I. What Is The Thermal Transfer Ribbon?

Thermal transfer ribbon is a crucial consumable for barcode and label printers. It’s made by coating one side of a PET Base Film with meltable ink (wax, resin, or a mixture) and applying a Back Protection Layer on the other side.

A typical thermal transfer ribbon consists of several parts: Release Tab, Leader Tape, Ribbon, Trailer Tape, and Core.

The Leader Tape, positioned at the front of the Ribbon, serves for product identification and protection.

The Ribbon, our go-to functional segment of the thermal transfer ribbon, usually comprises the Top Coating Layer, Ink Layer, Inner Coating Layer, PET Base Film, and Back Protection Layer:

• The top Coating Layer enhances ink adhesion on labels, boosting resistance to environmental factors.
• Ink Layer determines the ribbon’s usage characteristics, such as chemical resistance and friction prevention.
• The inner Coating Layer ensures a smooth printing surface and consistent ink release from the base.
• PET Base Film is the carrier for all layers, which is crucial for thermal conductivity.
• The Back Protection Layer reduces wear on the thermal printhead, minimizes static electricity generation, and enhances heat transfer.

Trailer Tape, located at the end of the thermal transfer ribbon (though some may not have it), warns the barcode printer, indicating the ribbon is running out.

The Core of a thermal transfer ribbon commonly comes in paper and plastic. The primary requirement is that it must not deform and should remain stationary during printing.

II. How do Thermal Transfer Ribbons Work？

The working principle of thermal transfer ribbons primarily relies on the heat generated by the thermal print head to transfer the ink layer from the ribbon onto the printing medium (such as label paper or synthetic materials), thus achieving the printing of images and text.

The working principle involves several key steps:

1. Base Heating: When a thermal transfer ribbon passes through a thermal transfer printer, it undergoes a base heating phase. During this phase, the ribbon is positioned under the print head, which is equipped with a series of heating elements.
2. Localized Heating: The heating elements on the print head generate high temperatures by controlling the electric current and locally heating the color layers of the ribbon. Depending on the printed content, specific areas of the ribbon are heated, causing the ink in the color layer to melt into a liquid state.
3. Ink Transfer: Once the ink is heated and melted, it adheres to the printing media below the print head, typically paper or labels. Ink transfer is achieved through a process of heat and pressure, ensuring that the ink adheres securely to the surface of the printing media.
4. Curing and Cooling: The ink transferred to the printing media solidifies upon contact and undergoes cooling, forming a durable printed image. The protective layer during this process shields the ink from external influences, enhancing the durability of the print.

The working principle of thermal transfer ribbons ensures clarity, durability, and stability in printing. It finds extensive applications, especially in label printing, barcode printing, and document printing, playing a crucial role in various fields.

III. What are the different types of thermal transfer ribbons?

Many people, especially beginners, often find themselves confused by the different names for thermal transfer ribbons when they first start using them.

It’s understandable, given that thermal transfer technology has branched out significantly over the years. Different types of thermal transfer ribbons have been developed to meet various printing needs.

Let’s break them down systematically.

Classified by the main material of the ink layer

1. Wax Ribbon:

Wax ribbon is one of the most common thermal transfer ribbon types, typically used for label printing and general product identification.

The ink layer primarily comprises wax and carbon powder, making it economical, easy to use, and suitable for various label materials.

However, due to limited durability and waterproofing, it may not be suitable for certain professional applications.

2. Resin Ribbon:

The ink layer primarily comprises resin and carbon powder, offering the highest durability and resistance to abrasion, heat, and corrosion. Some formulations withstand steam pressure, while others endure washing or dry cleaning.

It’s highly suitable for applications requiring high print quality and durability, such as chemical and healthcare labels.

However, due to its higher cost, it’s typically only used in specific industries with strict requirements.

3. Wax Resin Ribbon:

The ink layer is primarily composed of wax, resin, and carbon powder, combining the characteristics of both wax and resin, providing excellent print quality and durability.

This type of thermal transfer ribbon is suitable for applications requiring a longer lifespan and higher print quality, such as manufacturing and logistics labels, balancing price, and print performance.

How do we evaluate the merits of the above thermal transfer ribbons?

Unfortunately, although the above thermal transfer ribbons have different compositions and characteristics, it’s difficult to determine which is better simply.

Because the evaluation criteria are multifaceted, including medium adaptability, sensitivity, print quality, resistance tests, application scenarios, price, etc.

Remember, there’s no best thermal transfer ribbon, only the one that best fits your needs.

Classified by Coated Side

When selecting thermal transfer ribbons, you’ll notice two options:

Coated side out (CSO) and coated side in (CSI).

These refer to the position of the ink coating on the ribbon, directly impacting how it wraps and feeds into the label printer.

Choosing the wrong coated side can lead to consequences like printing on the ribbon but not on the labels themselves. Unfortunately, many barcode printers only support one of these options.

So, before purchasing, it’s essential to know which type of thermal transfer ribbon (CSO/CSI) matches your printer.

If you’re unsure, feel free to reach out to us. Our experienced experts can provide you with the answers you need.

Classified by Printer Printhead Usage

1. Flat-Head Ribbon:

In flat-head ribbon setups, the thermal transfer ribbon lies flat between the thermal printhead and the labels, staying parallel to the label surface.

During printing, the thermal printhead applies direct heat and pressure between the ribbon and labels, causing the ink layer to transfer onto the labels.

2. Near-Edge Ribbon:

In near-edge ribbon setups, one side of the thermal transfer ribbon is positioned between the thermal printhead and labels, while the other side contacts the label surface.

The thermal printhead applies heat and pressure during printing, transferring the ink layer from one side of the ribbon onto the labels.

