How to prevent the surface of PET matte silver paper from being scratched after printing?

To prevent the surface of PET matte silver paper from being scratched after printing, you can start from many aspects, including choosing the right printing method, optimizing the printing process, using the right auxiliary materials, and strengthening post-processing and maintenance. Here are some specific suggestions:

1. Choose the right printing method

Thermal transfer printing: Use resin-based carbon tape for thermal transfer printing, because the resin carbon tape has heat resistance, solvent resistance and scratch resistance, which can better protect the surface of PET matte silver paper from scratching.

2. Optimize the printing process

Control the printing pressure: maintain a uniform and stable printing pressure to avoid excessive pressure resulting in damage to the material surface.

Adjust the drying speed of the ink: for the adhesion problem caused by too fast drying of the ink, you can appropriately increase the slow drying agent, and reasonably control the printing speed to prevent the ink from drying too much.

Clean the guide roller and brush: Periodically check and clean the printing machine to ensure that the guide roller, electrostatic brush and other parts have no foreign bodies, no sticky dirty bumps, to avoid scratching the surface of the material.

3. Use the right supporting materials

Self-adhesive material pad paper: Paste a layer of self-adhesive material on the surface of the paper wheel (PET material is recommended) to reduce the direct pressure of the paper wheel on the surface of the material and prevent pressure marks.

Protective film: After printing is completed, a protective film can be covered on the surface of PET matte silver paper to isolate external scratches.

4. Strengthen post-processing and maintenance

Correct film threading and cutting: Ensure that the film is properly fed to avoid unnecessary scratching caused by incorrect film threading lines. At the same time, pay attention to avoid direct contact with the surface of the material with sharp tools during the cutting process.

Environmental control: Keep the workshop environment clean, avoid sand, foreign matter, etc., into the workshop to reduce the potential scratch risk on the surface of the material.

Staff training: Strengthen the training of staff operation skills to ensure that employees can perform operations in accordance with standards and norms to reduce scratch problems caused by human factors.

5. Other precautions

Avoid mechanical scratches: During transportation, storage and use, avoid direct contact between PET matte silver paper and other hard or sharp objects to reduce the risk of mechanical scratches.

Choose the right detergent: When cleaning the surface of PET matte silver paper, you should choose a non-corrosive detergent suitable for PET material, and avoid the use of cleaners containing pigments or chemicals to cause surface damage.

To sum up, preventing the surface of PET matte silver paper from being scratched needs to be comprehensively considered and implemented from many aspects. By choosing the right printing method, optimizing the printing process, using the right auxiliary materials and strengthening post-processing and maintenance, the surface quality of PET matte silver paper can be effectively protected.
