Checklist / GuideEquipment acceptance checklist

A technical checklist for turning supplier claims into acceptance evidence.

Discuss acceptanceChecklist / GuideUV defect checklist

Classify defects by likely production layer.

Discuss defectsChecklist / GuidePrint production loss map

Find where production loses money.

Discuss loss mapDefect / ProblemRecurring UV print defects?

Classify banding, adhesion, curing, color drift and material-mode issues before changing random settings.

Review UV defect checklistDefect / ProblemColor does not repeat?

Find whether drift comes from calibration, ICC, RIP mode, material, curing, operator routine or weak QC gates.

Review ICC and RIP riskDefect / ProblemRIP or ICC issue?

Check queues, presets, profiles, material modes and operator overrides before production normalizes unstable settings.

Map production workflowDefect / ProblemProduction is leaking money?

Map reprints, waste, downtime, setup delays and claims to the technical and workflow causes behind them.

Review loss mapDefect / ProblemFinal sign-off is close?

Check whether the machine is ready for real jobs before acceptance becomes an internal production problem.
