accordion fold

The accordion folds (sometimes referred to as z-folds) are some of the most common folding styles used in brochure folding. The key characteristic of accordion folds is the “zigzag” back-and-forth nature of the panels.

Accordions are an excellent choice for a variety of applications but are notoriously problematic during auto-insertion into envelopes. This style of folding offers flexibility, with the potential to add as many panels as the limitations of press and folding equipment can bear.
