The difference between thermal paper and regular paper

Thermal paper and regular paper have several key differences in terms of composition, printing method, and use. Here’s a breakdown of the main distinctions:

1. Composition and Coating

Thermal Paper:Thermal paper is coated with a special heat-sensitive chemical layer, typically made of leuco dye and a developer (often an acid). When exposed to heat, this chemical coating reacts to produce a visible image or text.

The coating is designed to change color (usually black or dark blue) when it comes into contact with the heat from a thermal printer’s printhead.

Regular Paper:Regular paper is made from wood pulp or other fibers and usually has a smooth, uncoated surface. It does not contain any heat-sensitive chemicals, so it relies on ink or toner to produce printed images or text.

2. Printing Method

Thermal Paper:No ink or toner is used in thermal printing. Instead, a thermal printhead applies heat directly to the paper. The heated areas of the paper change color, forming the printed image or text.

Regular Paper:Regular paper is printed using traditional printing methods, such as inkjet, laser, or offset printing, where ink or toner is applied to the paper to create text or images.

3. Durability of the Print

Thermal Paper:Thermal prints can fade over time, especially when exposed to heat, sunlight, or chemicals. The print is typically not as durable as prints on regular paper and may deteriorate quickly if improperly stored. Some types of thermal paper are more durable and fade-resistant, but generally, it is not ideal for long-term storage unless protected from environmental factors.

Regular Paper:Prints on regular paper tend to be more durable when stored in appropriate conditions. Inkjet or laser prints can last for many years without significant fading, especially with high-quality ink or toner and acid-free paper.

4. Speed and Efficiency

Thermal Paper:Thermal printers are much faster than traditional ink-based printers because the printing process only involves applying heat to the paper, without the need for ink or toner.

The printing process is quiet, efficient, and doesn’t require additional consumables like ink cartridges or ribbons.

Regular Paper:Regular printers (e.g., inkjet or laser printers) tend to be slower because they need to spray or fuse ink/toner onto the paper. These printers are typically noisier and require more maintenance, such as replacing ink cartridges or toner.
