What is Grain Direction?

Grain Direction refers to the orientation of fibers in a piece of paper, affecting how it folds and prints.

When fibers are aligned parallel to the length of the sheet (long grain), the paper is more flexible along its width and tends to fold more easily and neatly in this direction. Conversely, short grain paper has fibers aligned parallel to its shorter dimension, offering better stability and less curling when processed through printers or copiers. Understanding grain direction is crucial for achieving optimal results in both print quality and durability, especially for projects involving folding or binding. Professional printers carefully consider this factor to enhance the presentation and longevity of printed materials.
