There are two main aspects of the production of cosmetic packaging materials: one is the coloring process, and the other is the printing process that will be introduced today. The coloring process is generally used for the processing of the bottle body, and the printing process is generally used for the processing of the LOGO.
The cosmetics printing process can generally be divided into five aspects: screen printing, hot stamping, water transfer printing, thermal transfer printing, and offset printing. Zhejiang Jinsheng New Materials Co., Ltd. introduces the characteristics of these five printing processes:
Silk screen: After printing, the effect has obvious unevenness, because it is a layer of ink.
The regular bottle (cylindrical type) of silk-screen printing can be printed at one time, and the other irregular one has a one-time cost. The color is also a one-time cost, which is divided into two types: self-drying ink and UV ink.
Hot stamping: It is a thin layer of paper stamped on it, so there is no bumpy feeling of silk screen printing.
Hot stamping is best not to directly on the two materials of PE and PP, you need to perform thermal transfer first and then hot stamping, or good hot stamping paper can also be directly hot stamped.
Water transfer printing: It is an irregular printing process carried out in water, the printed lines are inconsistent, and the price is more expensive.
Thermal transfer: Thermal transfer is mostly used for products with large quantity and complicated printing. It belongs to attach a layer of film on the surface and is expensive.
Offset printing: It is mostly used for aluminum-plastic hoses and all-plastic hoses. If the offset printing is a colored hose, you must use silk screen printing. The offset printing will show the background color and sometimes attach a layer of bright film or sub-surface on the surface of the hose. membrane.
