We can print text on paper through thermal transfer technology. Of course, there are many ways to use thermal. It is fast, convenient and affordable. How long can the handwriting on thermal transfer paper be stored?
The handwriting on the thermal transfer paper can be stored for about 5 years. If it is too long, it may be unclear. A good printed paper can be stored (under the premise of preventing sunlight exposure at room temperature) for 5 years after printing, and there is also a high-efficiency thermistor paper that can be stored for 10 years, but if the secret recipe of thermistor coating is unscientific, it is very It may only be kept for several months. The maintenance of the coating is also very important for the storage time after printing. It can digest and absorb part of the light source that causes the chemical changes caused by the thermistor coating, and alleviate the mildew of the printed paper.
Thermal printing paper is generally divided into three layers, the bottom layer is the paper base, the second layer is the thermistor coating, and the third layer is the protective layer. The key to its quality is the thermistor coating or protective layer. If the coating of the thermistor paper is uneven, it will cause some areas to be dark in color and some areas to be light, and the printing effect will be significantly reduced. The storage time is getting shorter and shorter.
How does thermistor paper have a shelf life? Since the thermistor paper is a unique self-adhesive sticker, its basic working principle is: enter the printed information into the cash register, arouse the temperature of the printer nozzle, induce a chemical reaction in the discolored layer of the thermistor paper, and then show a clear text and images.
Therefore, the original voucher printed on the thermistor paper cannot be permanently saved, and the writing on it will become lighter with time. However, the speed of fading is closely related to the quality of the thermistor marking paper itself, its solution and storage methods. Generally, the thermistor marking paper will determine the corresponding storage time due to the material structure and storage working temperature. If it is exposed to the sun and the temperature is higher than 30 °C, it will only be stored for about ten days. If the common marking paper is in a cool place, It's okay to keep it for a year or so.
The long-term preservation of thermal printing paper is closely related to the quality of its own products. The quality of the quality determines the quality of the printed data information, and the long-term preservation of the data and information, and even under the accumulation of time. It will affect the life of the copier. Generally, the shelf life we see on the label printer packaging is more than 30 years, which is also guaranteed by very good thermal printing paper. The shelf life of poor-quality thermal printing paper is only about half a year, and the shelf life of thermal printing paper with better relative quality is four or five years.
