Tri-Fold brochures are created by folding a sheet of paper into three (3) equal sections, with one side folding over the other side (meaning overlapping the other).
This option provides you with six (6) spaces for content -three on the front and three on the back.
This style of brochure gives you an opportunity to present separate details about each of your products/services, or any of the various items that your company offers in single areas.
An excellent way to display individual facts separately, while the main overall subject of the brochure is still being presented. (like bullet points on a page, each section of the brochure represents one area of interest you are trying to convey).
