Is the handwriting on the three proof thermal paper prone to fading?

The handwriting on three proof thermal paper is less likely to fade compared to ordinary thermal paper. This is mainly due to the special production process and material selection of the three proof thermal paper.

Firstly, the three proof thermal paper adopts a special thermal coating process, which makes the surface of the paper smoother, easier to print, and the printed handwriting clear. More importantly, this coating also has certain protective properties, which can resist the erosion of external environment on handwriting.

Secondly, special colorants and stabilizers may be added during the production process of the three proof thermal paper, which can enhance the stability of the color reaction and reduce the possibility of handwriting fading. In addition, the three proof thermal paper also has waterproof, oil proof, and alcohol proof properties, which further enhance its ability to resist fading.

However, despite the aforementioned advantages of three proof thermal paper, its handwriting may still fade under certain extreme conditions, such as prolonged exposure to strong sunlight, high temperature and humidity environments, or exposure to certain strong oxidants. Therefore, when using and storing three proof thermal paper, it is still necessary to avoid the influence of these adverse conditions.

Overall, the handwriting on three proof thermal paper is less likely to fade compared to ordinary thermal paper, but it is still necessary to pay attention to the use and storage conditions to avoid handwriting fading. If the handwriting fades, you can try using methods such as constant temperature heating to restore it, but the effect may vary depending on factors such as paper quality and fading degree.
