Perfect Binding Services
Perfect binding is one of the most popular binding methods used today for catalogs, softcover/paperback books and magazines. There is a large range of layout flexibility and the process produces printed materials that will be attractive and durable.
Perfect binding involves scoring the hinges of the cover, binding the cover to the leaves or unbound sheets of paper, then utilizing the 3-knife trim, which involves trimming down the book so that it is clean on all edges. The 3-knife trim is named as such because of the three cuts that are made: the top, bottom and face cut.
At Steve’s Bindery Service, Inc., we provide perfect binding to a wide range of products, including, but not limited to:
- Annual Reports
- Self-published works
Our Perfect Binding Equipment with PUR Glue
At Steve’s Bindery Service, Inc., our perfect binding equipment is the Muller Martini Pantera with PUR gluing. Polyurethane Reactive (PUR) adhesive is the overwhelming choice in the binding industry. When first introduced, PUR required a long set-up time – sometimes over 24 hours. Today, however, PUR gluing attains 80 percent of its green strength in only a few hours.
PUR glue utilizes a chemical reaction to bond to the book, drawing moisture out of the air. Because it is technically a moisture-curing product, the method used to apply PUR glue is critical. The computer-controlled system precisely applies the correct thickness of PUR glue, which also virtually eliminates any clean up or waste.
PUR glue is more flexible than the long-standing, traditional method of using Ethylene Vinyl Acetate or EVA glue. Once set, it is nearly impossible to tear out a page of a book bound with PUR glue. We can produce a perfect bound book as thin as 1/16 inch, which is simply not possible with EVA adhesives.
Each job is inspected for pagination, bleeds, crossovers and more to ensure the highest quality for our customers. Should a potential problem be identified, we contact the customer immediately and give him or her an opportunity to make changes. Then we proceed with the first finalized copy and ensure it is correct before continuing with the full run.
