Thermal paperis a material printed by thermal printing technology, which is suitable for occasions where a large number of bills or documents need to be printed. It has the advantages of fast, clear and convenient, and is widely used in medical, laboratory, logistics and other fields. The working principle and application fields of thermal paper will be introduced in detail below.
1. Working principle
Thermal paper will be coated with a layer of thermal coating, by heating the print head in contact with the paper surface, so that the thermal dye reacts with the color generator to form patterns or characters. Among them, the thermal dye is a substance that can be dissolved at high temperature, and the color generating agent is a substance that can be reduced by the thermal dye. When the print head is heated, the thermal dye will react with the color generator to form a corresponding pattern or text on the paper. This method has the advantages of fast, clear and convenient, and is especially suitable for occasions where a large number of bills or documents need to be printed.
2. Field of application
Thermal paper is widely used in medical, laboratory, logistics and other industries, and its main application areas include:
(1) Medical industry: Thermal paper is used to print various laboratory tests, inspection reports, prescriptions and other documents, which can improve work efficiency and accuracy.
(2) Laboratory industry: Thermal paper is suitable for printing various laboratory reports, sampling labels, reagent labels and other identification items, making the experimental operation more convenient.
(3) Logistics industry: Thermal paper is a common express delivery material, which can print clear barcodes and address information, which is convenient for logistics centers to classify and manage.
(4) Catering industry: thermal paper is also used to print restaurant cashier receipts, which has fast printing speed and high definition, which can improve service efficiency.
(5) Financial industry: Thermal paper is suitable for printing various documents such as bills, vouchers and invoices, which can improve production efficiency and accuracy.
In short, thermal paper has been widely used in medical, laboratory, logistics and other fields due to its fast, clear and convenient characteristics, providing efficient solutions for various industries.
