Setting Appearance Limits for Coated Glass is best approached as a measurable packaging decision, not a visual preference. A reference image communicates direction, not an acceptance standard. Define colour with a physical master or colour system, then add gloss, opacity, gradient limits, artwork position and coverage boundaries. Evaluate samples under agreed lighting and against the same background.
Sequence processes deliberately
Coating, frosting, screen printing, hot stamping and metallisation each add tolerances and adhesion risks. Confirm the process order, masking areas and curing conditions. Multi-process decoration should be tested as the final stack because individually acceptable layers may not perform well together.
Build appearance limits before bulk
Create boundary samples or photo standards for colour variation, pinholes, dust, print registration, scratches and edge coverage. Tie these defects to critical, major and minor classifications. A beautiful golden sample is useful only when production inspectors also know the permitted limits around it.
