Advanced (GS1, checks, profiles, retail add-ons, supply-chain carrier)
Style (readable text, bar height, export size)
Bar height stretches bars vertically, which scanners ignore (only horizontal timing matters). The SVG download keeps the engine's exact geometry.
Specification
| Standards | ISO/IEC 15417, GS1 General Specifications |
|---|---|
| Character set | Use GS1 application-identifier syntax. The print profile is rendered by BWIPP. |
| Lengths | (01)09501101530003(10)LOT123 |
| Check digits | Mod-103 plus GS1 AI data rules enforced by the engine. |
| Quiet zone | 10X quiet zone on each side. |
| Capacity | GS1 element strings such as (01)…(10)…. |
Usage
GS1-128 profile identifies cartons and containers moving through warehouses: print it large on cases where logistics scanners expect GS1 data.
- GS1-128 profile on corrugated cartons for warehouse receiving
- GS1-128 profile on pallet labels alongside human-readable GTIN
- GS1-128 profile proofs exported as SVG for thermal printers
Shape
Pros
- GS1-128 profile carries GS1 identifiers that warehouse systems already understand.
- Carrier choice (ITF-14 vs GS1-128) is explicit where the standard allows it.
- Print SVG uses profile-correct geometry for cartons and pallets.
- Every symbol is decoded again locally before it is shown.
Cons
- GS1-128 profile needs large, high-contrast prints — small inkjet labels fail.
- Corrugated texture and shadows lower first-pass reads.
- Wrong carrier selection confuses receiving systems.
- Screenshots are proofs, not print-quality certification.
Form requirements
- Enter (01)09501101530003(10)LOT123.
- Use GS1 application-identifier syntax. The print profile is rendered by BWIPP.
- The symbol is decoded again locally before preview and downloads unlock.
