Carbro-Chromatone
Description
“References to Carbro-Chromatone prints are sometimes found in the literature on early color photography. These prints were made using a combination of the two processes they were named after. The method was described by Harlan L. Baumbach in the September 1937 issue of the magazine Camera (Baumbach 1937). Separation negatives were printed on Chromatone stripping papers,29 which were placed in contact with carbro pigment papers, from which they became colored. The three Chromatone images were assembled as usual. Overall, the operations were much simpler, but two sets of rather expensive papers needed to be used—trichrome carbro pigment paper and Chromatone stripping paper—and the process never became popular (Henney 1938: 266).”
