to produce a much wider gamut of printed applications, on a wider variety of stocks and more cost effectively”.
Todd added “Being a UV Inkjet press the KM-1e can print on just about
Fujifilm Jetpress 750S
The Fuji Jetpress 750S that succeeded the original Jetpress
720S has an increased sheet size and numerous changes to increase its appeal as a productive printing press.
The press is faster, thanks to running the latest version of the Samba printhead, reaching 3,600iph, which the company says makes it
the fastest four-colour B2 digital cut sheet press on the market. Fujifilm says the inks offer a wider gamut than a standard offset four colour, achieving 90 per cent of the Pantone colour library.
It is more consistent thanks to improved scanning for errors, colour management and consistency. And it is more productive due to an extension of the printhead cleaning cycle to two hours, and a nozzle purge routine which begins as the head arrays moving to the cleaning station. The press is single-sided, using barcodes to match the reverse with the first side printed for variable data work.
The inks conform to European packaging standards for products. Fuji claims the press is a first to meet all European food safe regulations. 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.
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 through the press is compensated for in software.
Fujifilm is still producing the Jetpress 720S for those not needing the additional size nor the features that meet requirements of packaging where repeat runs are the norm.
Fujifilm says the new JetPress 750S will be aimed at medium run
as well as short run work, and is designed for industrial 24 hour-a-day production.
A new high speed version the 750HS will be available early next year, which adds 50 per cent to the output rate, printing up to 5,400 B2 sheets per hour.
