What are the requirements for the design draft for custom plastic packaging bags？

When we customize plastic packaging bags, we usually invite advertising companies to design, beautiful design schemes, and superb printing technology, the two can work together to produce an excellent plastic packaging bag. Some plastic packaging bag manufacturers also provide design services, but they are not professional advertising companies after all. design. However, the design draft of gravure color printing has some special requirements, specifically the following:

1. Format.

Usually, the design draft provided by the plastic packaging bag manufacturer to the plate-making factory needs to be in PS format, but due to the difference in color separation and plate-making methods, some plate-making factories also need AI format files. The picture format must not be used, and the CD format may not meet the needs of the plate maker.

Second, the resolution.

The source file resolution required by the plate making factory is generally 300. If the bag is relatively small, the resolution needs to be 400.

Third, the color mode.

The source files of the plate factory require CMYK mode, and the files in RGB mode cannot be used for gravure printing.

Fourth, the number of colors.

Since most of the color printing machines used by printing factories have only 9 colors, your design manuscript source file colors cannot exceed 9 colors. There are also some large color printing factories with 12 color printing machines, but it is relatively rare. In order to have more choices for you, It is recommended that your design draft has no more than 9 colors. The colors mentioned in gravure printing are different in meaning from the colors we see with the naked eye. Specifically, you can ask the designer to help you separate the colors.
