With the gradual enhancement of people's awareness of environmental protection, more and more consumers begin to choose to use environmental protection bags, and plastic woven bags have become a more popular choice for consumers. However, the problem of different color shades of plastic woven bags has also become a major difficulty restricting its development. This paper will analyze the causes and solutions of the problem from the following aspects.

Impact of 1. printing equipment and materials

The printing color of plastic woven bags is different, which is largely related to the quality of printing equipment and materials. If the quality of the printing equipment and materials used is low, it is difficult to ensure the quality and effect of printing. At the same time, the selection and use of printing equipment and materials also need to have the corresponding technical ability, only to master the printing technology and equipment suitable for their own production requirements, can achieve the consistency of printing color.

2. human improper operation

In the production process, the professional skills and operating experience of the operator will also directly affect the color of the plastic woven bag printing. If the technical level of the operator is not high enough, or the changes caused are not accurate enough, it may lead to different shades of printed colors. At the same time, the printing process also need to strictly control the temperature, humidity and other environmental factors, to avoid the impact of printing factors on the printing quality.

Unreasonable 3. printing design

In addition, the plastic woven bag printing color shades may also be due to unreasonable printing design. If the printing design pattern is complex, the color contrast is low, or the designer does not take into account the characteristics of materials and printing equipment when making the printing draft, it may lead to the problems such as the color of the printed matter is not bright enough, light, and the color difference is too large.

In view of the above problems, I think they can be solved from the following aspects:

1. Improve the quality of printing equipment and materials

In the choice of printing equipment and materials need to consider its quality, choose suitable for their own production requirements of printing equipment and materials. In addition, when using printing equipment and materials, it is also necessary to have the corresponding technical ability and experience to ensure the quality of printing.

2. Strengthen the training of operation skills and experience

By strengthening the training of operating skills and experience, improve the professional skills of operators, improve the ability to control the printing process, and avoid the decline in the quality of printed materials due to human factors.

3. Formulate a reasonable printing design plan

In the printing design, it is necessary to take into account the characteristics of specific materials and printing equipment, formulate a reasonable printing design plan, increase printing color, improve contrast, etc., in order to avoid the emergence of printing color shades and other problems.

To sum up, as a woven bag manufacturer, if you want to solve the problem of different printing colors, you first need to choose high-quality printing equipment and materials, and then strengthen the training of operating skills and experience, and give full play to the designer's design to develop a reasonable printing plan. Only by taking comprehensive measures can we solve the problem of different printing colors and improve the printing quality and market competitiveness of plastic woven bags.
