In packaging industry, the printing quality is one of the most important criteria. Before developed vision system to serve the industry, eyes visual inspection was used. This resulted in lots of problems due to the physical and mental fatigue experienced by workers leading to unstable checking result. There were cases where the shampoo plastic bottle was rejected and increased in production cost. The workers also take a longer time of 30s in the quality checking process.
