Description

Technical Field

[0001] This invention relates to the technical field of crystal labeling machines, and in particular to a flow roller system for crystal labeling machines. Background Technology

[0002] Currently, there are roughly three types of crystal label printing. The first type involves inkjet printing on the printing medium followed by lamination with a transfer film. The second type has a protective film covering the original printing medium; before inkjet printing, the protective film is removed; after inkjet printing, the printing medium is laminated with a transfer film. The third type involves hot stamping the printing medium after inkjet printing, and finally laminating it with a transfer film. These three crystal label printing processes have different routes and use different transfer roller systems; therefore, each process requires a dedicated crystal label printer. Current technology does not offer a solution to integrate these three processes into a single crystal label printer. This significantly limits the applicability of a single crystal label printer.
