At present, the material cups are processed into color-changing cups by one of three methods: 1. Direct printing; 2. Water transfer printing; 3. Thermal transfer printing. These three processes are used for processing. 1. Direct printing: refers to printing directly on cups with a roller printer. This technology is technically difficult. Generally, 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 2 colors without leaving the position. This technology is only suitable for small batch production, and its efficiency is very low. It can only print color blocks, and the effect of printing photos is very difficult. 2. Water transfer printing: firstly, the printing machine is used to print on water transfer printing paper, so that rich colors can be printed. Similarly, it can be produced in large quantities in Christmas color-changing cups
. However, the requirements for the environment are relatively high, and the printing accuracy can be guaranteed only by the constant temperature and humidity of the printing environment. Put the printed water transfer printing in water, separate the pattern from the paper, and paste the pattern on the cup to bake the finished product. The following Christmas color-changing cups belong to this process: 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 produces color-changing cups, all the patterns are transferred manually by people, while thermal transfer is handled automatically by machines, so a modern color-changing cup factory, Having a production line of color-changing pigments, automatic printing production line and automatic thermal transfer decal production line is the strongest manifestation of competitive strength

The new colored glaze color-changing cup is similar to a local color-changing cup, and the color-changing coating is only applied to the printing position. There is no obvious trace. In the past products, including all the products on the market, there are colored glazed cups, the discoloration effect is not obvious, the edges are white, and you will feel obvious when you touch them with your hands. In terms of price, the traditional production technology is 3% higher than the current new technology, and the current price is only 12% different from the price of ordinary color-changing cups. Red glazed color-changing cup (colors are black, blue, yellow, green ...)

This is another style ——————————————————————— The technology of full color-changing cup has broken through, and the price has changed completely
. It was first developed by a British company and applied for technology patents in European and American markets. In China market, it was introduced by Meikeda, a Beijing-based American company, in 24. It is reported that this company has to pay British companies a lot of royalties in European and American markets every year. At that time, the technology of full-color-changing 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 the factories that can produce full-color-changing cups no longer have feather scales, it is necessary to have expensive professional equipment and skilled production workers to make good high-gloss full-color-changing cups and a certain product qualification rate. In 26, the raw materials of high-gloss full color-changing cup painted once in China were successfully developed by Zhejiang Jiangkou Coating Chemical Plant and Zhejiang University, which played a key role in reducing the production cost of color-changing cups. Besides domestic products, the raw materials of color-changing cups are also made in Japan and Germany. There is a big price gap between different manufacturers in the domestic full-color cup market, which is caused by the inconsistent factory qualification standards of full-color cups of various manufacturers and the different production 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 body is covered with pimples, and the price of non-flat defective products will be cheap. Other domestic manufacturers basically refer to hearsay or self-exploration for the production of this product. In 24, there were factories in China that could produce and export stably.
