Thermal Transfer Ribbons 101
What is Thermal Transfer Printing?
Thermal printing is an on-demand printing technology where there is a transfer of ink from a base film (ribbon) to a label substrate using heat, pressure, and speed. Thermal Transfer Printing requires a Thermal Transfer Printer, Thermal Transfer Ribbon, and Thermal Transfer Compatible Label Stock.
Direct Thermal Labels do not require a Thermal Transfer Ribbon to print. A printer applies heat directly to the heat activated label.
- Direct Thermal material requires a higher heat for printing than Thermal Transfer.
- A print head will burn out faster as there is no buffer (ribbon) to keep the label from contacting the print head.
Thermal Transfer Labels require a Thermal Transfer Ribbon to transfer ink from the ribbon to the label. Printing with thermal transfer materials requires less heat than printing on direct thermal.
- Printheads will last longer with thermal transfer printing as the ribbon works as a buffer and protects the printhead from the label material.
- More versatile – will work with more applications than direct thermal
What is a Thermal Transfer Ribbon?
Thermal Transfer Ribbon Construction
Ink Layer: Creates the printed image
Primer: Bonds the ink to the base film
Base Film: PET – polyethylene terephthalate
Back-coat: Lubricating agent that protects the printhead
There are three types of Thermal Ribbon Formulations:
Wax (Also known as Resin Enhanced Wax)
- Prints at high speeds
- Produces dark and durable images
- Can print on flood coated labels
- Used 75% of the time
- Prints on a wide variety of label stocks
- Highly scratch and smudge resistant
- Requires more heat than printing with a wax ribbon
- Produces excellent barcodes and variable images
- Higher durability than wax or wax/resin ribbons
- Compatible with a vast array of substrates
- UL recognized
- Heat resistance is typically over 250°F
- Requires more heat than when printing with a wax or wax/resin ribbon
Questions to Ask Your Customer When Selecting a Thermal Transfer Ribbon:
- What is the make and model of the thermal printer being used?
- What is the application and what is the expectation?
- What is the label material and size?
- What type of ribbon is currently being used; wax, wax/resin or resin?
- What is the ribbon volume? How many labels used per day/week/month?
