Web width vs print width: will your label layout fit?

Three dimensions to keep separate

Maximum web width describes the width of material a press can accept. Maximum print width describes the usable image width across that web. Print repeat describes the distance along the direction of travel for one repeating layout. These values answer different questions.

Do not choose a machine from its model number alone. A wider material path does not automatically mean the entire web can be printed, and a cross-web dimension does not tell you the permitted repeat length.

A concrete HCF350 example

The HCF350 documents checked for our product guide specify a maximum material width of 350 mm (13.78 in) and a maximum intermittent print area of 340 mm across the web by 370 mm along the repeat (13.39 × 14.57 in). A 350 mm-wide image therefore does not fit inside the documented 340 mm print width.

Use these dimensions for the HCF350 only. Confirm the current HCF450 configuration separately, and do not substitute figures from HCHF450 or the HCL350-6C letterpress.

Check labels across the web, including the gaps

As a layout illustration, four images each 80 mm wide with three 4 mm gaps need 332 mm across the print area: 4 × 80 + 3 × 4 = 332 mm. Four 85 mm images with the same gaps need 352 mm and exceed a 340 mm print width.

This is an image-width calculation, not approval of a finished die layout. Separately allow for material-edge margins, the cutting arrangement, waste stripping, print bleed and any register marks. Confirm whether marks are included inside the quoted printable area.

Then check the repeat and finishing tools

Send both the cross-web layout and the machine-direction repeat. Include the gap between successive labels and any artwork or marks beyond the finished label edge. A layout that fits across the web can still exceed the machine’s supported repeat.

Die cutting, foil and lamination may impose additional tooling or process constraints. Full-rotary and intermittent operation also have different relationships between repeat and tooling. Ask the equipment supplier to confirm the complete job, rather than checking printing alone.

What to send for a useful check

Keep a copy of the agreed layout with the quotation. It makes comparisons between machine configurations much more precise.

• A dimensioned artwork or layout with the feed direction clearly marked.
• Finished label width and length, labels across, gaps and register marks.
• Material roll width, face stock, liner and total thickness.
• Required printing mode, colors, die cutting and other inline processes.
