Formulary's 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 - 4x5 inch prints can be made using this kit.
