At present, the material cups used are processed into color-changing cups by one of three methods: 1, directly printed; 2. Water transfer printing; 3. Thermal transfer printing. These three processes are used for processing. 1, direct printing: refers to printing directly on a cup with a roller printer. This technology is technically difficult. Ordinary factories can only print one or three colors. If there is a high demand for registration, there is nothing they can do. However, powerful factories can overprint as many as 20 colors without leaving their positions. This technology is only suitable for small batch production and its efficiency is very low. Only color blocks can be printed, and the effect of printing photos is very difficult. 2. Water transfer printing: First, it is printed on the water transfer printing paper with a printing machine, which can print rich colors and a large number of Christmas color changing cups.
Production, but the environmental requirements are relatively high, and the printing environment is required to be constant temperature and humidity, so as to ensure the printing accuracy. The printed water is transferred to the water, the pattern is separated from the paper, and the pattern is transferred to the cup to bake the finished product. The following Christmas color changing cups belong to this technology: thermal transfer color changing cups.
3. Thermal transfer: basically the same as the printing process of water transfer printing, the printed thermal transfer paper is transferred to the cup body by machine heating and pressure. When water transfer printing is used to produce color-changing cups, all patterns are transferred manually, while thermal transfer printing is automatically processed by machines. Therefore, the modern color-changing cup factory with color-changing pigment production line, automatic printing production line and automatic thermal transfer decal paper production line is the strongest embodiment of competitive strength.

The new colored glass cup is similar to the local one. The color-changing coating only treats the printing position, that is, the non-printing area is polished, so the cost is lower, the production speed is faster, and the edge of the product has no white background, no sawtooth and no obvious trace. In the past products, including all the products on the market, the color change effect of the glass cup was not obvious, and the edge was white, so it would be obvious when touched by hand. In terms of price, the traditional production technology is 30% higher than the current new technology, but today's price is only 12% lower than that of the ordinary color-changing cup. Red glaze color changing cup (colors are black, blue, yellow, green ...)

Breakthrough of full color-changing cup technology, price breakthrough of color-changing cup
Total color-changing cup is a legend in color-changing cup (total color-changing cup means that the whole cup body will change color except the handle does not change color). It was first developed by a British company and applied for technical patents in European and American markets. In China market, it was introduced by Meikeda, a Beijing-based American company, in 2004. It is reported that the company pays a large amount of royalties to British companies in the European and American markets every year. At that time, the technology of all-color products was very mature. Because the production of high-gloss full-color-changing cups has high technical requirements for workers, and the raw materials are imported, the price is higher. Although there is no feather scale in the factory that can produce full color-changing cups now, expensive professional equipment, skilled production workers and a certain product qualification rate are needed to make good high-gloss full color-changing cups. In 2006, Zhejiang Jiangkou Paint Chemical Plant and Zhejiang University cooperated to successfully develop the raw materials of high-gloss color-changing cups that were painted once in China, which played a key role in reducing the production cost of color-changing cups. In addition to domestic products, the raw materials of color-changing cups are also from Japan and Germany. There is a big price gap between different manufacturers in the domestic full-color cup market, which is caused by different factory qualification standards of full-color cups and different raw material costs. Generally speaking, the production process of matt full-color cups is relatively simple and the cost is low, so the price is cheap. Due to the limited technical level of technicians, the surface of the cup is covered with bumps, and the uneven defective products will be cheaper. Other domestic manufacturers are basically referring to hearsay or groping for this product. In 2004, there were factories in China that could produce and export stably.
