Current condition
Record the bottle or label construction, supplier, colour, finish and sample batch. Mark the intended code area, including ribs, curves or label overlaps, and provide the longest required message and character size.

Trial the actual bottle wall, cap, coating or label for code contrast, placement and pack condition before choosing a bottle laser-coding method.
General industrial marking and labelling. Bottle laser coding must be assessed using the actual bottle material, required mark and production conditions.
Identify the exact surface that receives the code: bottle wall, cap, coating or applied label. Trial each intended material, colour and finish with the required message and mark location. Review readability and unwanted effects on the pack separately; a result on one surface does not approve another.
Compare representative supplier and production-batch samples using the same selection questions. Retain marked examples for the packaging owner to assess against appearance and functional requirements.
Plan bottle laser coding around your identifiers, substrates, production events, system interfaces, exceptions and verification records. Discuss a practical data-flow approach with Oxford Traceability. Use this guide to resolve substrate, label or tag behaviour before it limits the final system.

For Bottle Laser Coding, include normal production conditions, credible extremes, product or part variants and changes over time.
Keep separate observations for contrast, character formation, placement and unwanted effects on the bottle, coating or label. Record the tested surface and conditions; do not transfer approval from a convenient sample to the full pack range.
Provide the longest approved date or batch message, character size and any machine-readable content. Readability and correct encoded data remain separate acceptance checks.
Keep bottle wall, cap, coating and label trials separate. Compare the intended material and colour variants, and retain samples showing the acceptable boundaries of contrast and placement.
Assess the bottle support, spacing and orientation through the marking window. Include rotation, rocking, speed changes and the first bottle after a pause rather than judging a stationary sample alone.
Show where the code data originates, which event selects the job and which acknowledgement confirms that the approved message is active. Include the marking and inspection points in the bottle path.
Separate an absent code, unreadable code and readable but incorrect value. Agree whether each stops production or causes a reject or hold, and confirm the affected bottle reaches that decision.
Use the acceptance checklist to retain the sample identity, message, result and final disposition. Material response, protective measures and pack approval require the responsible project review.
