Thermal Transfer Ribbon: Types, Sizes and Buying Guide

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!

In this article, we will provide you with the best guide to thermal transfer ribbons, explain the basics, and guide you through the various aspects of this special ribbon. Let’s get started with understanding exactly what these ribbons are.

What Are Thermal Transfer Ribbons?

Thermal transfer ribbons, or simply referred to as “thermal ribbons” or “thermal films”, are typically made from a thin polyester film with a thickness of 3-6 microns, coated with inks on one side. The ink coating ingredients typically contain wax, resin, or a blend of both, mixed with carbon black, color pigments, and additional additives.

The ribbon is placed between the print head and the materials ot be printed on. When the ribbon passes through the printer, the heat from the print head melts the ink, transferring the ink onto various materials, such as paper, labels, or synthetics, to create desired images and text.

Since thermal ribbons help create high-quality, long-lasting prints for barcode labeling, product packaging, shipping labels, industry tags, and other applications. They become an essential printing consumable in industries such as manufacturing, logistics, garment, healthcare, retail, and many more.

Let’s take a closer look at the structure of the thermal ribbon film in the following section.

What Are The Structures of A Thermal Transfer Ribbon?

Different layers of thermal transfer ribbons

A thermal transfer ribbon is typically a polyester film coated with multiple layers. You can think of it as 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.

Different thermal ribbon manufacturers, such as DNP, Rioch, Zebra, and Kura, use different coating formulations for the ribbons to adapt to different printing requirements. The most challenging part of thermal ribbon manufacturing is keeping a balance between high performance, stable quality, and affordable costs. This is the core value of the thermal ribbon business and the key factor that sets outstanding manufacturers apart from the competition.

What Are the Common Types of Thermal Transfer Ribbons?

Thermal transfer ribbon comes in different types, each designed for specific printing needs and material compatibility. The common types 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

Wax-resin ribbons, also known as hybrid ribbons, are a premium blend of wax and resin, ensuring a harder print than normal wax thermal ribbons. It offers better resistance to smearing and is ideal for semi-gloss paper and some synthetic materials.

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 make use of a full resin formulation. They are designed for harsh environmental conditions and are most resistant to smudging and scratching. 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 quick comparison of these three common types of ribbons:

What Are the Common Thermal Transfer Ribbon Sizes?

Thermal transfer ribbon size is expressed as “Width (mm) x Length (m)“. While many different ribbon sizes are available on the market for various printer types and applications, we have compiled a list of popular ribbon sizes for your reference.

Ribbon Width

Thermal ribbon width generally ranges from 40 mm to 220 mm to suit different printing applications. Common widths include 40 mm, 50 mm, 55mm, 60 mm, 76mm, 80 mm, 90 mm, 100 mm, 110 mm, 152 mm, 160 mm, 220 mm, etc. Among them, the 110mm (4.33 inches) thermal ribbon width is the most popular one because it can be used to print standard 4″ x 6″ shipping labels in most desktop label printers.

However, it is important to note that the selected ribbon width must be slightly wider (typically 2-5 mm) than the corresponding label width to ensure the ribbon fully covers the labels and prevents damage to the printer head. For example, if your label is 80mm wide on an 83mm wide backing paper, then you should choose a ribbon width of at least 85 mm.

Simply buying the widest ribbon for your printing work is also not advisable, as it would lead to significant waste. To choose the right ribbon width, consider the size of the labels you’ll most commonly use and buy ribbon that’s 2- 5 mm wider than these – this is the wisest method we recommend for you.

Ribbon Length

Ribbon lengths are usually determined by the printer. Desktop printers typically use ribbon lengths of 74 m, 91 m, 110 m, and 300 m, while industrial printers and automatic labeling systems typically use ribbon lengths of 300 m, 360 m, 450 m, and 600 m.

Longer ribbons can obviously reduce the frequency of ribbon changes, which means less downtime and improved productivity between your print jobs. You can easily calculate how many labels you’ll be able to print from a particular ribbon length with our free thermal transfer ribbon label calculator. Consider buying the longest length that will fit into your label printer – the result? It saves you time and money.

Core Size

Ribbons use paperboard or plastic cores to support the rolls and ensure smooth rewinding inside the printer. Unlike thermal labels using 1′, 1.5″, and 3″ cores, thermal transfer ribbons typically use two types of cores: 1-inch (25.4 mm) cores for desktop and industrial printers and 0.5-inch (12.7 mm) cores for compact printers. The cores can be smooth or notched, single or dual, depending on the ribbon specifications.

Winding Direction

Thermal transfer ribbons usually come in two winding directions:

• CSO (Coated Side Out): The ribbon is wound around the core, and the ink side of the ribbon faces outward. Most barcode printers like Zebra, TSC, Intermec, Bixolon, and Printronix typically use CSO ribbons.
• CSI (Coated Side In): The ribbon is wound inside the core, and the ink side of the ribbon faces inward. SATO, Datamax, and some other printers usually use CSI ribbons.

While most ribbons are CSO, some printers require CSI ribbons. Don’t forget to verify the winding direction before you make a purchase; otherwise, your ribbons and labels simply don’t print.

Here is a brief summary of thermal ribbon sizes for your reference.

FAQs About Thermal Transfer Ribbon Problems

1. Are there only black thermal transfer ribbons?
No, there are colored thermal ribbons (white, red, blue, yellow, etc) as well as black. It actually depends on the colors you want to print on your materials.
2. Why are my prints faded or difficult to read?
Chances are, your label and ribbon just don’t match. Try switching to the right ribbon type. The general rule is this: paper matches wax ribbons, tougher labels match wax-resin or all-resin ribbons. If it still isn’t clear, then try slowing the print speed. Sometimes, a simple head cleaning using rubbing alcohol or a cotton swab will solve the problem.
3. Why does my ribbon get wrinkled or sticky?
If it is piling up or getting stuck, it is probably not loaded straight, or there’s gunk in the ribbon path. Spool it out, flat-set it, and make sure it feeds smoothly. Still stuck? Check for scraps or dust. Because even a speck can mess things up. If you find the ribbon is wrinkled, discard it and replace it with a fresh one. If the problem won’t quit, perhaps your printer is at fault. You can consult your printer support or give us a shout in the comments section below.
4. Can I use any ribbon in my printer?
No, not every ribbon will work on every printer. Ribbons from different manufacturers have different ingredients in them, and printers from different brands have different heating temperatures and mechanisms. Check your printer manual before you print. Always conduct a test label printing before beginning a big job.
5. How do I store my ribbons to keep them lasting?
Don’t leave ribbons out in the sunlight or in a damp basement. Keep them in a dry, cool place and sealed up until you use them. If you handle them, try to keep your hands clean. Oils and dust will also wreak havoc on the print.
