Negatives are easily positioned in slots on the mask of the Proof Printer and the resulting contact sheet enables easy choice of which negatives to enlarge. An entire 120 film can be proofed on a single 8 x 10in (20.3 x 25.4cm) sheet of paper.

The 6 x 6cm model takes four strips and is suitable for 6 x 6cm, 6 x 4.5cm, and 6 x 7cm formats.