This arrangement is typically used in specific printers and scenarios, such as those requiring higher printing speeds or where print quality requirements are less stringent.

DNP has produced an excellent educational video on this topic.

Practice makes perfect.

V. How Are Thermal Transfer Ribbons Produced?

Sunavin has meticulously designed our production process to guarantee that every roll of thermal transfer ribbon meets the highest standards of excellence.

STEP 1. Base Material Preparation:

The process begins with the preparation of the base materials.

The choice of substrate should consider its heat resistance, smoothness, and chemical stability.

This includes PET film (Polyethylene Terephthalate) and a mixture of resin, wax, carbon black, and various additives.

These materials are essential to ensure the ribbons’ quality, durability, and performance.

STEP 2. Coating:

Next, preparing the thermal transfer coating is essential.

The coating formulation process requires thoroughly mixing various components to form a stable solution.

The coating solution is then even applied to the substrate surface.

Coating can be done using methods like roller coating, spraying, or other suitable techniques.

Sunavin utilizes state-of-the-art automatic coating technology. The coating solution is uniformly coated onto the PET film. This advanced technology ensures consistent thickness and quality across the entire length of the ribbon.

We chose 4.5um film as the substrate and employed advanced roller coating technology to apply key layers evenly onto the PET Base Film.

These layers include PET Base Film, Inner Coating Layer, Ink Layer, Top Coating Layer, and Back Protection Layer. Each layer is carefully designed to enhance the performance and printing quality of the final product.

Feeling familiar? You’re right; these were mentioned earlier. Now, let’s delve into the role of each layer:

PET Base Film	The foundation of the thermal transfer ribbon is PET Base Film, a transparent and elastic material capable of withstanding stress under high temperature and pressure. The selection of this layer directly impacts the stability and durability of the thermal transfer ribbon.
Inner Coating Layer	Located between the Ink Layer and PET Base Film, the Inner Coating Layer interacts with the thermal printhead’s heat energy, allowing the pigments in the Ink Layer to release appropriately and transfer to the printing surface. The Inner Coating Layer provides protection and stability to ensure print quality.
Ink Layer	The core of the thermal transfer ribbon is the Ink Layer, containing the actual printing pigments. The material and quality of this layer directly affect the clarity and stability of printing. Common materials for the Ink Layer include resin and wax, which melt quickly at high temperatures and adhere to the printing material.
Top Coating Layer	The Top Coating Layer is the surface layer of the thermal transfer ribbon, responsible for receiving the heat energy from the thermal printhead and transferring it to the printing surface. This layer typically consists of materials resistant to high temperatures and abrasion to ensure clear and durable printing effects.
Back Protection Layer	At the bottom of the ribbon, the Back Protection Layer is designed to protect the PET Base Film from damage during use. This layer usually possesses excellent wear resistance and corrosion resistance, ensuring a longer lifespan for the thermal transfer ribbon.

 

STEP 3. Cooling & Drying:

After applying the coating, the film must undergo a cooling and drying process to form a stable structure.

The coated film passes through a series of drying ovens where the solvents in the coating evaporate, leaving a solid layer of thermal transfer material on the film. The temperature and speed of the drying process are carefully controlled to avoid any defects, such as bubbles or uneven surfaces.

This step is crucial to stabilize the coating and ensure it adheres properly to the PET film without any imperfections.

Once dried, the film is cooled to room temperature to stabilize the coating before moving to the next stage.

STEP 4. Slitting & Rewinding:

Now cooled and dried, the coated film is subjected to slitting and rewinding.

During this step, the wide master rolls of coated film are cut into narrower rolls according to the required ribbon widths.

This slitting process is precise and tailored to meet various customer requirements for different ribbon sizes. After slitting, the narrower rolls are rewound onto smaller cores.

This step requires meticulous attention to maintain the tension and alignment of the film to prevent any wrinkles or inconsistencies in the final product.

STEP 5. Finished Rolls:

The slitted and rewound ribbons are now in the form of finished rolls. Each roll is inspected for quality assurance to meet the specified standards.

This includes checking for any visual defects, measuring the ribbon length and width, and testing the print quality. Any rolls that do not meet the quality criteria are rejected or reprocessed. The finished rolls are then labeled with product information and batch numbers for traceability.

STEP 6. Packaging & Boxing:

The final step is packaging. The finished thermal transfer ribbons are carefully packaged to protect them during transportation and storage. They are then boxed and prepared for shipment to customers.

Next, let’s talk about mineral oil.

Mineral oil (MOH) is a hydrocarbon mixture derived from petroleum, mainly consisting of saturated hydrocarbon mineral oil (MOSH) and aromatic hydrocarbon mineral oil (MOAH). MOH, especially MOAH, has potential carcinogenic and mutagenic properties and can pose health risks to humans through various pathways such as environmental pollution, lubricants in food processing machinery, production aids, food additives, and food contact materials, attracting attention from various countries.

Printed paper products are considered to have a high risk of mineral oil exposure to the population because mineral oil is a typical raw material for almost all types of offset printing inks (solvents for the resin used as adhesives). Therefore, several countries have begun to restrict and monitor the mineral oil content in paper products.

In short, mineral oil is a harmful substance that used to be one of the main components in manufacturing thermal transfer ribbons.

Now? Sunavin says “No!” to mineral oil.

Our latest manufacturing process utilizes green, non-polluting synthetic oils as substitutes for mineral oil, primarily including poly-alpha olefins or liquid paraffin. These alternatives may offer similar performance and functionality while potentially being more environmentally friendly and health-safe.

Sunavin is leading the way in green and sustainable development.
