Gum Dichromate is a 19th Century photographic contact printing process in which the image is formed on a coating of sensitized gum containing pigment. It is capable of rendering painterly images from photographic negatives. This historical method is quite versatile in nature and could be manipulated according to the artist’s need.
The gum Dichromate process, like much photomechanical printing, depends upon the reaction when a dichromate salt is mixed with an organic colloid, e.g. gum or gelatin, that reaction is speeded up when the mixture is exposed to UV light. Exposure to UV light makes the mixture insoluble to water hence when the exposed paper is developed in water the pigmented shadows remain while the highlights are washed clean.
