From a global perspective, especially in the European and American markets, gravure printing is mainly used in four major fields: publishing, packaging, textile and decorative.
First, the field of publishing and printing requires fast plate-making in this field, because the publishing roller used in the field of publishing and printing has a large format, and the large size can reach 4.8m, and the amount of information processed is large. Therefore, multi-channel (16 channels) is generally used. The engraving technique is used to engrave the plate cylinder.
Second, the packaging and printing field in the field of packaging roller is relatively small, but requires high quality plate making, especially for cigarette packets; the amount of information changes is large, and the requirements for fine text and color are high.
The main methods of plate making used in the packaging field are:
Screening gravure method;
An electric engraving method using offset color separation chips or digital files;
Laser plate making method using a sensitizer;
Laser plate making method using black primer;
Laser plate making using electroplated alloys.
Third, the application of gravure printing in the textile field in the textile field is mainly used for transfer printing on fabrics, mostly based on spot color reproduction, generally copying colors can reach as many as 6 colors. In plate making, the precision of plate making is not high, but the amount of ink is relatively large. Generally, the thick wire of 54~60lpc is used, and the plate making method is the same as that of packaging gravure printing.
4. The application of gravure printing in the field of decorative materials is mainly used for the printing of materials such as architectural decoration materials, wallpapers and flooring materials. The unit pattern is large, the spot color is printed, and the reproduction accuracy of the color is very high. It uses the same plate making method as in the field of packaging gravure printing.
