 The TPI of a perforating rule determines how easily the final product will tear. The behavior changes between standard and micro-perforations.

With standard perf, a higher TPI count results in a stronger, harder-to-tear perforation.

• 12-16 TPI: Hard to tear. Often needs to be folded first. Ideal for mailers or documents that require durability.
• 8 TPI: Medium tear. A good general-purpose option. 
• 6 TPI & Lower: Easy to tear. Stocks above 8 pt. will separate with very little effort. Ideal for tickets and coupons.

With micro-perf, the rule is reversed: a higher TPI count creates a finer, easier-to-tear perforation that leaves a cleaner edge.
