Requirement
Define the visible holes, marks and defects to reject, acceptable variation and the smallest unacceptable examples. Agree the intended result, defect-position and affected-material record, keeping separate tests outside that conclusion.

Film Defect Inspection Specification Checklist
Specify visible film defects with sample decisions, full web width, clear or printed regions, representative tension and speed, optical trials and affected-material records.
Record the visible defect types and acceptance boundary, identified good, bad and marginal film, full width and representative tension and speed. Include clear, printed and reflective regions in the optical trial. Define the intended recipe/control response and how defect position and affected material will be recorded, with false-accept and false-reject criteria agreed.
Use the defect and sample definition and challenge-test evidence checklist. Separate confirmed requirements, sample limits and conditions still needing a representative optical trial.
On the production floor
Describe what the complete process needs to achieve — Film Defect Inspection
Plan film defect 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. A clear brief should state the operating range for visible defect or measurement definition for film holes, marks & visible defects and your requirements for false-accept, false-reject and challenge criteria.

For Film Defect Inspection, turn each checklist item into a range and a test
Range
Include identified good, bad and marginal film across the full required width, with clear, printed and reflective regions. State representative tension, speed and presentation conditions for the camera and lighting trial.
Check
Compare expected and recorded decisions over agreed repetitions and running conditions. Retain false accepts, false rejects, unresolved cases, optical setup and the observed recipe/control handover with each record.
For film defect inspection, use “shall” only for a requirement that can be demonstrated. Keep preferences, assumptions, provisional line connections and future options clearly separate.
Connected responsibilities
Be clear about what sits around your film defect inspection
Your final film defect 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.
- A camera can only assess a property made visible and repeatable by the inspection setup.
- Sample diversity and marginal cases determine how meaningful a feasibility result is.
- Visual inspection does not replace hidden, destructive, functional or statutory tests.
