C-print

"C-print" stands for chromogenic colour print - a technique using silver-based chromogenic paper, which is light sensitive.

The C-print technique was originally developed in the 1950s by Kodak and was the standard colour photo printing technique until digital photography and inkjet printers took over. 

This technique became the new standard for photographic reproduction 
as they finally brought color into the medium. The photograph is created by exposing the paper with a light source and then processing it through a series of chemical baths, with critical attention to time and temperature – if the chemical is a degree too warm, or stays a second too long in the chemicals, the integrity of the print is lost.
