ABSTRACT
The term “carbon process” is generic and can potentially refer to a wide range of practices, including even contemporary inkjet/giclee printing, in which an image comprising carbon pigment is produced on some type of substrate, usually paper. This chapter provides a historical review of non-transfer methods of carbon printing, discusses the various light sensitizing compounds that have been in carbon printing in place of dichromate, with some practical workflow examples that utilize these non-standard methods or chemical compounds. In the first several decades of the twentieth century there were many attempts by amateur photographers to emulate the surface qualities of the commercial direct carbon papers using various combinations of colloids including albumen, casein, gelatin, gum, fish glue. Materials for a similar type of gelatin based indirect film system are still marketed as of 2018 by Ulano. To expose, place the emulsion side of a right-reading negative in contact with the base side of the pre-sensitized carbon tissue.
