z-fold

Explanation:

It is the Z fold brochure, which has multiple panels, and which keeps folding in. It is also termed as the fan fold brochures and is made by zig-zag folding a varied size of sheets of paper two times in the shape of the z letter. It looks like a fan as the panel does not fold inside one another. It allows the printing of large flow charts, maps, graphs, or any design that is image centered. And since all of the folding sides are of equal lengths, you can find much good use of the area to create quite an awesome eye-soothing designs.
