I have a chance to acquire a #2 in great condition, judging from the photos sent me. My shop has an SP-15, but it tends to be a bottleneck for members of our co-op…so we thought of getting another, proofing press, without an inking capability. Mainly for proofing, but hopefully for block printing and simpler projects. Now that I see what it looks like, I have two questions about it. It has no grippers…is there a way printers used it that allowed them to make multiple prints with accurate registration? The other question is about the two small platforms at either end that sit above the cylinder height. they seem too small for paper…what are they for?
