PATERSON PROOFERS

Proofers for every format, although the most popular is the 'Pro-Proofer', the most popular as it can be used for all formats.
The 35mm and 120 formats use an integrated mask which holds the edge of the film strips, making it easier to make multiple copies.
On the other hand, you could use Scotch Magic tape run along the short edge of the strips, tacking them down onto the Pro-Proofer, to achieve the same result (old pro printers method).
