Digital BW, The Print

Guillotine trimmers have a basic problem that makes it difficult to use them
for precise cuts. They tend to draw the paper toward the blade as the cut is
made. This "draw" is hard to overcome unless you have a means to hold the
paper VERY firmly. It's further complicated by cutting multiple pages such
that the page on the bottom will be cut shorter than the page on top.

Printers and binders use a different type of guillotine cutter that slices
through the paper in the direction of the blade as it plunges down, sort of
a one-direction sawing motion. Even with these very precise, very  expensive
cutters, an experienced operator will expect some "draw" and may have to
dial in some compensation.

Go rotary. I made the mistake of buying a cheap one on Ebay and the blades
are terrible. It's a clone though and maybe the Rotatrim blades will fit it.
I'll have to check.
