Registration Punch Update

Today I completed a registration punch setup to include permanently mounted hole punches. Can’t wait to try it out on multi-layer carbon transfer printing. Not fancy, but I believe it will work.

Completed punch ready for action
I mounted two paper punches from Staples, then I added aluminum bar stock and a handle on top which is actually a drawer “pull.” Pressing on the handle activates both sets of punches.
Rear view of the hole punches. I staggered them asymmetrically to prevent ever placing a negative upside-down.
Here is an idea of the hole pattern. I centered the orange masking film just to get all six holes in the shot. Normally, this 20″ sheet would be placed against the aluminum stop seen on the left and because of its size would have received only five punched holes.
