Labels and codingWhat information is needed to specify equipment for barcodes?
Practical guidance for barcodes: capture samples, dimensions, output, acceptance tests and site constraints before buying.
Read the answer →What normally controls the result?
Reliable identification needs a controlled pack surface, correct label or ink, stable web or print path, accurate triggering and verified finished data.
- Pack surface and presentation
- Label, liner, adhesive or ink
- Sensor and trigger position
- Web tension or print-head distance
- Wipe-down, rotation and code verification
Information that makes a recommendation more accurate
- Pack samples
- Label reel or print substrate
- Label size, gap and reel direction
- Required code or artwork
- Position tolerance
- Line speed and data interface
