If you’re here, this means you’re curious about barcode clarity and print longevity, and more specifically – thermal transfer ribbons. Do you find yourself lost in the terminology of wax, resin, or wax-resin ribbons? Unsure which type suits your printing needs? Fear not! We’re here with the best guide to thermal transfer ribbons, answering your questions and guiding you through the various aspects of this special kind of ribbons.

In this article, we will provide you with full information on how thermal transfer ribbons work, the different types available, and their advantages and disadvantages. Let’s get straight into it, starting with understanding exactly what these ribbons are.

What is a Thermal Transfer Ribbon (TTR)?

What is thermal transfer ribbon
Thermal transfer ribbon (TTR), often simply referred to as “ribbon,” is a critical part of thermal printing. It is a component used in thermal transfer printers to print desired images or barcodes onto various materials like labels, paper, plastic, or fabric. With help from a thermal printhead, the printer precisely melts the wax or resin from the ribbon onto the label surface to create a durable print.

These ribbons play a crucial role in ensuring high-quality, durable prints for labeling and barcoding applications across various industries such as manufacturing, logistics, healthcare, retail, and more.

Choosing the right type of ribbon for your specific application is essential in achieving the desired print quality and longevity of the labels. But before going to that part, let’s see how the structure of a transfer ribbon looks and behaves.

The Structures (Different Layers) of Thermal Transfer Ribbons

Structures of TTR
A thermal transfer ribbon is like a tiny sandwich; it consists of several layers to facilitate efficient heat transfer and ink transfer onto the desired substrate. Here are the typical layers found in thermal transfer ribbons:

  1. Back Coating: This is the outermost layer that faces the printer’s thermal print head. It is a heat-resistant coating that protects the ribbon from abrasion and static buildup. Common materials used for this layer include silicone, polyester, or ceramic-based coatings.
  2. Base Film Layer: This layer serves as the foundation or carrier for the other layers. It is typically made of thin, flexible materials like polyethylene terephthalate (PET), polyethylene naphthalate (PEN), or polyimide. The base film provides mechanical strength and dimensional stability to the ribbon.
  3. Release Layer: This layer is applied between the base film and the ink layer. It facilitates the smooth release of the ink during the printing process. Common materials used for the release layer include waxes, silicone-based compounds, or specialized polymers.
  4. Ink Layer: This is the most crucial layer, containing the pigments or dyes responsible for transferring the image or text onto the substrate (e.g., paper, fabric, or plastic). Depending on the intended application and substrate, the ink layer can be composed of various materials, including wax, resin, or a combination of both.
  5. Top Coating (Optional): Some thermal transfer ribbons may include an additional overcoat layer on top of the ink layer. This layer provides protection against abrasion, chemical resistance, and enhanced durability for the printed image or text.

The specific composition and thickness of each layer can vary depending on the manufacturer and the intended application of the thermal transfer ribbon. These layers work together to ensure efficient heat transfer, consistent ink release, and high-quality printing results on various substrates.

3 Common Types of Thermal Transfer Ribbon

Common Types of Ribbons
Thermal transfer ribbons (TTR) come in different types, each designed for specific printing needs and material compatibility. The common types of TTR are wax, wax/resin, and resin ribbons. Here’s an explanation of each type:

1. Wax Ribbons

Wax ribbons use a standard wax base, which is best suited for paper material due to their lower smudge resistance. They are made of wax-based ink that is transferred onto paper or other materials through the use of heat, usually from a thermal transfer printer.

They are perfect for general use and offer the lowest price of thermal ribbons.

To be more specific, they are used for printing barcodes, labels, and other types of high-volume printing applications. The wax-based ink used in these ribbons provides a durable and long-lasting print, making them ideal for industrial and commercial uses.

2. Wax-Resin (Hybrid) Ribbons

A wax resin ribbon is a premium blend of wax and resin, ensuring a harder print than wax thermal ribbons. It offers better resistance to smearing and is ideal for semi-gloss paper and some synthetic materials.

Wax-resin ribbons, also known as hybrid ribbons, are a type of thermal transfer ribbon used in barcode and label printing. They are a combination of wax and resin materials, which makes them more durable and resistant to wear and tear compared to standard wax ribbons.

This makes them suitable for applications requiring more durable and long-lasting labels, such as outdoor labeling, shipping and logistics, and asset tracking.

3. Resin Ribbons

Resin thermal transfer ribbons, often referred to as ‘durable resin’, make use of a full resin formulation. They are designed for extreme environments and are most resistant to smudging and scratching.

These ribbons are made of a special type of ink, which is a resin-based material that has a high degree of durability and resistance to harsh environmental conditions. These ribbons are characterized by their composition, which includes a higher percentage of resin compared to wax or wax-resin ribbons.

Resin ribbons are designed for use in applications where labels need to be able to withstand exposure to extreme temperatures, chemicals, and abrasion. This makes them ideal for use in industries such as healthcare, automotive, and manufacturing, where labels need to remain readable even in challenging conditions.

Here is A Table Comparison for the 3 Types of Ribbons

Label MaterialsBest for paper and some coated paper labelsWorks well on both paper and synthetic materialsBest for synthetic materials like polyester, vinyl, and polypropylene
ApplicationsGeneral-purpose printing: shipping labels, warehouse labels, retail labelsApplications requiring more durable prints: asset tracking, shelf labelingHigh-durability requirements: chemical drum labeling, outdoor applications
AdvantagesCost-effectiveGood balance between cost and durabilitySuperior durability and resistance to harsh conditions
DisadvantagesLower resistance to abrasion, chemicals, and extreme temperaturesNot as durable as pure resin ribbonsHigher cost compared to wax and wax/resin ribbons

While the three mentioned types are the primary categories of thermal transfer ribbons, there are also variations within these types, catering to specific needs. Some additional considerations are:

Color ribbons

Color Ribbons

  • Color Ribbons: Vibrant prints, perfect for colorful labels.
  • Near-Edge Ribbons: High-speed precision for efficient printing.
  • Textile Ribbons: Durable prints for fabric labels.

What Is CSO And CSI?

CSO and CSI Ribbons

CSO (Coated Side Out) and CSI (Coated Side In) are two terms explaining the orientation of the coating that is done on a thermal transfer ribbon. For instance, Zebra printers often use CSO-oriented ribbons and cater to a broad range of industrial thermal transfer applications.

CSO Ribbons:

  • The ink coating is on the outer side of the ribbon roll, facing away from the core.
  • When loaded, the ribbon unrolls from the bottom, with the coated side facing outwards towards the label or substrate being printed on.
  • Common in printers like Zebra, TSC, and some Datamax models.

CSI Ribbons:

  • The ink coating is on the inner side of the ribbon roll, facing towards the core.
  • When loaded, the ribbon unrolls from the top, with the coated side facing inwards towards the label or substrate.
  • Commonly used in printers like Datamax, Sato, and some older models.

Ink Coating PositionOutside of the ribbon rollInside of the ribbon roll
WindingInk side faces outwardInk side faces inward
Printer CompatibilityUsed in printers configured for CSO ribbonsUsed in printers configured for CSI ribbons
Common UsageMany desktop and industrial printersSpecific models of printers, depending on the manufacturer

The key difference is the direction the coated side faces when the ribbon is loaded into the printer. This orientation ensures that the ink coating makes direct contact with the substrate during printing for proper ink transfer and high-quality output. So, make sure you get clear info on these “little things” while checking the thermal rolls or transfer ribbons for yourself.
