Folding

There are many different ways to fold paper. In the world of printing, we have a number of standard folds, some of which are demonstrated below.

Where possible, paper should be folded parallel to the grain of the stock. If folded across the grain, cracking can occur. Paper can also crack when it (or the coating on thepaper) is stretched beyond its tolerance.

To prevent or reduce cracking on heavier stocks, paper can be mechanically creased before it is folded.
