How to preprocess the hang tag copperplate paper before printing?

Pre processing the hang tag copperplate paper before printing is a very important step, which helps to improve the printing quality and effect. The following are the detailed steps for preprocessing the hanging tag copperplate paper:

1、 Surface cleaning

Firstly, it is necessary to clean the surface of the copperplate paper. Gently wipe the surface of the paper with a clean soft cloth or dust-free paper to remove impurities such as dust and oil stains. Ensure that the surface of the paper is clean and flat, which is conducive to the uniform adhesion of ink.

2、 Surface polishing

The surface of copperplate paper may have slight unevenness, which can affect the adhesion of ink and printing effect. Therefore, polishing tools such as sandpaper or grinding wheels can be used to lightly polish the surface of the paper to make it smoother. When polishing, the force should be controlled to avoid excessive polishing causing damage to the surface of the paper.

3、 Coating ink absorption layer

To improve the adhesion and drying speed of ink on copperplate paper, a layer of ink absorbing layer can be coated on the surface of the paper. This absorption layer can be a coating composed of specific chemicals that can enhance the paper's ability to absorb ink. When coating, it should be uniform and appropriate to avoid the coating being too thick or too thin, which may affect the printing effect.

4、 Adjust the humidity of the paper

The humidity of copperplate paper also has a certain impact on the printing effect. If the humidity of the paper is too high, it will cause uneven ink diffusion; If the humidity is too low, it may cause paper deformation or poor ink adhesion. Therefore, it is necessary to adjust the humidity of the paper before printing to maintain it within an appropriate range. Paper humidity can be adjusted through humidification or drying methods.

5、 Check the quality of the paper

After the preprocessing is completed, it is necessary to check the quality of the copperplate paper. Check whether the surface of the paper is flat, free of damage, stains, etc. At the same time, it is necessary to check whether the specifications and dimensions of the paper meet the printing requirements. Ensuring good paper quality is beneficial for improving printing quality and efficiency.

In summary, preprocessing the hanging tag copperplate paper is an important step in improving printing quality and effectiveness. By taking measures such as surface cleaning, surface polishing, coating ink absorption layer, adjusting paper humidity, and checking paper quality, it is possible to ensure that the paper exhibits good printability during the printing process.
