ABSTRACT:
An improved diffusion-transfer processor for photomechanical reproduction of artwork and like mediums of the type using negative and receiver materials, wherein the materials are passed through a chemical solution discharged through a bath assembly. The processor includes a separator positioned forwardly of and intermediately between two sets of transport rollers which are located one above the other. One sheet of material is placed above the separator and the other sheet of material is placed below the separator, both sheets being received in the respective transport rollers simultaneously with their emulsion surfaces facing each other. The upper sheet is fed over a liquid-dispenser bar, and the lower sheet is fed under the liquid-dispenser bar to allow the emulsion surface of the upper sheet to be bathed in the chemical solution. The two sheets of materials are brought together rearwardly of the bath assembly by means of a set of press rollers positioned to simultaneously accept both negative and receiver materials, whereby their emulsion surfaces are brought into direct contact for image transfer.
