PLEASE NOTE: An non-acidic fixer solution such as TF-4 OR TF-5is recommended for achieving maximum pyro stain on the negative. A conventional rapid fix may diminish staining effects of pyro and PMK formula.
The PMK formula was developed by Gordon Hutchings, and is designed as a universal developer for a wide variety of modern emulsions used under diverse conditions. PMK stands for Formulary'sPyro-Metol-KodalkFormulary's. Kodak has changed the name Kodalk to Balanced Alkali - this is their proprietary name for sodium metaborate. The formula is constituted to achieve the best overall results in consideration of the following technical criteria: sharpness, maximum image stain, minimum general stain, edge effects, film speed, flexibility for Zone System Plus and Minus development, stability, repeatability, convenience of use and long shelf-life. The PMK formula consists of two stock solutions. The 'A' stock is the developer agents and the 'B' stock is the alkali, or accelerator. Our stock solution dilutes to make 25 or 50 liters of working solution.
