Drupa 2012: Nanographic

The Nanographic? In one word: bye-bye offset printing!

This is the beginning of a totally new printing technology!

Landa Corporation announced during the international DRUPA fair in Dusseldorf the details of its groundbreaking Landa Nanographic PrintingTM Presses that are set to transform mainstream commercial, packaging and publishing markets. With output speeds comparable to offset presses and employing NanoInkTM colorants that create unprecedented image qualities, the Landa Nanographic PrintingTM Press portfolio is set to fundamentally change printing as we know it.

 

Some specifications for those of you who really want to know more:

Landa’s family of six Nanographic Printing presses – three sheetfed and three web presses – enable print providers to produce short-to-medium run lengths at unmatched cost-per-page.  Each of the three sheetfed presses can print in up to eight colours and can use spot and specialty colours for a range of applications including general commercial printing, marketing collaterals, medium-run books and manuals, direct mail and short-run folding cartons. The three web presses can print in up to eight colours and are aimed at commercial printing, publishing, labels, and flexible packaging.

 

The Nanographic Printing  Process

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.
