The new and highly developed system of single beam laser marking and inspection for printing of freshness date on beer bottle label

摘要

We have developed the new system of single beam laser marking and inspection for printing of freshness date on beer bottle label. Compared to conventional laser marking system, this new system is featured on both the minimum electric energy consumption by using single beam laser rather than area laser on engraved slit and the assurance for correctness of printing on beer label. Annual maintenance cost has been reduced by 15,000 Euro/year in application on this new system for the beer bottle packaging line because single beam laser system is based on free maintenance for a decade. The characters of this new single beam laser printing look so familiar like those of human handwriting.
