Labels for thermal transfer
Thermotransfer Etiketten - Labels that can be transferred thermally are among the most well-known and popular kinds of labels . They're well-known for reasons. They print a clear image that's consistent in its quality. They are therefore ideal for barcodes, shipping labels and a myriad of other labels that benefit from these advantages.
Labels that are suitable for printing with thermal transfer are printed using the Ink Ribbon ( this printing method is called thermal ). The thermal paper's thermosensitive character is apparent on their surface due to their distinctive coating. When heated , the paper turns brown and the image is being printed ( direct print using thermal technology ). The punctiform heat is released by tiny heaters (dots) which are situated within the printing head. The size and arrangement of the dots determines resolution of the print. Resolution is measured in dpi (dots per inch). The main distinction is made between two printing methods that include thermal transfer printing and direct printing. Each of them has advantages and disadvantages.

Ribbon to print with thermal transfer
When printing using thermal transfers the ribbons used for thermal transfers apply the color on the label. The tape is made up of two layers: a film and an ink layer that's sensitive to heat. When printing, the various heating elements of the printer head get heated, which then transfer the dye from to the paper that is being printed. This produces high-resolution. Based on your needs, thermal transfer ribbons with different properties are readily available. The resistance of the ribbons differs with respect to scratching and smear, as well as their transparency. Scratch and smudge resistance affects durability/readability and resistance to solvents. Quality of the labels is determined by materials that is used to make the label and also the compatibility of the label to thermal transfer ribbons and printer. Ribbons are made of wax resin, wax, or mixture of wax and resin.
The differences in thermal transfer printing. Direct thermal printing
Most label printers can print with both methods - and thermal transfer printing and directly thermal printing. What is the main distinction between these two processes and what are the advantages of each method?
Labels printed with thermal transfer
Both methods are based on the same idea. The effect of heat on the tiny dots on the print head causes discoloration. When printing using thermal transfers the ink used for printing is transferred (transferred) from ribbons onto labels that are blank. Printing requires three components including the label as well the ribbon and a printer. When printing, dots form tiny spaces on the ribbon. This makes the ink melt, and then stick to the label underneath or move through it. The ink that's transferred cools and appears as sharp images. The resistance to smudge and scratching, and the durability over time of the label are determined by the type of material that is used to make the label as well as the type of ribbon.
The main benefit of printing using thermal transfer is the superior resolution and high-contrast and sharp results, and the longer life span as well as resistance against external influences such as UV radiation and cold/heat and the effects of friction or moisture. Furthermore, printing with ribbons is relatively low-maintenance. However, printing can only be done with a limited number of shades since ribbons are available in various (special) colors. However, this shouldn't be a problem for barcode labels , you can choose from our extensive label portfolio of (multi)colored labels or have us print your labels in your own. Since two components are required to print this process, it is somewhat more complex and results in more waste.
It is crucial that printing with thermal transfer creates an imprint that remains on the image that is printed on the ribbon used. In sensitive areas where protection of data is a major factor should utilize label printing directly. We're happy to assist you in deciding which label and printing process is the best to your requirements.
Labels printed with direct thermal printers
Direct thermal printing implies that you don't need an ink ribbon because it is coated by a thermo-sensitive layer. The heat produced by the dots on the print head triggers an chemical reaction in the coating. The result is the image that prints.
Direct thermal printing can be more effective than thermal transfer printing and also costs less because no ribbons are required. However, the image that is printed is more delicate. A good example can be seen in the reception. Printing fades due to the consequence from UV light (light) and friction and heat. Direct thermal printing can only be used to print in one color (black).
Strategies: You can easily detect the difference by using scratch tests. Scratch the label with an object that is solid (such like a coin or pen) or your fingernail. If you notice an unreadable black line, that is the label has an Elastomeric coating (direct thermal printing).
