While in Canada, Landa’s father devised a new camera using bicycle parts and pulleys that captured images directly onto photographic paper, avoiding the need for film.

[3] Landa studied physics and engineering at the Technion in Israel and psychology and literature at the Hebrew University of Jerusalem.

Applying the filmless imaging concept developed by his father, Landa founded Indigo Digital Printing in 1977.

The Indigo digital press uses an electric charge to apply small color particles (in liquid form known as ElectroInk), thereby creating a thin, smooth, plastic layer on the substrate.

Working with nanoparticles, Landa and his team sought to capture environmental heat from the surrounding air and convert it into electricity.

These units eject the ink droplets onto an intermediate belt, which in turn deposits the resulting image onto paper.

Landa's technology is intended for production of short-to-medium run lengths (up to 5000 prints), either on cut sheets or roll-fed paper.

[10] The long-term reliability and cost-effectiveness of the process (including the typical inkjet concerns of printing-head longevity and nozzle clogging), as well as the long-term environmental impact (including the polymer-based ink as well as the nanotoxicological concerns engendered as a direct result of the minimal physical sizes of the particles themselves during manufacture, use, and disposal), are still to be determined.

The Landa Fund also supports non-profit organizations in the fields of education and promoting tolerance and understanding between Israel’s Jewish and Arab citizens.
