 Technicolor continued to offer its proprietary imbibition dye-transfer printing process for projection prints until 1975, and even briefly revived it in 1998.As an archival format, Technicolor prints are one of the most stable color print processes yet created, and prints properly cared for are estimated to retain their color for centuries.With the introduction of Eastmancolor low-fade positive print (LPP) films, properly stored (at 45 °F or 7 °C and 25 percent relative humidity) monopack color film is expected to last, with no fading, a comparative amount of time.
