Printing Process​

Nowadays, the material mugs used are processed into color changing mugs with mainly one of these three methods: 1. Direct printing; 2. Water transfer printing; 3. Heat transfer printing. These three technologies are used for processing.

  1. Direct printing

Direct printing refers to printing directly on mugs with a roll printing machine, which is somewhat difficult. Rolling printing machines in ordinary factories can only print one to three colors. If there is a high requirement for set positions and many colors, there is nothing could be done. However, powerful factories can overprint as many as 20 colors without blocking. This technology only applies to small batch production and with it, the efficiency is very low. Besides, with this technology, only color blocks can be printed and photo effects are difficult to print.

  1. Water transfer printing

With a printing machine, the water transfer printing paper with rich colors can be printed, and there will be a mass production. However, the environmental requirements are relatively high, requiring a constant temperature and humidity in the printing environment to ensure printing accuracy. The printed water transfer printing paper is placed in water, and its pattern is separated from the paper, and then the pattern is pasted onto a mug to bake the finished product. The following Christmas color changing mug undergoes this process.

2.Heat transfer printing

The heat transfer printing process is basically the same as that of water transfer printing, and the printed heat transfer paper is heated and pressed by a machine to be pasted on the mug body. When the color-changing mug is produced with the water transfer printing method, the pattern is transferred manually, while when the color-changing mug is produced with the heat transfer printing, the pattern is processed automatically by the machine. Thus, it can be seen that a modern color-changing mug factory with a color change pigment production line, a full-automatic printing production line and a full-automatic heat transfer decal production line has the strongest competitiveness.
