What are the precautions to take when printing transparent thermal label paper?

In the process of printing transparent thermal label paper, the following precautions should be taken to ensure the printing effect and the durability of the label:

1、 Paper selection and processing

Paper quality: Choose high-quality and durable transparent thermal label paper to ensure clear and long-lasting printing content. High quality thermal paper can be stored for a longer period of time, some even up to 30 years or longer.

Avoid contact with chemicals: Thermal paper should avoid direct contact with chemicals, as certain chemicals may damage the coating on the surface of the paper and cause the printed content to fade.

Layered stacking: For already printed transparent thermal label paper, it should be stacked in layers to avoid excessive weight causing glue penetration and adhesion, which may affect the storage effect.

2、 Printing equipment and environment

Check printing equipment: Regularly inspect and clean printing equipment to ensure its cleanliness and normal operation, and avoid a decrease in printing quality caused by equipment problems.

Control printing environment:

Temperature: The ideal labeling environment temperature should be maintained between 10 ℃ and 25 ℃. If the temperature is too low, the stickiness of the adhesive label will be greatly reduced, resulting in the label not being firmly attached, lifting or even falling off. Meanwhile, avoid high temperature environments as high temperatures can accelerate chemical reactions on thermal sensitive coatings, leading to fading of printed content.

Humidity: Keep the environment dry and avoid excessive humidity that can cause paper to become damp, thereby affecting the clarity of printed content.

Lighting: Avoid direct sunlight, as the ultraviolet rays in sunlight can accelerate the aging of the thermal sensitive coating, causing the printed content to fade.

3、 Printing settings and operations

Print head temperature: Adjust the temperature of the print head to adapt to different paper types to ensure optimal printing results. Low temperature may result in unclear printing, while high temperature may damage the paper or accelerate fading.

Printing speed: Choose an appropriate printing speed to ensure clear printing content and prevent overheating of the print head due to excessive speed.

Avoid glue sticking: For non stick printing paper, avoid using glue or transparent adhesive as these methods may accelerate the disappearance of handwriting.

4、 Storage and protection

Sealed packaging: After each use, the remaining transparent thermal label paper should be resealed and packaged to maintain its good storage condition.

Using transparent plastic bags or folders: Seal and package the printed transparent thermal label paper in a transparent plastic bag or folder to effectively prevent dust and other pollutants from entering.

Avoid long-term exposure: Avoid exposing printed labels to harsh environments such as high temperature, high humidity, direct sunlight, etc. for a long time.

5、 Other precautions

Pay attention to changes in paper quality: During the printing process, pay attention to observing the quality changes of transparent thermal label paper. If unclear printing or uneven color is found, the paper should be replaced or the equipment should be checked in a timely manner.

Choose an appropriate printer: If you need to store labels or documents for a long time, you can consider using a heat transfer label machine/printer or inkjet, laser printer, etc. These machines print images with more durability.

In summary, when printing transparent thermal label paper, attention should be paid to paper selection and handling, printing equipment and environment, printing settings and operation, storage and protection, and other related matters. By following these precautions, it can be ensured that the printed labels are clear, durable, and meet the needs of various application scenarios.
