Thermal Paper (often supplied in roll form, and sometimes referred to as an audit roll) is a special fine paper that is coated with a material formulated to change color locally when exposed to heat. It is used in thermal printers, particularly in inexpensive devices such as adding machines, cash registers, and credit card terminals and small, lightweight portable printers.
Heat Activation: Thermal paper utilizes a heat activation process for printing. When heat is applied to the paper through the thermal printhead of a printer, the heat-sensitive coating reacts and changes color. This eliminates the need for ink or toner cartridges, making thermal printers more cost-effective and low-maintenance.
Instant Printing: One of the significant advantages of thermal paper is its ability to produce prints instantly. As soon as heat is applied, the paper reacts and creates the desired image or text. This makes thermal printing ideal for high-speed printing applications, such as retail receipts or transaction records.
Durability: Thermal paper is designed to be durable and long-lasting. It can resist fading, smudging, and water damage, ensuring that the prints remain legible and intact over time. This durability makes it suitable for various applications, including receipts, shipping labels, tickets, and healthcare records.
Sensitivity to External Factors: While thermal paper offers durability, it is important to note that it can be sensitive to certain external factors. Prolonged exposure to heat, direct sunlight, and certain chemicals or solvents can cause the prints to fade or become illegible. It is recommended to store thermal paper in a cool and dry environment to maintain its quality.
Overall, thermal paper offers instant printing, durability, customizability, and compatibility with thermal printers. Its roll format, environmental considerations, and versatile applications make it a popular choice for various printing needs.
