The United States Air Force presently uses SO-233 Duplicating Film for the processing of transparent prints and has achieved a long straight line curve for reproduction control purposes. Type 8430 Duplicating Film is also used for the same purpose but for different contrasts. Their problem was that the developer and Type 8430 were not compatible and did not have a sufficiently high density or a long enough straight line. The results of this experiment have yielded a monobath formulation which when used with type 8430 film will give the desired density and straight line required.
