The mug adopts thermal transfer technology, and it is necessary to spray a layer of transparent resin decal paper with certain special requirements on the surface of ceramic crafts. Generally, special thermal sublimation ink is printed on inkjet or special paper by a printer, heated at a certain pressure and temperature, and then transferred to coated ceramic glass.
The color-changing mug is made of temperature-sensitive color-changing ink. Because its color-changing process is reversible, it is also called "reversible temperature colorless ink". When the temperature rises, the bottom layer is displayed. After hot water is poured into the drinking cup, the heat-sensitive liquid in the interlayer cavity will change color and escape into the graphic channel of the inner cup, so that the cup wall presents artistic patterns, which makes people get aesthetic feeling and artistic enjoyment.

Full-color cup technology breakthrough, price breakthrough Full-color cup is a legend in the color-changing cup (full-color cup is a cup whose whole cup body will change color except for the cup handle). It was first developed by a British company, and applied for technical patents in European and American markets. In 2004, Meikeda, an American company headquartered in Beijing, introduced it to China market.
It is reported that the company pays a large amount of patent fees to British companies in European and American markets every year. The technology of all-color products was very mature at that time. Because the production of high-gloss full-color-changing cups has high technical requirements for workers and imported raw materials, the price is higher. Although there were not a few factories that could produce full-color cups at that time, they produced very good high-gloss full-color cups with a certain product qualification rate.
