About the principle of microprinter thermal paper production is the application of particulate powder on plain paper base, the composition is leuco dye phenols or other acidic substances, separated by a film, in the heating conditions, the film melts, the powder mixes from the color reaction The color writing on the thermal paper is unstable and fading, resulting in indecipherable document contents. When the thermal paper is placed in an environment of 70°C or higher, the heat-sensitive coating begins to change color.
Thermal papers for micro printers are generally divided into three layers. The bottom layer is paper-based, the second layer is a heat-sensitive coating, and the third layer is a protective layer. It mainly affects the printing and preservation quality of micro-printers by heat-sensitive coatings or The protective layer.
Now there are longer-lasting thermal papers that can be stored for 10 years, but if the formula of the heat-sensitive coating is not reasonable, it may only be kept for several months. The protective coating is also critical for the preservation time after printing. It can absorb part of it. The light that causes the heat-sensitive coating to chemically react.
Slow down the deterioration of printing paper, and can protect the thermal elements of the micro printer from damage, but if the protective coating is not uniform, not only will the protection of the heat-sensitive coating be greatly reduced, even a protective coating will appear during printing. The fine particles fall off, rubbing the thermal elements of the printer, causing damage to the printed thermal elements.
If the thermal paper coating is not uniform, it will cause the micro-printer to print in some places where the color is dark, some places are light in color, and the print quality is obviously reduced. If the chemical formula of the heat-sensitive coating is unreasonable, the printing paper will be saved. The time becomes very short, good paper can be stored at room temperature for 5 years after printing.
