What problems may occur during the printing process of PET matte silver label paper?

The possible problems that may occur during the printing process of PET matte silver label paper mainly include the following aspects:

1、 Unclear printing or discontinuous lines

This may be due to excessive printing speed or insufficient printing density. To improve this issue, you can try adjusting the speed and density settings of the printer. For example, in the printer's preference settings, you can reduce the printing speed and increase the printing density appropriately to ensure clear printing content and continuous lines. At the same time, ensure the use of resin based carbon tape that matches the printer and label paper to ensure optimal printing results.

2、 Carbon ribbon fracture

Carbon ribbon breakage is one of the common problems in the printing process of PET matte silver label paper. This may be due to poor quality of the carbon ribbon, insufficient width, or high printing density. To avoid breakage of the carbon ribbon, it is recommended to choose a reliable quality carbon ribbon and ensure that its width matches the width of the label paper. In addition, when adjusting the printing density, it should be avoided to set it too high, so as not to increase the burden on the carbon ribbon and cause breakage.

3、 Ink adhesion is weak or easy to erase

If the ink layer on the surface of PET matte silver label paper dries slowly or is easily erased, it may be due to improper ink type, insufficient surface tension of the printing material, or low power of the drying device. To solve this problem, the following measures can be taken:

Select specialized ink and matching additives that match the printing material to ensure that the ink can firmly adhere to the surface of the label paper.

Improve the surface tension of the printing material to achieve the minimum value required for ink adhesion. This can be achieved through methods such as corona treatment or the use of transparent solvent based ink.

Increase the drying or curing power, or reduce the machine operating speed to prolong the drying time of ink and improve its adhesion strength.

4、 Static electricity problem

When printing PET matte silver label paper, static electricity may cause equipment operating system malfunctions or uneven film material winding. To reduce the impact of static electricity, humidifiers can be added to the workshop to increase relative humidity and eliminate the influence of static electricity on equipment and materials.

5、 Other precautions

Before using PET matte silver label paper for printing, it is necessary to ensure that the printer and carbon ribbon equipment are in good working condition to avoid printing problems caused by equipment failure.

During the printing process, it is necessary to regularly check the printing quality and effect, and promptly identify and solve problems.

When storing PET matte silver label paper, it should be placed in a dry and cool environment to avoid moisture or high temperature that may cause the label paper to deteriorate or be damaged.

In summary, the possible problems that may occur during the printing process of PET matte silver label paper include unclear printing, carbon tape breakage, weak or easily erasable ink adhesion, and static electricity issues. To address these issues, a series of measures need to be taken to ensure print quality and effectiveness.
