2024-04-22
The material used for the cup is processed into a color changing cup, basically using one of three methods: 1, direct printing; 2, water transfer; 3, thermal transfer. These three processes to process.
1. Direct printing: refers to printing directly on the cup with a roller printing machine. This technology is technically difficult. Generally, factories can only print one to three colors. If they encounter high requirements for setting positions, there is nothing they can do with many colors. However, powerful factories can overprint up to 20 colors without leaving positions. This technology is only suitable for small batch production and has very low efficiency. Can only print color blocks, printing photo effect is very difficult.
2. Water transfer printing: it is printed on the water transfer paper with a printing machine, so that rich colors can be printed, and it can also be printed in large quantities.
Production, but the environmental requirements are relatively high, requiring the printing environment to be constant temperature and humidity, in order to ensure the printing accuracy, the printed water transfer paper is placed in 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 change cup belongs to this kind of craft.
3. Thermal transfer printing: The printing process is basically the same as that of water transfer printing. The printed thermal transfer paper is heated and pressurized by the machine and transferred to the cup body. When water transfer printing produces color-changing cups, all the patterns are manually operated by people, while thermal transfer printing depends on the machine.
Automatic processing, so a modern color-changing cup factory, with color-changing pigment production line, automatic printing production line and automatic thermal transfer decal production line, is the strongest embodiment of competitive strength.
