What is a Thermal Paper?
Thermal paper is a special paper type that is coated with a material formulated to change colour when exposed to heat. It is used in thermal printers and particularly in inexpensive or lightweight devices such as adding machines, cash registers, and credit card terminals. Thermal paper is used because it is relatively inexpensive, it produces clear images, and it does not require any special equipment such as ribbons or ink cartridges for printing.
The thermal paper printing process begins with the thermal paper being exposed to a heat source. The heat source is typically a thermal printhead that is activated by an electrical current. When the thermal printhead is heated up, it causes the coating on the thermal paper to change colour. This colour change is what creates the image on the paper.
The thermal paper coating is made from a combination of materials, including colour pigments, chemical developers, waxes, and resins. The colour pigments are usually made up of dyes or pigments that are sensitive to heat and will change colour when heated. The chemical developers are usually substances that will cause the colour pigments to react to the heat and change colour. The waxes and resins are used to help provide a protective layer to the paper and to provide a glossy finish.
Thermal paper is used in a wide variety of applications, ranging from printing receipts in retail stores to printing labels and other documents in industrial settings. Thermal paper is relatively inexpensive and can be used in a wide variety of applications, it is an ideal choice for businesses that are looking for a cost-effective way to print documents. The main benefit of thermal paper is that it does not require any special equipment for printing and can be used in a wide variety of applications. It also produces clear images and can be used to print documents quickly and easily. Although thermal paper does not require any special equipment for printing, it does need to be stored properly to ensure that it retains its quality. Thermal paper should always be stored in a cool, dry place and should never be exposed to direct sunlight or extreme temperatures. It should also be kept away from any heat sources and should be stored in an airtight container.
