How to solve the problem of PET matte silver label paper during the printing process?

Here are some specific solutions to the possible problems that may occur during the printing process of PET matte silver label paper:

1、 Unclear printing or discontinuous lines

Adjust printing speed and density:

In the printer preferences or control panel, reduce the printing speed and increase the printing density appropriately to improve the printing effect. The recommended printing speed is usually between 76.20mm/s and 78105mm/s, with a depth setting of around 815 or 10. The specific values need to be adjusted according to the printer model and actual situation.

Be careful to avoid slow speed or excessive depth, as it may cause the carbon ribbon to burn out or other problems.

Check and replace the carbon ribbon:

Ensure that the carbon tape used matches the printer and label paper, especially selecting resin based carbon tape suitable for PET matte silver label paper.

If the quality of the carbon ribbon is poor or approaching its service life, replace it with a new one in a timely manner.

2、 Carbon ribbon fracture

Adjust printer temperature and speed:

Reduce the temperature and speed of the printer to minimize the burden and wear on the ribbon.

If the problem still persists after adjustment, it may be necessary to further inspect the mechanical components of the printer or contact professional technicians for repair.

Check the tension of the carbon ribbon supply shaft and recycling shaft:

Ensure that the tension settings of the carbon ribbon supply shaft and recycling shaft are reasonable to avoid excessive tension causing the carbon ribbon to break.

If necessary, adjust the tension setting or replace the components of the carbon ribbon supply shaft and recycling shaft.

3、 Ink adhesion is weak or easy to erase

Choose specialized ink:

Use ink specifically designed for PET matte silver label paper to ensure that the ink can firmly adhere to the surface of the label paper.

If possible, ink types with higher adhesion can be chosen.

Improve the surface tension of printing materials:

Use a DaYin pen to test the surface tension of the printing material and ensure that it reaches the minimum value required for ink adhesion.

If the surface tension is insufficient, it can be improved by methods such as corona treatment or the use of transparent solvent based ink.

Increase drying or curing power:

If using processes such as relief printing or UV printing, ensure that the power of the drying or curing device is sufficient to fully dry the ink layer.

When printing large areas of solid graphics and text, special attention should be paid to checking the dryness of the ink and adjusting the drying power or speed appropriately.

4、 Static electricity problem

Increase workshop humidity:

Use humidifier or spray and other equipment to increase the humidity of the workshop to reduce the generation of static electricity.

Keep the relative humidity in the workshop within an appropriate range, usually recommended between 50% and 70%.

Use anti-static agent:

Apply a layer of anti-static agent coating on the printing material to improve its conductivity and reduce the generation of static electricity.

Pay attention to selecting anti-static agents suitable for PET matte silver label paper and ensure that they do not react chemically with ink.

Improve equipment grounding:

Check the grounding status of the equipment to ensure good grounding and eliminate static electricity accumulation.

Auxiliary equipment such as anti-static ropes and anti-static copper wires can be used to enhance the grounding effect.

5、 Other precautions

Regularly clean the printer:

Regularly clean the print head, drum, and sensors of the printer to ensure their proper functioning and reduce the likelihood of malfunctions.

Check the quality of label paper:

Ensure that the PET matte silver label paper used is of reliable quality and free from damage or deterioration.

If the quality of the label paper is found to be poor, replace it with a new one in a timely manner.

Training operators:

Train and guide operators to ensure they are familiar with the operation methods and precautions of the printer.

Remind operators to pay attention to the printing quality and effect during the printing process, and promptly identify and solve problems.

In summary, solving the problems of PET matte silver label paper during the printing process requires comprehensive consideration of multiple aspects, including adjusting printing parameters, replacing carbon tape and ink, increasing workshop humidity, using anti-static agents, and other measures. By taking these measures, printing quality and efficiency can be effectively improved, and the possibility of malfunctions can be reduced.
