What are the common causes of quality problems in PET thermosensitive matte silver paper?

The common reasons for the quality problems of PET thermal matte silver paper mainly include the following aspects:

1. Material and matching problems

Thermal paper quality is not good: Some cheap thermal paper may have the problem of uneven ink penetration, resulting in blurred printed text. In addition, the thermal layer formula of the thermal paper will also directly affect its color rendering effect and stability.

Matching of PET material and carbon belt: If the material of PET label does not match the model of carbon belt, it may lead to poor printing effect, such as unclear font or missing.

2. Problems with the printing device and Settings

Not enough printing temperature: Thermal printers need a certain temperature in order for the ink to fully melt and penetrate the paper. If the temperature is not set properly or the printer is not heated enough, it will lead to unclear printing.

Print head aging or blockage: A print head that is used for a long time or is not cleaned in time may experience aging or blockage, affecting the normal ejecting of ink, thereby reducing the print quality.

Printing speed is too fast: In the case of printing speed is too fast, the ink may not be able to penetrate fully into the paper, resulting in an unclear printing effect.

Improper setting of printing concentration: the setting of printing concentration has a direct impact on the printing effect. If the concentration is set too high or too low, it may lead to a decline in print quality.

3. Storage and environmental factors

Thermal paper storage environment is improper: thermal paper should be stored in a dry, avoid direct sunlight environment. If the storage environment is humid or the temperature is too high, it will accelerate the decomposition of color products on the thermal paper, resulting in fading or blurriness of the writing.

Long-term placement: Even if stored in a suitable environment, thermal paper placed for a long time may also fade due to the natural decomposition of color products.

4. Other factors

Printer structure problems: In some cases, the structural design of the printer may not be suitable for a specific type of thermal paper, resulting in poor printing results. At this point, it may be necessary to adjust the printer structure or replace the printer suitable for this type of thermal paper.

In summary, the reasons for the quality problems of PET thermal matte silver paper are various, involving materials, equipment, Settings, storage environment and many other aspects. In order to solve these problems, it is necessary to consider various factors comprehensively and take corresponding measures to improve and optimize.
