Gum Printing with John Brewer

gum

Description

Gum bichromate is a late 19th-century photographic printing process based on the light sensitivity of bichromates (now called dichromates) with colloids, in this case gum arabic. It is capable of rendering both soft painterly images as well as finely detailed images from photographic/inkjet negatives. Gum printing is traditionally a multi-layered printing process building up density, but good results may be obtained from a single coating particularly if using a well crafted digital negative. Any colour can be used for gum printing, so full photographs are also possible by using this technique in multiple layers.

Students will learn how to make digital negatives using Photoshop and will then make gum prints from them.
