How to calculate the plate making fee for plastic bags？

At present, the composite packaging bag is generally a gravure printing process, so plate making is required. When many customers customized plastic packaging bags for the first time, they did not understand why they had to make plates, and they also had a lot of questions about the plate fee.

First of all, the design draft of the packaging bag designed by the design company should be handed over to the designer of the plate making factory for reprocessing, adjusting the resolution and file format, separating the colors, splicing different sides of the design draft, etc. Finally, it is necessary to Imposition.

After the color is determined, the diameter and width of the plate roller are determined according to the size of the bag, the equipment of the printing plant, and the width of the raw material film, and the plate fee can be calculated according to the following formula:

Plate fee = circumference of plate roll * width of plate roll * unit price per square centimeter * number of colors

The unit price per square centimeter is calculated according to the quotation of the plate-making factory, which is generally 0.12-0.15 yuan. The cost of plate-making varies from manufacturer to manufacturer.

For the same packaging bag, the diameter and width of each version are the same. No matter what version, the printed packaging bag is the same. You can communicate with the packaging bag manufacturer to choose the most favorable plate-making method.
