Then, exposed crystals catalyze the oxidation of developers which in turn couple with dye precursors to form the image dyes. Kodak also is developing novel support media , which impart new optical viewing characteristics as well as new levels of pictorial durability. Our new Duralife Color Paper will remain stable for 200 years in albums, and for up to 125 years in home display situations. It also resists tearing and curling. Increasingly, this technology is also used as output media for digital cameras.
Thermal printing yields high-quality images.
This offers a greater dynamic range of density than conventional silver halide photography. Often a clear protective laminate is applied to the receiver in the printer to protect the image from fingerprints, plasticizers in photo albums, and liquid spills. This laminate greatly improves the durability of thermal prints. A thin plastic ribbon is coated with patches of cyan, magenta, and yellow dyes dissolved in polymers. Then, in a printer, a computer-controlled thermal head applies heat to the back of the ribbon.
