How It Works

Folding marks are short dashed or solid lines printed at the sheet edge, indicating fold positions for bindery and finishing equipment. Essential for brochures, mailers, greeting cards, packaging, and any multi-panel product. Supports standard fold patterns (half, tri-fold, Z-fold, gate fold, accordion) and custom fold positions for non-standard layouts.

Fold type:Half fold: 2 panels (cards, invitations). Tri-fold: 3 panels (brochures, menus). Z-fold: 3 panels alternating (mailers). Gate fold: 4 panels meeting at center (presentations). Choose Custom for non-standard panel sizes.
Custom positions:Enter fold distances from the left edge, separated by commas. All values in your selected unit. Ensure fold positions account for paper thickness: inner panels on thick stock should be 1–2mm narrower to fold flat.
Line style:Dashed lines (industry standard) distinguish fold marks from crop marks. Solid lines are more visible but may be confused with trim marks. Use a different color (cyan or light gray) for additional differentiation.

Options Guide
Fold Type

Choose a standard fold pattern or enter custom fold positions.

Half fold: one fold at center (2 panels). Tri-fold (letter fold): two folds creating 3 panels: inside panel is slightly narrower to nest cleanly. Z-fold (accordion): two parallel folds with panels alternating direction. Gate fold: two folds bringing outer edges to center. Roll fold: panels fold inward sequentially. Custom: enter exact fold positions in your preferred unit for non-standard layouts.

Fold Positions

Enter custom fold positions as distances from the left or top edge.

Each position represents a fold line measured from the leading edge of the sheet. Enter multiple positions separated by commas. Values are in your selected unit (inches/mm/points). Example: for a custom tri-fold on Letter paper, enter "3.667, 7.333" (in inches) for equal panels.

Line Style

Configure the appearance of fold mark lines: style, weight, length, and color.

Solid lines are most visible; dashed lines (standard in commercial print) distinguish fold marks from crop marks at a glance. Line weight: 0.25–0.5pt is typical: thin enough to be unobtrusive but visible to finishing operators. Line length: how far the mark extends from the sheet edge into the margin area. Color: typically light gray or cyan to differentiate from trim marks.

Position

Which edges of the page receive fold marks: top, bottom, or both.

Both edges is standard: marks at top and bottom of the sheet let the finishing operator align the fold from either direction. Top-only or bottom-only can be used when one edge has artwork extending to the sheet edge.

Pages

Specify which pages to process using a range expression.

Examples: 'all' = every page. '1-5' = pages 1 through 5. '1,3,5' = specific pages. '1-10 odd' = odd pages 1-9. '2-20 even' = even pages 2-20. 'last' = last page. 'last-2' = third from last. Ranges are 1-based. Combine with commas: '1-5, 8, 12-15'.

Configurations & Variations
Fold Marks Applied

Fold marks appear as dashed or solid lines at each fold position, extending slightly past the trim edge. The bindery operator uses these to set up the buckle or knife folder. Mark length and thickness are configurable; use heavier marks for thicker stocks that are harder to fold precisely.

Expert Tip

Place fold marks at every fold position. For a tri-fold brochure, remember the inside panel is typically 1-2 mm shorter than the outer panels, so adjust your fold mark positions to match.

Fold marks that extend into the live area will be visible on the finished piece. Keep them strictly in the bleed or trim zone.
