Carbon Transfer Printing
Instructor: Sandy King
Carbon transfer is a contact printing process invented in the mid-19thcentury. Paper or a synthetic support is first coated with a layer of carbon or other pigment suspended in gelatin, and when dry this becomes known as the carbon tissue. To make a print the carbon tissue is sensitized with dichromate and then exposed under a negative to a light source right in UV radiation, hardening the gelatin in proportion to negative densities. The carbon tissue is then transferred to a final support, and then developed in warm water.
Carbon prints have unique surface and textural qualities that can include surface relief and can be made in virtually any color or tone desired. Carbon prints are made with pigments that have excellent light fastness and in most cases their stability and permanence are limited only by the final support on which they are placed.
The carbon transfer workshop at f/295 will provide detailed hands-on instruction that will demonstrate the workflow of complicated but fascinating process. The skills you will acquire include making carbon tissue,preparing papers to use as final support for carbon printing, sensitizing carbon tissue, exposing the tissue to a negative, and developing the print.
Participants should bring their own large format negatives (sizes from 4×5″ to 5X7″ are acceptable), or digital files for printing digital negatives on site.
Class is limited to 10 participants
