Dye-transfer print
A type of colour print made by a series of related processes in which three carefully superimposed layers of dye are transferred to a gelatin-coated base. The dye-transfer process, which has come a long way since its origins in the 1870s, is time-consuming but permits a lot of control of results and produces a relatively permanent print that does not contain silver.
