With the development of science and technology, printed materials are playing an increasingly important role in our lives. Thermal paper and three thermal paper as common printing materials, in the market attention. However, many people do not know the difference, and this article will explain the differences between the two in detail.
- Overview
Both thermal paper and tri-thermal paper are materials that print information on paper through thermal printing. However, there are clear differences.
- Working principle
Thermal paper is a kind of paper that is easily affected by heat. The working principle is that under the action of heating the print head, the tweezers cut the ink layer off, thus leaving a text or image on the paper. This printing method has the advantages of simple operation and fast printing speed, so it is widely used in many applications.
In contrast, the three thermal paper is a specially treated thermal paper. By coating the surface of the paper with waterproof, oil, stain and other materials, it enhances its ability to resist the erosion of external substances while ensuring the printing effect. In addition, the three heat-proof paper also has high heat resistance and light stability, which can avoid damage or change of the printed content due to high temperature or ultraviolet irradiation.
- Physical properties
Due to the special coating treatment of the three-proof thermal paper, it has excellent physical properties than ordinary thermal paper. The three heat-proof paper not only has the characteristics of waterproof, oil-proof and stain-proof, but also has good wear resistance and tear resistance. This makes it more suitable in some occasions that require frequent wiping or operation, such as making durable labels, access passes, etc.
On the other hand, ordinary thermal paper is susceptible to temperature, humidity, ultraviolet and other factors, resulting in printed content easy to disappear or discolor. Therefore, ordinary thermal paper has obvious disadvantages in terms of service life and anti-interference compared with three thermal paper.
- Use environment
Because the three heat-proof paper has the characteristics of waterproof and oil-proof, it is mainly used for printing labels, receipts, tickets and other printing occasions that need to be stored for a long time and are waterproof and oil-proof. For example, the price plate of the supermarket, the waybill of the express company, the key card of the parking lot, etc., need to use the three heat-sensitive paper.
In contrast, ordinary thermal paper is more suitable for some temporary printing needs, such as cashier receipts, restaurant ordering menus, etc. Because ordinary thermal paper does not have the characteristics of waterproof and oil-proof, it is easily affected in wet or high temperature environments, resulting in the disappearance or discoloration of the printed content.
