Carbon Transfer Printing - Developing the Print
I am the only commercial Carbro Printer in the world. Before I share my experiences how to make the Carbro print, I would like you to enjoy a piece of an article by T. Baldwin written in It is very doubtful whether any process so completely like the requirements of the artistic photographer as does the carbon process. Its long scale, its deepest shadows combine to render it the most perfect of photographic printing methods. Carbon printing as we know it today is based on the fact that a mixture of gelatin with as chromic salt is gradually hardened and rendered insoluble on exposure to light or chemistry. If, therefore, paper is coated with such a mixture of sensitized gelatin, containing any permanent pigment — carbon was originally used — and if this paper is placed underneath a negative and exposed to actinic light, we shall have a positive image formed consisting of soluble and insoluble gelatin; insoluble in exact proportion as the light has reached the surface of the pigment compound.
A working guide to making carbon and carbro prints, including detailed instructions on making carbon tissue and final support papers.

A carbon print is a photographic print with an image consisting of pigmented gelatin , rather than of silver or other metallic particles suspended in a uniform layer of gelatin, as in typical black-and-white prints, or of chromogenic dyes, as in typical photographic color prints. In the original version of the printing process, carbon tissue a temporary support sheet coated with a layer of gelatin mixed with a pigment—originally carbon black , from which the name derives is bathed in a potassium dichromate sensitizing solution, dried, then exposed to strong ultraviolet light through a photographic negative , hardening the gelatin in proportion to the amount of light reaching it.,
