What is the difference between thermal label and thermal transfer label printer?
2021-11-05 14:05

       With the development trend of economy and society, labels are widely used in products, which promotes the rapid development of label printing industry, and labels bring a lot of convenience to our lives. However, each industry has different requirements for labels. Some careful friends will find that some labels wear out quickly, and the handwriting will be blurred after a period of time. Some labels are particularly strong, and the handwriting is still clear after several years. Why is this?

       Different labels are printed by different label printers. Generally, label printers have two printing methods: thermal label printing and thermal transfer label technology. Actually, it has something to do with the way labels are printed and consumables. Today, let's introduce the differences between thermal and thermal transfer label printers.

01 different technical principles.
       Heat transfer is the process of transferring the carbon powder of a specially made ribbon to the printing material at high temperature by heat transfer technology, and finally forming a pattern on the label material.
      Thermal printing is a precise electric heating device, which uses thermal sheets. Each thermal sheet is lined with many tiny electric hot spots. When the electric hot spots are hot, the corresponding position of the thermal paper pressed on the thermal sheet will turn black. When the paper roll is dragged by the motor, the heating spot will change according to the change of printing data, and finally, characters or patterns will be formed on the label.

02 consumables are different.
       Thermal transfer ribbon or carbon ribbon is required, but thermal sensitivity is not required.
       The thermal transfer label consumables can be labels such as PET, PVC, reflective film, aluminum alloy and composite PET material. However, thermal printing can only use special thermal paper, which is coated with a coating that changes color through chemical reaction when heated, so as to realize thermal printing.

03 The shelf life of labels is different.

        Thermal transfer labels can be stored for a long time, usually about 10 years, depending on the quality of label paper and carbon tape. The storage time of thermally printed labels is short, generally half a year. The specific storage time is closely related to the storage environment, light, temperature and climate of the place of use.

04 labels are applied in different industries.

         Printing self-adhesive label: mainly used for marking the price, management and packaging of commodities and other information labels in retail, new retail and medical application fields.
        Heat transfer label:

1.PE (polyethylene) adhesive labels and PP (polypropylene) adhesive labels.
       The fabrics are transparent, bright milky white and matte milky white.
        Key product labels with waterproof, oil-proof, UV-resistant and chemical properties are used as information labels for high-end goods and environmental protection products.
2. Polyester PET self-adhesive label.
       The fabrics are transparent, bright gold, bright silver, sub-gold, sub-silver, milky white and matte milky white.
       Key product labels with water-proof, oil-proof, UV-resistant and chemical properties are especially suitable for information labels such as tableware, household appliances and fruits. After peeling the self-adhesive sticker, the product has no trace.
3.PVC plastic self-adhesive label.
         The fabrics are transparent, bright milky white and matte milky white.
         Key product labels with waterproof, oil-proof, UV-resistant and chemical properties are suitable for manufacturing, automobile industry, textile industry, telecommunication industry, food industry, electronic industry, chemical industry, pharmaceutical industry, pharmaceutical industry, public utilities, retail distribution industry, transportation logistics, government agencies and other enterprises.
