How to Choose the Right Thermal Transfer Ribbons
Thermal transfer ribbons are essential consumables for thermal transfer label printers. When printing barcode labels in bulk, it is necessary to select the appropriate thermal transfer ribbon according to the label material to achieve the best results. So, what types of thermal transfer ribbons are available, and how should you choose the right one?
Thermal Transfer Ribbon Structure
Thermal transfer printing ribbons consist of a base film, a heat-resistant coating, and an ink coating.
The base film is usually a 4.5-micrometer-thick polyester film, whose strength and thickness directly affect the ribbon's elongation and application scope. The heat-resistant coating serves to insulate, reduce friction, and minimize dust adhesion to the print head, thereby protecting it and extending its lifespan.
Types of Thermal Transfer Ribbons
Thermal transfer ribbons are mainly divided into three types: wax-based, wax-resin, and resin-based:
1. Wax Ribbons: Containing approximately 70% wax, suitable for common paper, coated paper, and rough paper.
2. Wax-Resin Ribbons: Containing a 50/50 ratio of wax and resin, they are suitable for use on coated paper, synthetic paper, PET, PVC, and other materials.
3. Resin Ribbons: Containing less than 50% wax, they offer superior scratch resistance, smudge resistance, and solvent resistance, ideal for a variety of polyester and plastic label materials.
In terms of color, thermal transfer printing ribbons are predominantly black, but white, red, blue, green, and other color ribbons are also available.
Generally, wax ribbons are the most cost-effective, followed by wax-resin, with resin ribbons being the most expensive.
Choosing the Right Thermal Transfer Ribbon for Label Materials
Label materials can be categorized into paper, synthetic materials, and fabrics. When choosing a thermal transfer ribbon, consider the label material and the usage environment:
1. Paper Labels:
● Glossy: Mirror-coated paper, glossy paper, etc. Ideal for resin-enhanced wax or wax-resin ribbons.
● Semi-Glossy: Coated paper. Best with resin-enhanced wax and general wax thermal transfer ribbons.
● Matte: Offset matte paper. Suitable for general wax-based ribbons.
2. Synthetic Materials:
● PET (Polyester)
● PVC (Polyvinyl Chloride)
● BOPP (Polypropylene)
● PE (Polyethylene)
● PS (Polystyrene)
● Polyimide
● Metalized PET materials: such as laser rainbow film, monofilament film, and gold (high-gloss, matte) and silver (high-gloss, matte) foils.
These materials are stronger, more visually appealing, and have a wider environmental adaptability than paper-based materials, so they require higher-performance thermal transfer ribbons.
Hybrid and resin-based thermal transfer ribbons are primarily used, and the specific choice depends on the user's requirements and the usage environment.
For example, if the label only requires abrasion resistance, a hybrid thermal transfer ribbon can be selected. If there are requirements for corrosion resistance and high-temperature resistance, a resin thermal transfer ribbon is needed, and in this case, PET (180 degrees Celsius) or POLYIMIDE (300 degrees Celsius) label materials are recommended.
Thermal Transfer Ribbon Width Selection
Generally, the width of the thermal transfer ribbon should be slightly wider than the label to protect the print head. For example, if printing 65mm-wide labels, a 70mm-wide thermal transfer ribbon is typically selected.
