Question: The cover of the brochure that my printer delivered has cracking on the spine, why did this happen?

Answer: Scoring is a part of the bindery process that will help prevent or reduce cracking when folding stock.

The specific stock you are using will determine the most effective scoring method. There are three ways to score your material.

A press score is achieved by placing a score rule (a thin piece of metal with an adhesive backing) directly on the impression cylinder of a press. It will leave an indented impression on the press sheet, creating a channel for folding. This is the most economical to achieve a score line, but does not always yield the best results.

A rotary score uses a wheel placed on the bindery equipment prior to folding as an in-line process. This will create an adequate score line, especially when folding with the grain of the paper.

A die score involves a separate production process in which a steel scoring rule is placed in a jig or imbedded in a piece of wood, clamped on a die cutting press and produced as an off-line process. The die score is usually used on a piece that has multiple score directions, such as a pocket folder. This process creates a much better score that stretches the paper fibers. The die score is the best method for reducing cracking…it is also the most costly process.
