ABSTRACT

Salted paper is sensitive to actinic light, the portion of the light spectrum that causes photographic chemical reactions. The simplest method to determine exposure is to take a strip of Pictorico Ultra ohp and expose a sensitized strip of salted paper under it, revealing more and more of the paper to the sun or uvbl in 5-minute increments up to 1 hour. Many salt printers use plain water washes and do not add salt to the first water wash after exposure, and with some water supplies this is ox because the water contains chlorine. Processing salted paper is a simple procession through a number of trays of salted and/or plain water, toner, fixer, hypoclear and plain water again, much like printing in the b& w darkroom, except for one big difference: toning occurs before fixing instead of after in the salted paper process because toners produce light-sensitive chlorides.
