Diavography
Diavography is the name of a fine printing process . The GEO photographer Heinz Teufel was one of the inventors of this technology in 1997 and the name giver (“Diavolo” = Italian for “devil”).
In order to produce diavographs, special digital color printers are required that hold the color particles through electrostatic charging. A so-called "data carrier" takes on highly lightfast color pigments in a higher density than paper, there is no print raster.
Then the data carrier is printed directly from the data carrier onto hand-made paper under high pressure . This creates a UV-stable, scratch-resistant and chemical-resistant surface.
The durability of the prints is certified for 50 years. The dark shelf life should be over 100 years.
The Frankfurter Allgemeine Zeitung described the diavography as a “perfect art print process”.
