Thermal label paper does have a tendency to fade or blur, which is mainly due to its special material and printing principle. The following is a detailed analysis of the reasons why thermal label paper is easy to fade or blur:
First, thermal paper characteristics
Reversibility of color reaction: The color reaction of thermal paper is reversible, that is, the colored products on the printed writing or image will decompose themselves over time, causing the color to gradually become lighter or even disappear completely. This characteristic makes the writing or image on the thermal label paper easy to fade after being stored for a long time.
Sensitive to the environment: thermal paper is more sensitive to environmental temperature, humidity, light and other conditions. Under high temperature, high humidity, strong light and other environments, the fading speed of the writing or image on the thermal paper will be accelerated.
Second, printing and storage conditions
Print quality: Print temperature, speed, concentration and other factors will affect the print quality of thermal paper. If the printing temperature is not enough, the speed is too fast, or the concentration is set improperly, it may cause the printed text or image to be unclear or easy to fade.
Storage method: Thermal label paper should avoid long-term exposure to sunlight or damp environment during storage, so as not to accelerate fading. At the same time, contact with chemicals should be avoided, so as not to cause chemical reactions to blur or disappear.
Three, paper quality
Paper and coating: Thae paper and coating quality of thermal label paper directly affects its durability and printing effect. Poor quality thermal paper may cause the writing to fade or blur easily due to reasons such as not durable enough paper or uneven coating.
Additives: Somae inexpensive thermal paper may have added too much additives such as phosphors, which can improve the whiteness of the paper, but also reduce its durability and print quality.
Iv. Application scenarios
Outdoor use: In the outdoor environment, due to factors such as strong light, large temperature difference, and humidity changes, the writing or image on the thermal label paper is more likely to fade or blur. Therefore, when using thermal label paper outdoors, special attention needs to be paid to its storage conditions and service life.
Special environment: In the case of long-term storage or use in harsh environments such as high humidity and high temperature, it is recommended to choose better quality and more durable thermal label paper or other types of label paper.
In summary, thermal label paper is prone to fading or blurring due to factors such as its characteristics and use environment. In order to extend its service life and maintain print quality, it is necessary to select high-quality thermal label paper, pay attention to printing and storage conditions, and avoid use in harsh environments. At the same time, other types of label paper can also be considered to meet specific needs.
