A Graphic Arts Glossary #7

This is the seventh post in a series. Watch this blog during the months to come for further installments in this ongoing series.

The purpose of the series is to define key terms used in the graphic arts industry.

The seventh term in the series is grain.

Grain: A paper’s grain is the direction in which most of the fibers line up during the manufacturing process.

crossgraindirGrain is determined during the paper making process, when plant fibers, typically wood pulp, tend to line up in one direction or the other. Paper is identified as either grain short (grain is parallel to the paper’s short side) or grain long (grain is parallel to the paper’s long side), depending on how the paper is cut. It is easier to fold, bend, or tear the paper along the same direction of the fibers. Printing is usually done so that if folding is required, the fold is done parallel to the grain.

The eighth term in the series will be halftone.
