There’s one more announcement from DRUPA (the 2012 edition of the International Trade Fair for prepress, premedia, printing, book binding, print finishing and paper converting held May 3 – 16, 2012) that I want to feature here, especially since it’s nanotechnology-related. From the May 17, 2012 news item on Nanowerk,
Landa Corporation announced the details of its groundbreaking Landa Nanographic Printing™ Presses that are set to transform mainstream commercial, packaging and publishing markets. With output speeds comparable to offset presses and employing NanoInk™ colorants that create unprecedented image qualities, the Landa Nanographic Printing™ Press portfolio is set to fundamentally change printing as we know it.
Landa Founder, Chairman and CEO Benny Landa says, “Nanography™ is a new technology for applying ink to paper. In developing Landa Nanographic Printing we had to re-think and reinvent the printing press. The result is digital printing with remarkable performance – from a family of presses that share stunning ergonomic design, a small footprint and some of the most advanced user functionality available in the market.”
There is very little technical detail which is typical of Landa’s approach. As I recall from my days working for a competitor, Indigo, Landa’s last printing company, sold presses built on proprietary software. Any printer who purchased Indigo products was locked into the ‘Indigo world’ as there was no possibility of mixing and matching products from other manufacturers.
On that note, I notice this reference to a propriety ink in Landa’s latest product announcement (May 17, 2012 news item),
At the heart of the Nanographic Printing™ process are Landa NanoInk™ colorants. Comprised of pigment particles only tens of nanometres in size (1 nanometer is about 100,000 times thinner than a human hair), these nano-pigments are extremely powerful absorbers of light and enable unprecedented image qualities. Landa Nanographic Printing is characterised by ultra-sharp dots of extremely high uniformity, high gloss fidelity and the broadest colour gamut of any four-colour printing process.
Nanographic Printing begins with the ejection of billions of microscopic droplets of water-based Landa NanoInk onto a heated blanket conveyor belt. Each droplet of aqueous NanoInk lands at a precise location on the belt, creating the colour image. As the water evaporates, the ink becomes an ultra-thin dry polymeric film, less than half the thickness of offset images.
The resulting image is then transferred to any kind of ordinary paper, coated or uncoated, or onto any plastic packaging film – without requiring pre-treatment. The NanoInk film image instantaneously bonds to the surface, forming a tough, abrasion-resistant laminated layer without leaving any residual ink on the blanket.
Since NanoInk images are already dry, there is no need for post drying. Two-sided printing becomes simple and printed goods can be immediately handled, right off the press, even in the most aggressive finishing equipment.
Given that the printing industry is not experiencing growth these days, it’ll be interesting to see if this ‘nano’ approach is going to work. My last posting about the 2012 DRUPA focused on 3-D printing and paper loudspeakers (May 4, 2012).
