What does the machine do?
Bound to be one of the stars of Komori’s Drupa stand when it launches in June, the Impremia NS40 is a new B1-format digital sheetfed press that licenses Landa’s Nanography process.
Robert Holscher, sales director digital & finishing equipment at Komori International Europe, emphasises completely separate development to Landa’s own B1 S10 press: “I compare it to Formula One racing teams, where everyone may have the same engine, but one will drive faster because they have fine-tuned the chassis, the suspension and everything else.”
When was it launched and what market is it aimed at?
Komori partnered with Landa and made components for Landa’s Drupa 2012 show presses as well as starting its own licensed development. An early NS40 was demonstrated at Drupa 2016. The commercial launch will be at Drupa 2020 in June.
Initially the NS40 will have a simplex configuration for the packaging market. The inline coater will run aqueous or UV fluid. An optional double delivery for pharmaceutical work will automatically detect and divert rejected sheets.
A commercial beta test site at Shinwa Manufacturing Co in Kawagoe City, close to Tokyo, was announced late last year. This has mainly been using it for POS work on board and paper, and samples will be shown at Drupa.
How does it work?
Impremia NS40 uses a licensed Nanography print engine with Landa-supplied NanoInk. This is an offset process, with piezo inkjets building up the full-colour image on a silicon rubber blanket on a heated transfer belt. This evaporates water from the ink to leave a sticky resin-pigment layer that is then transferred completely to the substrate. As the belt returns through its loop it passes through a cleaning unit that removes paper dust and applies a “soapy water” that equalises the temperature and acts as a wetting solution to stop aqueous ink from beading on the hydrophobic surface on the next ink application.
This dry transfer process makes it possible to use a very wide range of paper and plastic substrates in weights from 0.06 to 0.8mm, including standard litho stocks, or uncoated and quite rough grades.
NanoInk uses minute 10-nanometre pigment particles, said to give extremely good colour saturation and gamut. “With seven colours you can get a Pantone range of 96% and with four colours it is 84%,” says Holscher.
The NS40 chassis, substrate transport and control systems are adapted from Komori’s Lithrone B1 litho press technology. The digital front-end and closed-loop colour management are adapted from Komori’s B2 Impremia IS29 UV inkjet press (developed with Konica Minolta which calls it AccurioJet KM-1). The NS40 will integrate into Komori’s KP-Connect pressroom network.
How productive is it? 
Holscher says for quality reasons the top speed will be 6,500sph initially with fully variable data, although the engine can reach 13,000sph. “We’ve done a lot of extra development with regards to reliability, productivity, belt lifetime and so on.”
What is the USP of the product?
It’s a B1 digital press with the attributes of Nanography – good print quality, bright colours, respectable speed and predicted low costs per copy – plus Komori’s developments for reliability and cross-compatibility with its litho presses.
How easy is it to use?
For operators, NS40 has a lot in common with Lithrone litho presses and IS29 digital presses, says Holscher. “You don’t need to put in plates and the RIP takes care of colour management. The operator just has to find the right job, put in the paper and print.”
