Key Benefits of Pre-Register

1. Reduced Setup Time：Pre-registration ensures that the printing plate of flexographic printing press is accurately aligned during initial setup, significantly reducing preparation time. This allows operators to start production more quickly, improving overall work efficiency of flexo printing machines.
