ITF-14 for corrugated case marking
Case and carton marking on corrugated packaging relies on ITF-14, which bwip-js draws with a bounding-box border by default to help it survive rough print and handling conditions.
Preconfigured for corrugated cases
This experience doubles the bounding-box border width to 8 ("borderwidth": 8) from bwip-js's default of 4, for a more visible frame on corrugated cases.
Example data
The generator is seeded with a 13-digit GTIN-14 fragment that bwip-js completes with a computed check digit; replace it with your own case's GTIN.
Workflow
Enter your 13 or 14-digit GTIN-14, confirm the bearer bar in the preview, then export SVG for case artwork.
Job-specific settings
Keep the bearer bar (bwip-js's bounding-box border) enabled for corrugated print processes: GS1 General Specifications describe it as mandatory where feasible, since it equalizes flexographic printing-plate pressure across the symbol and helps stop the bars from spreading on corrugated stock.
Scanning notes
The bearer bar surrounds the whole symbol, including its quiet zones, and reduces misreads from a skewed scan beam entering or exiting through the top or bottom edge; it does not shrink or replace the quiet zone bwip-js already reserves.
Common mistakes
Disabling the bearer bar to save space works against GS1's printing guidance for corrugated cases and is a common source of print-quality and partial-read complaints.
Standard
GTIN-14/ITF-14 case marking follows GS1 General Specifications.

If the case also needs lot/date/SSCC data, use the GS1-128 generator instead.
FAQ
Why is the border thicker here than on the primary generator?
borderwidth: 8 doubles bwip-js's own default of 4, for a more visible bearer-bar frame on corrugated stock where the base material is coarser than a typical retail label.
