The handwriting generated by fax or printing on thermal paper is unstable and will fade naturally. The reason is that the color reaction of thermal paper is reversible, the colored product will decompose by itself in different degrees, and the color of the writing will fade gradually and gradually until the writing completely disappears in the white paper. Therefore, it will accelerate the decomposition of color products and accelerate the fading of text and text under the action of external conditions such as a long time for placing, long time for illumination, long time for heating and under the action of external conditions such as high ambient temperature, moist environment and contact adhesive paper. Of course, the speed of fading also relates to the thermal sensitive materials of thermal paper.
