For a long and lasting mark on your labels, thermal transfer is the best option. We sell a variety of ribbons for every application.
There are three basic types of ribbons:
Wax Ribbon:
Works well for printing on paper labels.
Wax/Resin Ribbon:
Works well for synthetic materials, and applications that endure alcohol wipe downs and other vigorous cleaning processes.
Resin Ribbon:
Works best for printing on Mylar and applications where the labels will be placed in a high temperature atmosphere.
