Duratrans

Duratrans were invented by Eastman Kodak Co. in the late 1970s and trademarked in 1982, to ascribe to their newly developed large-format backlit color transparency film, Kodak shortened the material name – Endura Transparency – to its current name. The original duratrans film was exposed photographically and developed chemically using a similar silver halide process as conventional lab photography.

Over time, the phrase duratrans has been genericized to apply to various large format backlit graphic substrates, imaged in a variety of ways including photochemical and various types of inkjets.
