Grain |
| |
Refers to the alignment of fibers in the direction of their flow on the paper machine. Long grain describes fibers running parallel to the longest side of a sheet. Short grain running parallel to the short side. Folding and scoring work best when done in the paper's grain direction. Grain also affects tear strength, stiffness, and dimensional stability. |
| |

Direction in which the fibers of machine-made paper lie due to the motion of the machine. When machine-made paper is moistened, the fibers swell more across their width than along their length, so the paper tends to expand at right angles. |
