In this article, we will explore how thermal transfer ribbons are used, factors affecting printing quality, and proper storage and handling techniques. Optimise your resources by understanding the world of thermal transfer ribbons.
What is a Thermal Transfer Ribbon?
A thermal transfer ribbon is a specialised film coated with ink or wax-like substances that are transferred onto a variety of surfaces. This ribbon acts as the medium between the thermal transfer printer and the printing substrate. By applying heat and pressure, images, text, or barcodes are printed onto labels, tags, or other materials.
Types of Thermal Transfer Ribbon
Thermal transfer ribbons are available in three main types. Each type has its unique characteristics that make them suited for different applications.
Wax Thermal Transfer Ribbon
The wax variety is the most affordable option for label printing. They offer high-contrast images and offer good mechanical resistance. Wax TT Ribbon is ideal for coated woodfree, raw vellum and art paper labels. However, they are not as durable as their resin or wax-resin counterparts.
Resin Thermal Transfer Ribbon
Resin ribbons are highly durable and resistant to harsh environments, chemicals, and extreme temperatures. They ensure that the print is readable through different conditions so you will not have to reprint labels at every stage. Although it is the pricier option, the benefits bring unmatched value that can optimise your processes. The print image will be protected against scratching, smearing, liquid stains, and chemical damage so you can use it for outdoor applications or hazardous environments. They are best paired with mirrorkote labels, art paper labels, pp synthetic labels and polyester labels.
Wax-Resin Thermal Transfer Ribbon
Get the best of both worlds with Wax-Resin Ribbons. Combining the benefits of both wax and resin, wax-resin ribbons offer excellent print quality and durability at a reasonable price. They are rub-resistant which protects them from smudges and smears. They are ideal for products that are handled by many parties and still retain clear prints. Wax/Resin ribbons produce finer images when paired with labels of smoother and coated surfaces.
Advantages of Thermal Transfer Ribbons
Compared to direct thermal printing, using thermal transfer ribbons play a vital role in the quality and durability of prints.
The ink or wax-like substances on the thermal transfer ribbon ensure sharp and crisp prints with excellent clarity and legibility. By reproducing fine details and complex barcodes, ensure that they can be scanned easily to optimise productivity.
The materials used in thermal transfer ribbons, especially resin-based ribbons, offer exceptional resistance to abrasion, harsh environments, chemicals, and UV exposure. If you need labels to remain legible for extended periods, thermal transfer ribbon printing will be more long-lasting than direct thermal printing.
Thermal transfer ribbons can be used on a wide range of substrates, including paper, plastic, polyester, and synthetic materials. If you have a wide range of products that need different label substrates, using the ribbons offers a more holistic solution.
Doing Thermal Transfer Printing Right
Using the right thermal transfer printing methods and setup will help you achieve optimal results. Here are some parameters to consider before you start printing labels.
Every substrate has a distinct surface texture and porosity which will impact how they receive the thermal transfer. Selecting the appropriate ribbon for different substrates will impact the durability, legibility and smudge resistance. If you are unsure of which thermal ribbon is best suited for your use case, consult ribbon manufacturers like Gosei Imaging to invest in the right materials for your business.
When purchasing your thermal transfer ribbon, ensure that it is compatible with the thermal printer you are using. The ribbons come in rolls of different dimensions and device compatibility. The Gosei Imaging wax thermal transfer ribbon is suitable for popular thermal printer devices from brands such as TSC, Zebra, Datamax, Godex, Honeywell.
The print speed determines how quickly labels are fed through the printer. When printing many labels at once, it is important to find the right balance between print speed and print quality. Increasing the print speed may result in faster label production but could compromise print clarity and accuracy. For better print quality, it is better to opt for slower print speeds to ensure that detailed images and small fonts are transferred accurately.
Where are Thermal Transfer Ribbons used?
As long as there is a need for labels, thermal transfer ribbons are needed for durable and high-quality printing. Here are some use cases for thermal printing:
Food & Beverage
Food labels are helpful to ensure food safety and to prevent cross-contamination of common allergens. For restaurants keeping track of ingredient expiry dates or retailers checking batch codes, labels are important to ensure food safety and compliance. F&B environments can see various changes in environments from hot kitchens to deep freezing for preservation. Good quality thermal transfer ribbon techniques can make sure that the labels are clear and durable despite changes in temperature and humidity. Help your staff keep track of your items and help customers make better purchasing decisions with the right labels.
Packaging and Shipping
Products that are shipped out change hands many times throughout the supply chain. High-quality labels are needed to make sure that parcels are tracked, and information is made available through barcodes on the product at every step of the journey. Labels for fragile and hazardous materials also ensure the safety of both the goods and the staff who are handling them so customers can receive their items in great condition.
Healthcare and Pharmaceuticals
It goes without saying that getting precise information is especially crucial for the healthcare industry. Thermal transfer ribbons help to print durable labels on medical supplies and pharmaceutical products to facilitate accurate prescriptions for disease management. In hospitals, patient wristbands also have barcodes so healthcare professionals can monitor them and get information like drug allergies to keep them safe.
Warehouse and Inventory Management
For order fulfilment, businesses need a clear database of the available stock in warehouses to plan their sales and marketing strategy. With thermal-printed labels, the print will remain clear even through changes in environments like cold storage or humid warehouses. This makes inventory tracking, asset management and packing a seamless process.
How to Properly Store and Handle Thermal Transfer Ribbons
Thermal transfer ribbons, especially the resin variety, can withstand harsh environments and are UV-resistant. Even so, proper storage and handling techniques can extend the durability of the ribbons and improve print quality. Here are some tips to go further with your transfer ribbons.
