Gum prints
Gum dichromate printing is the technique most responsible for the current revival of the historical
processes. Gum prints can be made in any color. The cost is low, yet with the right paper and color pigment
gum prints are permanent like aquarell paintings.
Papar for gum printing is coated with a solution of gum arabic and ammoium dichromamate, and a watercolor pigment.
It is dried and multiple times contact-printed for at least four colors; red, green, blue and black. The paper is developed by floating
face down in water. The gum gradually dissolovs off the face of the print from those areas that did not recieve exposure, carring the pigment with it.
The paper has to be dryed for each color and typically one color per day can be fixed to the surface. A single print can take a week to
get ready.
