Landa Corporation on Monday claimed a major breakthrough in digital printing, based on nanotechnology.

Benny Landa's company announced what it called an entirely new printing category. The process uses tiny pigment water-based particles that are only tens of nanometers in size (a human hair is about 100,000 nanometers wide ), and can print on almost any material.

"Landa is now set to ignite the second digital revolution in print. Landa Nanographic Printing Presses offer the versatility of digital with the qualities and speed of offset printing," the company claimed.

The technology will be unveiled officially at the Drupa print media fair in Dusseldorf at the beginning of May.

"It's good to be back," said Landa, 65, who founded the Indigo printing firm, which he sold to HP in 2001 for $830 million. He founded Landa Corp. in 2002 to specialize in nanotechnology. "The Landa printing process is the result of ten years of nanotechnology research. It is a true breakthrough that enables our presses to achieve amazing results," he added.

Landa has financed the private firm entirely out of his own pocket.

The company called its new process "eco-friendly and energy-efficient," and said it would produce the lowest cost-per-page digital images in the industry. Each press can print in up to eight colors and operate at 600 dpi or 1200 dpi resolution, at speeds up to 11,000 sheets per hour.
