SHEET / Plan
Grain Direction
Choose a grain that keeps folds clean and pages standing.
What it does
- Paper folds along the grain and cracks across it.
- Grain direction is fixed when the sheet is ordered, not at the folder.
- Every folded job should state grain on the purchase order.
How to use it
- A sheet cut to fit a press may arrive with the grain across the short side; test before ordering.
- Scoring helps across the grain but does not make it equal to folding with the grain.
- Write the grain axis on the layout, not only in the email thread.
- For a landscape book, the grain rule follows the spine, not the page orientation.
Safety notes
- A cover folded across the grain will bow after binding even if it looks right on press.
- Never accept a paper substitution without rechecking grain and caliper.
