Four models are available in this range of Contact Proof Printers:
- PTP619: Designed to proof a complete roll of 35mm (36 Exposure) film on standard 8” x 10” (20.3 x 25.4cm) photographic darkroom paper.
- PTP620: Designed to proof a complete roll of 120 film on standard 8” x 10” (20.3 x 25.4) photographic darkroom paper.
- PTP621: Designed to proof up to seven strips of six 35mm negatives onto a 24 x 30cm sheet of photographic darkroom paper.
- PTP623: Is designed to contact print large negatives up to 10” x 12” (25.4 x 30.5cm)
It can also be used to hold prints or other artwork flat for copying purposes. In use the glass plate is hinged upwards and the negatives are positioned into the slots on the edges of the black mask fixed onto the under surface of the glass. The edge numbering on the film is visible through the mask allowing them to be printed onto the sheet of printing paper. A sheet of photographic printing paper is inserted emulsion side up into the contact printer. The foam pad ensures that the printing paper is in total contact with the negatives once the glass plate is clipped shut.
