What are the key factors in choosing a thermal transfer ribbon (TTR)

When selecting the right ribbon for your application, consider the following:

  1. Ribbon Width

The ribbon should be wider than the label material to protect the printhead from abrasion.
Example: A 70mm wide label requires an 80mm wide ribbon.

  1. Ribbon Type
  • Wax – Most cost-effective; ideal for porous materials like uncoated paper. Best for indoor use (e.g. shipping or pricing labels).
  • Wax/Resin – More durable; suited for coated papers, tags, and films. Offers resistance to smudging and mild chemicals. Can be used outdoors short-term.
  • Resin – Most durable and chemical-resistant; best for synthetic materials like polyester or polyimide. Suitable for demanding environments.
  1. Wind Configuration – Specify your printer brand to ensure correct ribbon winding—ink side in or ink side out.
  2. Printer Core Diameter – Make sure the ribbon matches the core size required by your printer. Some cores include slots that fit specific feed mechanisms.
  3. Roll Length – Check your printer’s maximum roll diameter. Oversized rolls may be too heavy or physically incompatible with your printer.
