From Wikipedia, the free encyclopedia

Dye transfer is a continuous-tone color photographic printing process, popularized by the Eastman Kodak Company in the 1940s. It is sometimes referred to by such generic names as wash-off relief printing and dye imbibition printing. The process requires making three printing matrices (one for each subtractive primary color) which absorb dye in proportion to the density of a gelatin relief image. Successive placement of the dyed film matrices, one at a time, "transfers" each primary dye by physical contact from the matrix to a mordanted, gelatin-coated paper.

Eastman Kodak Company stopped making all materials for this process in 1994. The dyes used in the process are very spectrally pure compared to normal coupler-induced photographic dyes, with the exception of the Kodak cyan. The dyes have excellent light and dark fastness. The dye transfer process possesses a larger color gamut and tonal scale than any other process, including inkjet. Another important characteristic of dye transfer is that it allows the practitioner the highest degree of photographic control compared to any other photochemical color print process.
