Ilfochrome (formerly known as Cibachrome) is a dye destruction positive-to-positive photographic process used for the reproduction of slides on photographic paper. The prints are made on a dimensionally stable polyester base, essentially a plastic base opposed to traditional paper base. Since it uses azo dyes on a polyester base, the print will not fade, discolor, or deteriorate for a long time. Characteristics of Ilfochrome prints are image clarity, color purity, as well as being an archival process able to produce critical accuracy to the original slide.
