Dye-Transfer prints
Dye transfer is a continuous-tone color photographic printing process. In the 1940s, this process was popularized by Eastman Kodak for general-purpose graphic arts work.
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.
