dye transfer process
n.
A photomechanical process to make prints from photographs by creating a gelatin relief matrix that is used to transfer dye to an emulsion on paper.
Notes
The depth of the matrix is relative to the density of the image, with areas of greater density able to transfer a greater amount of dye. A single matrix produces a monochrome print, although separation negatives can be used to create several matrices, each of which is printed in registration using a different dye to produce a full-color image.
