Ever found yourself in a situation where you needed to label a product, but you couldn’t just slap on a paper sticker? That’s where thermal transfer barcode ribbons come into play. These special ribbons have been gaining traction in various industries, from retail to logistics, due to their exceptional durability and high-definition print quality. But what exactly is a thermal transfer barcode ribbon, and how can you choose the right one?
What is a thermal transfer barcode ribbon?
A thermal transfer barcode ribbon is a printing technology used for printing product labels with barcodes. This technology utilizes a thermal transfer roller made of a transparent plastic film/ribbon. One side of the ribbon is coated with ink made of wax or resin.
TT barcode ribbons require the use of a TT barcode printer to print labels. The printer consists of two main printing components – the drum roller and the print dots/pins.
- The drum roller transports the ribbon from the spool onto the label.
- The coated side of the ribbon faces the label, while the backside presses against the drum and the print head.
- The dots on the print head heat up the coating and transfer the ink onto the label.
Types of thermal transfer barcode ribbons
With advancements in technology and materials science, thermal transfer technology has seen some innovations, such as variations in the chemical composition of the coating. Different types of coatings are needed to meet the requirements of various industries.
Based on the coating, TT barcode ribbons can be classified into three categories:
- Wax Coating: As the name suggests, this ribbon coating is entirely made of wax. It offers clear printing results at a low cost. However, these are the least durable printing material types. While they have better resistance to fading compared to direct thermal printed labels, they are prone to scratches and smudges. They are also susceptible to chemical damage, severely limiting their practicality in various scenarios. Nonetheless, due to their cost-effectiveness, they still occupy a significant portion of the market (approximately 70%).
- Resin Coating: These ribbons are primarily made of ink resin, but they may contain traces of wax. Resin coatings surpass wax in terms of durability, temperature resistance, and image quality. Additionally, they are compatible with various surfaces. However, their manufacturing cost is much higher than wax ribbons. This means that unless necessary, most consumers would avoid using them.
- Wax-Resin Coating: This type of ribbon features a coating made of a mixture of wax and resin, which helps eliminate static on the ribbon, resulting in sharper edges. Wax-resin coated ribbons are more durable than wax-coated ribbons but cheaper than pure resin-coated ribbons. Due to their affordability and high durability, they serve as a good choice for implementation in various scenarios. They can withstand scratches, smudges, and moderate levels of chemical damage.
How to determine the most suitable thermal transfer ribbon for your needs
When selecting a thermal transfer barcode ribbon for your labels, you need to consider a few factors:
- Durability: The first factor to consider is the durability of the coating. While approximately 70% of label printing uses wax-coated ribbons, they are susceptible to scratches, smudges, high temperatures, and chemical damage. On the other hand, resin-coated ribbons have strong resistance to damage and chemical exposure. Therefore, depending on your product and whether there is a risk of chemical exposure and high temperatures, wax-coated ribbons may be the best choice for you.
- Cost Considerations: As mentioned earlier, resin-coated ribbons are suitable for almost any type of label, so why not choose them directly? The answer is cost. Using resin significantly increases your production costs compared to wax. Therefore, if your label requirements can be met with wax barcode ribbons, there is no need to look for alternatives.
- Label Material: Another thing to keep in mind when selecting barcode ribbons is the material of the barcode labels you will be printing on. Different types of ink coatings are compatible with different types of labels. The table below lists different label materials and the compatible coatings.
|Label Material||Wax Coating||Wax-Resin Coating||Resin Coating|
|Paper Label Stocks||✓||✓|
|PVC Shrink Wrap||✓||✓|
Carbon Ribbon Coating Orientation
Different manufacturers may apply the coating on both sides of the ribbon. Based on this, there are two types of thermal transfer ribbons: Coating Side In (CSI) and Coating Side Out (CSO). Your label printer may support one of these types. Therefore, before selecting a ribbon, check your label printer specifications to determine the type of thermal transfer ribbon it uses.
In comparison to labels and printers, the size of the ribbon is another important factor. In simple terms, ensure that the width of the ribbon is close to the width of the label but slightly wider. This ensures full coverage of the label while minimizing ink waste.
Thermal transfer ribbons come in different lengths, and the length of the ribbon you choose depends on your printing volume. For example, shorter lengths of ribbons are typically used for desktop applications. However, if you’re doing industrial-grade printing, it is advisable to use ribbons with a length of approximately 300 meters.
Thermal transfer ribbons are wound on cylindrical plastic cores. While most printers use a standard 1-inch core, it is essential to check the specifications of your printer and select a core size that is compatible with it for safety purposes.
Tips for Using Thermal Transfer Barcode Ribbons
We are confident that you are a knowledgeable professional, but caution is never a bad thing. Therefore, here are some simple tips and practices to ensure a smooth label process.
Regularly clean the printer
Make sure to periodically clean the interior of your thermal transfer printer to prevent the accumulation of dust and fibers, which can increase static formation in label paper. This helps maintain consistent image quality and optimal printer functionality.
Set the optimal speed and heat settings
The working principle of a thermal transfer printer involves heating the ink coating on the ribbon and then pressing the ribbon onto the label paper. Clarifying three crucial factors that determine print quality:
- Coating temperature
- Pressure of the ribbon against the print head and label
- Speed of the ribbon and label
Printing at lower speeds, temperatures, and pressures extends the life of the print head. However, these settings need to be adjusted based on the darkness of the print, label material, and coating type.
Clean the print head
With regular use, the print head eventually accumulates black residues formed due to friction between the print head and the ribbon. This buildup can result in black lines appearing on the labels, decreasing print quality. Therefore, it is essential to clean the print head every time you change the ribbon or label roll. Use a print head cleaning pen or a cotton swab dipped in isopropyl alcohol.
Avoid creases in the ribbon
Any creases on the ribbon hinder proper contact between the ribbon and the label, leading to poor print quality. Prevent this situation by regularly cleaning the waste ribbon from the garbage collection tray.
Additionally, if you notice diagonal creases in your ribbon, it may be due to excessive heat. In that case, reduce the speed and temperature until you achieve the same print quality.
Use the printer’s tear-off bar
After printing, use only the built-in tear-off bar or scissors provided by the printer to cut the printed labels. Using any other tools like a paper cutter, surgical blade, or blades may damage the drive rollers, further deteriorating print quality.
Calibrate after installation
For complex machines like printers, they need to perform multiple tasks at the right time. Regular calibration is necessary. Therefore, it is recommended to calibrate the printer each time you install a new ribbon roll or label/media roll.
Use a ribbon wider than the roll
As mentioned earlier, always ensure that the width of the ribbon is greater than the width of the label. This is done to ensure even wear of the print head and drum during
Characteristics and Uses of Thermal Transfer Barcode Ribbons
From durability to flexibility, thermal transfer barcode ribbons offer several noteworthy characteristics. They’re resistant to smearing and scratching, and they provide high-definition prints that are easy to scan. This makes them the go-to choice for product identification, tracking, inventory control, and regulatory compliance, among others.
