A common question at Bargain Printing is, “What type of fold should I choose?”
Here is a rundown on the common types of folds:
Bi Fold – Commonly referred to as a short or long fold. It is just one fold made to the paper in either direction.
A short fold, would be a fold across the shortest dimension of the paper. For example, a short folded 8.5″ x 11″ sheet would fold down once to 8.5″ x 5.5″
A long fold, would be a fold across the longest dimension of the paper. For example, a long folded 8.5″ x 11″ sheet would fold to 11″ x 4.25″
Tri-Fold – A fold where a three panel piece has both side sections folded inward, one on top of the other Each section is approximately 1/3 the length of the piece. Also known as a C-fold or letter-fold.
Z-Fold – A paper fold represented by back and forth folds into three panels.
That pretty much covers the typical fold types when printing a brochure. Another good term to know is scoring. Scoring is a crease applied, in a straight line, to a sheet of paper to allow it to fold easier and more accurately.
