We perform Perforation and Micro-perforation. Perforation is used for sheets of paper or card stock, these perforations are 12 small holes per inch and are called the perforation marks. A great example of perforation is a postage stamp, which is perforated on every side. This process is made by piercing and boring the paper or card stock.
Micro perforation is card stock or a sheet of paper that has been perforated, perforation is when very small holes are punched into the paper or card stock. These perforations make it easier to separate by folding to tear the document along a dotted line. In micro peroration there are 30 small holes per inch with each perforation.
