Golden Template

An important topic in flexo printing is the Golden Template Comparison. A Golden Template is a master image that is captured by the inspection system when the press is running good copy. Every printed repeat is compared to that original Golden Template. High-performance software and hardware is needed to track movements in the print direction and compensate for web stretch, as well as to make accurate comparisons between printed output and the target on the fly. There are two important benefits of a Golden Template. First, it results in a fixed reference with a stable, repeatable quality. Secondly, it is more sensitive to slow-growing defects such as register, streaking, and color changes.
