How to Perforate Blotter Paper (like LSD)? Answer:

From time to time I research a question and don't find an answer.  These make the best blog posts, today's question involves "How to make the perforations on blotter art?"

The answer it seems is being quietly hidden by those cashing in on the "blotter art" phenom, and after many Google searches and a few exasperated quits and restarts, I think I have stumbled upon enough clues to point the interested reader in the right direction.

The answer is they use a perforation board as seen above.  These are outfitted either on a manual perforation press, or otherwise fashioned to perforate the paper.  Individual steel perforation rules, or the cutting piece, can be purchased from suppliers either in precut lengths or by the coil.

And that is how the professional blotter art perforation is done today.  The same way it has been done for decades.  See below for a picture of an older perforation machine.

And here is a picture of the state-of-the-art model:
