What should I do if the color of BOPP thermal sensitive synthetic paper fades?

To address the issue of color fading in BOPP thermal synthetic paper, the following methods can be tried:

1、 Preventive measures

Choose high-quality products:

When purchasing, choose high-quality and stable BOPP color thermal synthetic paper to reduce the possibility of fading.

Control storage conditions:

Store BOPP thermosensitive synthetic paper in a dry, ventilated, and dust-free environment, avoiding direct sunlight and high temperature and humidity conditions.

Avoid long-term storage, as it may cause material aging and affect the durability of colors.

Device compatibility:

Confirm the compatibility of printers and other devices before use to ensure optimal printing results.

Correct operation and maintenance:

Correctly set various parameters of the printer, such as printing speed, printing density, etc.

Regularly inspect and maintain printing equipment to ensure it is in good working condition.

2、 Remedial measures after fading

Constant temperature heating method:

Place the faded BOPP thermosensitive synthetic paper in a constant temperature chamber, set the temperature between 75 ℃ and 100 ℃, and maintain it for about 10 minutes.

This method may help restore partially faded handwriting, but the effect may vary depending on the quality of the paper and the degree of fading.

High pixel photography and electronic enhancement:

If the handwriting is still not clear enough after heating, you can try taking photos with a high pixel digital camera.

Input the photos into the computer and use color difference recognition software to further enhance the readability of the handwriting.

3、 Precautions

Avoid excessive processing:

When taking remedial measures, excessive heating or processing should be avoided to avoid damaging the paper or causing other irreversible damage.

Timely replacement:

If the fading is severe and cannot be restored, it is recommended to replace it with a new BOPP thermal sensitive synthetic paper in a timely manner.

Consulting professionals:

In case of serious fading problems, it is recommended to consult paper suppliers or professional technicians for more professional advice and solutions.

In summary, to address the issue of color fading in BOPP thermal synthetic paper, preventive measures can be taken to reduce the possibility of fading, and appropriate remedial measures can be taken after fading to restore some of the handwriting. However, please note that these measures may vary in effectiveness depending on the quality of the paper and the degree of fading.
