Description
Thermal paper is a type of paper that is coated with a special
heat-sensitive material. This coating reacts to heat by changing
color, which is used to create images and text without the need for
ink. Here's a brief overview:
1. **Composition**: Thermal paper typically has a multi-layer
coating. The top layer is sensitive to heat and contains dyes or
pigments. Underneath this is a layer of a base coat and sometimes a
protective layer.
2. **How It Works**: When heat is applied, such as by a thermal
printer head, the coating changes color, producing the desired text
or image. This is why thermal paper is commonly used in thermal
printers.
3. **Applications**: It is widely used in applications like receipt
printers (e.g., point-of-sale systems), label printers, and for
printing tickets. Its also used for medical and industrial purposes
where quick and efficient printing is needed.
4. **Advantages**: Thermal paper is quick and silent in operation,
doesn't require ink or ribbons, and is generally cost-effective for
high-volume printing.
5. **Considerations**: Thermal paper can be sensitive to heat and
light, which may cause the printed content to fade over time. Its
important to store thermal paper in cool, dry conditions to
preserve the print quality.
Thermal paper is valued for its efficiency and ease of use in
various printing applications.
