I like the look of the perforation you get from a Rosbach perforator (holes like with postage stamps) more than from a normal linear perforation.

Can you do this with a Windmill or a C&P?

In a word—no. Imagine what a mess all those chads would make inside of a Windmill-ugh. You might be abIe to acheive the result and more (curved perfs) on a Bobst style die-cutter, but I’m not sure how that would work out. Chad removal seems to be the biggest technical problem.

this looks like it would be a hot mess in either press…

But I do prefer the outcome over the other style of perforation. I’m interested to see the replies.

I believe I’ve seen this effect done before (maybe I saw a tutorial?)… I want to say beastpeices?

I bet you could fashion a catch at the bottom of the platen if you were really concerned about the chad. My press came with a nice patina of old, greasy paper at the base.

If you were to have such a thing it would have to lock into the chase and each “pin” would have to be hollow (punching against a die-cutting jacket), with a way for the “holes” to come out the back-behind the chase. Honestly I think it would be simpler to find a perforator, especially one of the really neat rotaries that Rosback built late in the game if production speed is an issue.

Mating pins/holes would be very difficult to arrange on a platen since getting the two portions to register would be a bear. Still, perhaps somebody has engineered something.

I’ve had my die maker use different types of hole punches. One has a small spring inside that “ejects” the chad. The other kind has a hole in the side of the shaft that allows the chad to come out the side of the hole punch. I haven’t run across one that ejects behind the chase. The type used varies by hole diameter.
