What problems should be paid attention to when printing thermal label paper

The printing of thermal label paper is carried out under the heat of the print head. During the printing process, the heat-sensitive parts of the thermal paper will turn black under the heat of the print head, while the non-heat-sensitive parts will not change color. In this way, the heat-sensitive parts will become text or barcodes, so as to achieve the desired effect. .

It should be noted that the thermal label paper will blacken the heat-sensitive parts through heat and chemical action, so at room temperature, the writing on the thermal paper will become a little unstable, and the writing will fade away, making the printed content difficult to read. . Therefore, the content printed on thermal label paper is generally not suitable for long-term storage. Nowadays, good thermal printing paper can be stored for 5 years at room temperature and away from direct sunlight after printing, and now there are long-lasting thermal papers that can be stored for 10 years, but if the formula of the thermal coating is unreasonable, it may only be It can be kept for several months.

For thermal paper, pay attention to the uniformity of the printing, because if it is uneven, some places will be dark in color, and some places will be light in color, and the printing quality will be significantly reduced. If the chemical formula of the thermal coating is unreasonable, it will As a result, the storage time of printing paper becomes very short. The protective coating is also critical to the storage time after printing. It can absorb part of the light that causes the chemical reaction of the thermal coating, slow down the deterioration of the printing paper, and protect the thermal components of the printer from damage.
