Print inspection separates OCR reading, OCV content checks, colour registration and appearance defects. Colour, substrate reflections and font changes affect imaging. Continuous film and individual packages need different triggers and transport designs.
How to validate
Provide approved artwork, tolerances, minimum fonts, colour requirements and speed. Build separate sample sets for incorrect or missing text, duplicate codes and misregistration. Quantitative colour acceptance needs calibrated illumination and an appropriate measurement method.
This is a general industrial-vision evaluation guide, not a delivered IRIS ANT PCBA AOI case study or a standard machine configuration. The station must be qualified for the parts, optics and automation requirements.
Project evaluation checklist
- Define the item, visible inspection surfaces and minimum defects; separate appearance, internal structure and electrical or functional checks.
- Prepare verified good, defective and borderline samples across lots; separate training and acceptance sets.
- Report escapes and false calls by defect class, with review workload, complete cycle time and repeatability.
- Confirm program versions, permissions, retention and traceability fields; approve production only after trials pass.
