Margins at the fold
Keep text and important elements away from fold lines (at least 4 to 5 mm). A fold running through text makes it hard to read, and artwork sitting across a fold can shift slightly.
Fold types
Half fold, roll fold, concertina (zig-zag) fold, gate fold: each one has its own panel logic, and panels that fold inwards are usually slightly narrower. Use the template for your chosen fold to size each panel correctly.
Marking up the finishing
Place fold and perforation lines on a dedicated guide layer, or describe them clearly — never print them in the final artwork. Don’t draw the perforation dots yourself in the print file.
Check before you send
- Content kept 4–5 mm away from folds
- Panels sized to the fold template
- Folds/perforations marked outside the printed artwork
Do I need to draw the fold lines?
