Reference approach
Use controlled colour imaging and representative labelled samples to compare visible leaf or blend appearance. Keep class definitions tied to the quality team's reference standard.
What a pilot should establish
- Test supplier and batch variation, presentation thickness and borderline reference grades.
- Agree the pass, fail and uncertain outcomes before testing. Record incorrect accepts and incorrect rejects separately using an independent sample set.
Appearance is not a direct measurement of chemical composition or nicotine content.
Outputs and line integration
Define the result required by the next process step, the time available to return it and the action for an uncertain result. Where records are needed, keep the image and decision tied to the inspected item or handling event.
Technical reference
Share reference grades, batch samples and sample-presentation method. We can define the imaging approach, integration points and a sample-based validation plan.
