Three chemistries
Wax ribbons are economical and suit paper labels. Wax-resin ribbons resist smudging and suit coated papers and most packaging films. Resin ribbons withstand heat, chemicals and abrasion and are used on synthetics.
Flat-head and near-edge
Label printers generally use flat-head printheads; TTO units use near-edge heads that release the ribbon immediately. Each needs its own ribbon grade.
Match the substrate
Smooth films give the best transfer. Rough or treated surfaces may need a softer ink. Always test adhesion after the pack has cooled.
Size it correctly
Choose a ribbon slightly wider than the print and as long as the printer accepts, to reduce changeovers.
