Release print

A release print is a copy of a film that is provided to a movie theater for exhibition.

Release prints are not to be confused with other types of print used in the photochemical post-production process:

In the traditional photochemical post-production workflow, release prints are usually copies, made using a high-speed continuous contact printer, of an internegative (sometimes referred to as a 'dupe negative'), which in turn is a copy of an interpositive (these were sometimes referred to as 'lavender prints' in the past), which in turn is a copy, optically printed to incorporate special effects, fades, etc., from the cut camera negative. In short, a typical release print is three generations removed from the cut camera negative.

The post-production of many feature films is now carried out using a digital intermediate workflow, in which the uncut camera negative is scanned, editing and other post-production functions are carried out using computers, and an internegative is burnt out to film, from which the release prints are struck in the normal way. This procedure eliminates at least one generation of analogue duplication and usually results in a significant higher quality of release prints. It has the further advantage that a Digital Cinema Package can be produced as the final output in addition to or instead of film prints, meaning that a single post-production workflow can produce all the required distribution media.

As of March 2015, Eastman Kodak is the only remaining manufacturer of colour release print in the world. Along with Kodak, ORWO of Germany also sells black-and-white print stock. Other manufacturers, principally DuPont of the United States, Fujifilm of Japan (the penultimate company to discontinue colour print stock), Agfa-Gevaert of Germany, Ilford of the United Kingdom and Tasma of the Soviet Union competed with Kodak in the print stock market throughout most of the twentieth century.
