The Photographer's Formulary Kallitype Printing Kit provides an introduction the Kallitype photographic process.
Kallitype printing is similar to the Platinum/Palladium process in theory and technique. However, Kallitype printing uses a less expensive silver salt.
Although the outstanding permanence of Platinum and Palladium is not duplicated, good Kallitype prints have a Platinum-like quality.
Print color can be controlled by development. The prints may be toned with printing-out-paper toners, or Gold Protective (GP-1) toner.
With proper fixing and clearing, Kallitype prints have good permanence.
About 30 - 4 x 5" prints can be made using this kit.
