Duratrans
From Wikipedia, the free encyclopedia
Duratrans were invented by Eastman Kodak Co. in the late 1970s and trademarked[1] 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.
The most common usage of duratrans is for the backlit graphic film used for promotional advertising displays in shopping malls, airports, casinos, movie theaters, restaurants, retail stores, trade show exhibit halls and any retail establishment that contains any number of backlit display lightboxes in which the printed duratrans graphic films must be inserted and illuminated, in order to gain the advantage of their backlightable property.
Promotional duratrans are imaged with advertising messages, product and lifestyle photos, informational and/or menu content, and/or virtually any printed content the user desires to display.
"Fine Art" duratrans
The distinction between promotional and fine art duratrans is purely in the subject matter of the artwork imaged onto the duratrans film. There is no other defining difference, except that possibly a fine art duratrans may be processed using higher resolutions, color depths, and/or other fabrication tolerances to effect a higher-precision result, for a more-demanding audience.
