Guidelines for positioning the offset perforating rules should be clearly placed on the plates. Before beginning, make sure you can position the rule in precise accordance with the artwork. Be certain you also have the appropriate type and size of rule to complete the job correctly.
Paper is sticking to teeth on the perf
Possible Solution - Grippers need to be adjusted or replaced. Lay a piece of clear tape over the perf. Possibly apply a silicone spray to the rule teeth.
Perf is not perforating as desired
Possible Solution - Add pressure or change rule to a special high product.
Perf is slitting instead of perforating the paper
Possible Solution - Reduce pressure, try changing to a special low product, or overlay the rule with a piece of clear film tape.
Rule is not perforating at all
Possible Solution - Use a good hard 3- to 4-ply non-compressible blanket. Check the pressure.Reverse or use back side of blanket if possible. Does this particular press have springloaded cylinders designed to release under pressure as a safety precaution?
Teeth are bending or breaking off
Possible Solution - Reduce pressure and make sure the correct height of perf for the stock is being used.
Perforation is straying from guidelines
Possible Solution - Reduce pressure. Try using a 1/2” to 3/4” masking tape to overlay the perf (especially in high-speed web operations that generate heat).
Indentation or shoulder mark in paper is appearing adjacent to the perforated line
Possible Solution - Back off the pressure. Try a center-mounted rule to distribute pressure evenly to both sides of rule.
None of the above

"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."

"I just wanted to thank you for demonstrating the Calcium Slayer and Flush. I have to admit we were skeptical about trying your product. We have tried other products and nothing can compare to what you brought. I didn’t realize that we had that much Build up on our rollers!!
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."

"Publication Printers has used H.S. Boyd’s Micro-perf product for 22 years. This product gives us the ability to create horizontal perfs, which allows us to offer more variety in our solutions for publishers. We use the product several times per week and are pleased with the ease of use. Running a printing company is the 21st century is largely dependent upon relationships with vendors who offer strong customer service and dependable products that will help us produce quality printed material. H.S. Boyd fits this criteria very well. We are happy to recommend them."
