PET matte silver thermal label paper in the printing process of the cause of smudging?

PET matte silver thermal label paper in the printing process of the reasons may involve many aspects, the following are some possible causes and corresponding solutions:

First, possible reasons

1. Thermal paper quality problems:

If the PET matte silver thermal label paper used is of poor quality, or the paper is outdated, damp, and contaminated, it may lead to poor printing results, including fainting.

2. Print head problem:

Aging or clogging of the print head can affect the uniform ejection of ink, resulting in smudging of the printed content.

Inappropriately setting the print head temperature can also lead to smudging, as too high a temperature can accelerate the chemical reaction on the thermal paper, causing color diffusion.

3. Printer setup problem:

Improper Settings such as printing concentration and printing speed will affect the printing effect. Too high or too slow a concentration can cause the ink to spread on the paper, forming a halo.

4. External environmental factors:

Dust and dirt in the working environment of the printer may also have an impact on the printing effect, especially when these impurities are attached to the print head, which is more likely to lead to fainting.

5. Paper and carbon tape mismatch:

Although the PET matte silver thermal label paper itself is designed for thermal printing, in some cases, if an unsuitable carbon strip is used (especially the thermal transfer carbon strip), it may also appear during the printing process.

Second, the solutions

1. Check and replace thermal paper:

Ensure the use of fresh, dry, non-polluting and reliable PET matte silver thermal label paper.

Avoid using expired or damp paper.

2. Clean and inspect print heads:

Clean the print head regularly to ensure that its surface is clean and free of clogs.

Check whether the print head is aging, and if necessary, replace the new print head in time.

3. Adjust printer Settings:

According to the actual printing requirements, adjust the printing concentration and printing speed to the appropriate range.

You can try different combinations of Settings to find the best print results.

4. Improve the working environment:

Keep the printer working environment clean and tidy, and remove dust and dirt regularly.

Avoid placing the printer in direct sunlight or in a hot and humid environment.

5. Make sure the paper matches the carbon strip:

Confirm that the type of carbon tape used is compatible with PET matte silver thermal label paper.

Consult a supplier or professional for advice on paper and carbon strip matching when needed.

In summary, the reasons for the fainting of PET dumb silver thermal label paper in the printing process may be various, and it needs to be investigated and solved according to the specific situation. By taking the above measures, the printing quality can be effectively improved and the smudge phenomenon can be reduced.
