<p>Proofing machine in which the means for exposing the proof paper comprises a light carriage adapted to be moved by the operator to an open position for loading proof paper and negatives and a closed position where the exposure is initiated and thereafter automatically terminated at the end of the exposure cycle and there is provided means for exposing a plurality of proofs of the same size simultaneously as well as to accommodate proofs of different size comprising a plurality of separate and selectively usable vacuum systems and systems of locator pins.</p> |
