Carton Print Inspection Challenge-test checklist

What evidence should be agreed before acceptance testing for carton print inspection?

In brief

For Carton Print Inspection, define the operating conditions for false-accept, false-reject and challenge criteria: the normal state, credible extremes, how the relevant values or conditions are measured, and which decision or outcome they affect.

For in-line inspection using carton artwork and variable-print checks, describe the realistic range and how changes in false-accept, false-reject and challenge criteria affect the result you need.

On the production floor

Turn your production information into clearer decisions — Carton Print Inspection

Plan carton print inspection around representative good, bad and marginal samples, line presentation, lighting, reject handling and challenge criteria. Discuss an optical feasibility trial with Oxford Vision Systems. Use this guide to resolve false-accept, false-reject and challenge criteria before it limits the final system.

What to record

False-Accept, False-Reject and Challenge Criteria: condition, range and effect on your process

Current condition

Describe how you observe or measure false-accept, false-reject and challenge criteria in your operation, including sample condition and any measuring limits. For a project focused on carton artwork and variable-print checks, also record the production state in which each observation was made.

Realistic range

For Carton Print Inspection, include normal production conditions, credible extremes, product or part variants and changes over time.

Effect on the system

Show which settings, safeguards, maintenance tasks, decisions or required outcomes are affected by changes in false-accept, false-reject and challenge criteria.

Before you contact us

Five questions about false-accept, false-reject and challenge criteria for your application

  1. Who can confirm this information?Identify the person responsible for false-accept, false-reject and challenge criteria in production, quality, engineering or operations.
  2. How representative is the sample?Include age, supplier, batch, environment and upstream process state where they affect carton print inspection.
  3. What is the difficult condition?Include the slow, reflective, flexible, dirty, damaged, marginal or uncommon case that your system must still handle.
  4. How will you judge the result?Agree the method, repetitions, acceptable range, result record and the response if the observed result falls outside the agreed range.
  5. What else must be coordinated?Your final carton print inspection scope must also account for recipe, reject and line-control interfaces, false-accept, false-reject and challenge criteria, current regulations and the conditions at your site.

Question 1

Visible Defect or Measurement Definition for Carton Artwork & Variable-Print Checks

For Carton Print Inspection Challenge-test checklist, describe the current position, required outcome, acceptable limits and known exceptions for visible defect or measurement definition for carton artwork & variable-print checks. That lets us compare options against your real production rather than one nominal value.

Question 2

Good, Bad and Marginal Sample Range

For Carton Print Inspection Challenge-test checklist, describe the current position, required outcome, acceptable limits and known exceptions for good, bad and marginal sample range. That lets us compare options against your real production rather than one nominal value.

Question 3

Part Presentation and Production Speed

For Carton Print Inspection Challenge-test checklist, describe the current position, required outcome, acceptable limits and known exceptions for part presentation and production speed. That lets us compare options against your real production rather than one nominal value.

Question 4

Optics, Lighting and Environmental Conditions

For Carton Print Inspection Challenge-test checklist, describe the current position, required outcome, acceptable limits and known exceptions for optics, lighting and environmental conditions. That lets us compare options against your real production rather than one nominal value.

Question 5

Recipe, Reject and Line-Control Interfaces

For Carton Print Inspection Challenge-test checklist, describe the current position, required outcome, acceptable limits and known exceptions for recipe, reject and line-control interfaces. That lets us compare options against your real production rather than one nominal value.
