I don't know if you might have one or not, but we use a large Ingento
36x36" paper cutter that to cut pre-exposed plate material and plates.
The part that falls down to the tray needs to be brought back up the
cutter, turned around, and the slight curl at the cut edge needs to be
trimmed off. We've been using our paper cutter for years at the advice
of another letterpress printer and it hasn't needed any special
maintenance as a result. Some students have had trouble getting the
hang of it at first, but the tricks are:
1) Keep the plate at the very top, where the blade meets the cutter,
for best leverage. The cut takes much less force.
2) Always cut with the plate surface up, and the metal side down.
3) Hold the plate firmly and cut firmly. Often when a student has
trouble cutting, it's because they were skittish or ginger about
making the cut in the first place. Usually this happens with students
who haven't had a lot of experience with tools. It doesn't really take
any special degree of force. I'm a pretty slight person and I do it
all the time.

Could use some advice on metal magnetic backed photopolymer plate
cutting. Is there some alternate method of cutting this material,
other than investing $1500.00 in a metal shear? I am a Letterpress
shop that has recently begun photopolymer printing.

hinged to it. At 24", it is just enough leverage to cut through
unexposed .060" photopolymer. Kim's advise is good, especially the
back-trimming. I'd add that wiping the blade with a damp rag before
each cut helps the blade slide through unexposed photopolymer, and
removes any residue. A gummy blade may lead to grabbing and bending
over the plate.
The more expensive Kutrimmer does have a heavier blade, safety guards
on handle and at cutting edge, clamp, side guide: all real improvements.
