Lay Marks

Lay marks indicate the correct orientation and positioning of each press sheet: ensuring consistent alignment throughout the print run. They include front lay (gripper-edge guides), side lay (lateral positioning guides), and orientation indicators (showing which way is "up" and which side is "front"). Essential for maintaining registration between colors and between front and back on duplex jobs.

How It Works

Lay marks indicate the correct orientation and positioning of each press sheet: ensuring consistent alignment throughout the print run. They include front lay (gripper-edge guides), side lay (lateral positioning guides), and orientation indicators (showing which way is "up" and which side is "front"). Essential for maintaining registration between colors and between front and back on duplex jobs.

Front lay:Gripper-edge alignment marks. Position 8–12mm from the leading edge, outside the gripper zone. The press operator uses these to confirm correct sheet feeding direction.
Side lay:Lateral positioning marks along one side edge. Must match your press's guide side (operator or drive side). Ensures consistent left-to-right registration on every impression.
Orientation marks:Arrows or symbols indicating correct sheet orientation. Critical for preventing upside-down or reversed sheet loading: especially important on high-speed presses where errors compound quickly across thousands of impressions.

Options Guide
Mark Type

Choose the type of lay mark: front lay, side lay, center mark, or orientation indicator.

Front lay: marks at the gripper edge showing the correct feeding direction: the press operator aligns sheets against front lay stops. Side lay: marks along one side edge for lateral alignment: sheets are jogged against the side guide. Center mark: a crosshair at sheet center for front-to-back registration verification. Orientation: arrows or symbols indicating "this side up" and "front face": prevents sheets from being loaded upside-down or backwards.

Placement

Position lay marks along the appropriate sheet edges.

Front lay marks go on the gripper edge (leading edge). Side lay marks go on the guide side (operator side or drive side depending on press configuration). Center marks are placed at the exact center of both edges for duplex registration. Position all marks outside the trim boundary in the waste area so they don't appear in the finished product.

Size

Set the physical dimensions of each lay mark.

Marks should be visible during high-speed press operation: typically 5–10mm for main alignment marks, 3–5mm for secondary indicators. Line weight: 0.5–1pt for clear visibility. Marks that are too small are useless to press operators working at production speed; marks that are too large waste paper and may interfere with finishing.

Appearance

Configure mark color, line weight, and style.

Standard: process black (K-only) at 100%. Registration color (all plates) is used for duplex-alignment center marks so they appear identically on both front and back. Use a distinct style (solid, dashed, or double-line) to differentiate front lay marks from side lay marks at a glance.

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
Lay Marks Applied

Lay marks indicate the gripper edge (the edge that feeds into the press first) and the guide edge (the side that rides against the press side guides). These marks keep sheet orientation consistent through the press, which is critical for front-to-back registration on sheet-fed offset.

Expert Tip

Lay marks (side and front lays) tell the operator which edge feeds first and which side rides the guide. Place them at the gripper and guide edges matching your press configuration.

Lay marks placed outside the physical sheet area will not print. Make sure they fall within the actual press sheet dimensions.
