How to preserve colored thermosensitive synthetic paper to ensure its quality?

To preserve the quality of colored thermosensitive synthetic paper, the following measures can be taken:

1、 Environmental condition control

Temperature and humidity:

Store colored thermosensitive synthetic paper in an environment with a temperature of 23 ± 2 ℃ and a relative humidity of 60%~70% (or 65% ± 5%) to minimize the aging rate of the paper.

Avoid prolonged exposure to high or low temperature environments, as well as avoiding high humidity that can cause paper to become damp.

Avoid light:

Avoid direct sunlight exposure on colored thermosensitive synthetic paper, as ultraviolet radiation can accelerate the decomposition of chemicals in the paper, leading to fading of handwriting.

Store the paper in a cool, dark place, or use a light blocking material (such as a black plastic bag) for packaging.

2、 Packaging and storage methods

Sealed packaging:

Seal and package colored thermosensitive synthetic paper with moisture-proof paper, film, or plastic bags to reduce the erosion of air, moisture, and dust on the paper.

For already printed paper, it is recommended to stack it in layers and avoid being too heavy to prevent glue from sticking through.

Vertical stacking:

For color thermal synthetic paper packaged in rolls, it should be stacked vertically to prevent curling and deformation.

Flat paper should be stored flat, with a height of no more than 1 meter per board, and the goods should be at least 10 centimeters above the ground to prevent moisture and contamination.

3、 Chemical protection

When storing and using colored thermosensitive synthetic paper, contact with chemicals should be avoided as much as possible, as these chemicals may damage the surface coating of the paper, resulting in poor printing performance or inability to print.

4、 Regular inspection and cleaning

Develop the habit of regularly checking and cleaning printing equipment to maintain its cleanliness and normal operation. This helps ensure that the paper can print clear and beautiful printed materials normally and stably during the printing process.

Regularly check the storage status of colored thermal sensitive synthetic paper, and replace it in a timely manner if there is yellowing, deformation, or other issues to avoid affecting the printing quality.

5、 Special protective measures

If it is indeed necessary to store documents or labels printed on color thermal sensitive synthetic paper for a long time and there are high requirements for storage quality, plastic sealing or copying/scanning methods can be considered for protection. However, it should be noted that plastic wrapping may accelerate the aging of paper (as the wrapping process may require heating), so cold mounting should be used, and non adhesive plastic film and cold mounting film should be used for packaging. Copying or scanning, on the other hand, is the most reliable long-term preservation method for saving the content on paper as an electronic document.

In summary, by controlling environmental conditions, adopting appropriate packaging and storage methods, avoiding contact with chemicals, regularly inspecting and cleaning printing equipment, and taking special protective measures, colored thermosensitive synthetic paper can be effectively preserved to ensure its quality.
