Problems solved by technology

[0002] Marker inks on the market are divided into water-based and oil-based. Marks written or made with water-based inks fade when exposed to water and can be easily wiped off with hands or cloth; , ethanol, ethyl acetate and other organic reagents are also easy to fade and erase when in contact. In special occasions, production accidents are prone to occur because the logo is dissolved and disappears
