Multiple factors affect the choice of the appropriate offset perforating rule for any job: type or brand of paper, type of press, experience of the press operator, and application techniques. However, these guidelines offer basic criteria for making job-to-job decisions.
- 12-16 TPI – “medium” to “very hard to tear.” Possibly need to fold before tearing. Ideal for mailings and other applications that require a lot of handling.
- 8 TPI – “medium” to “easy to tear.” Stocks above 8 pt. will almost fall apart after folding.
- 6 TPI and lower – “very easy to tear.” Stocks above 8 pt. will almost fall apart after folding.
- Normal perf (3–16 TPI) tear harder with a higher count of TPI
- Micro perf (30-50 TPI) tear easier with a higher count of TPI

"At Print and Pack we are the Komori agents for Australia and New Zealand and have large 40′ 8 and 10 colour perfectors running HUV inks. I tried the Calcium Slayer at two of our biggest users and the results were amazing. Never before have they being able to get so much debris out of the rollers without having to take them out and hand clean. The rubber and copper rollers have never looked so clean. I have both customers now asking when they can get their hands on more product."
Steve Harper, Pack & Print

Calcium Slayer and Flush is safe and easy to use. I’m sure we will be extending the life of our rollers by using this product and it will only make printing easier. I highly recommend this product for all print shops!
Please feel free to use our picture and testimony to advance this great product."

"The PPP system gives us the ability to keep die cutting work in house. We do not have to rely on a third party vendor. As a result, we are able to keep our costs competitive, control the quality as well as the turnaround time. By purchasing a PPP system, we can use equipment that is already in our shop."
