Factors affecting the isolation and protection effect of sublimation protection paper

1. The quality of the protective paper itself

Material: Different materials have a great influence on the isolation protection effect. High-quality thermal sublimation protective paper is usually made of special high-temperature resistant and wear-resistant materials, which can better withstand the high temperature and pressure during the thermal sublimation process and provide effective isolation.

Thickness: The thickness of the protective paper will also affect the isolation effect. Generally speaking, thicker protective paper can provide better physical isolation and prevent the ink from directly contacting the heating equipment or other objects.

2. Environmental factors of use

Temperature and pressure: The temperature and pressure in the thermal sublimation transfer process are key factors. If the temperature is too high or the pressure is too high, the isolation performance of the protective paper may be reduced. High temperature may cause the protective paper to deform and soften, thereby losing the isolation effect; while excessive pressure may make it easier for the ink to penetrate the protective paper.

Therefore, when using thermal sublimation protective paper, the appropriate temperature and pressure must be set in strict accordance with the equipment requirements to ensure the isolation effect of the protective paper.

Humidity: Environmental humidity will also affect the isolation protection effect of the protective paper. In a high humidity environment, the protective paper may absorb moisture and become soft, reducing its heat resistance and isolation performance. In addition, a humid environment may also cause uneven ink diffusion and affect the transfer effect. Therefore, sublimation protective paper should be used in a dry environment as much as possible and stored properly to avoid moisture.

3. Transfer operation factors
Transfer time: Too long a transfer time may cause the protective paper to be overheated and reduce its isolation effect. Different transfer materials and patterns require different transfer times, which should be adjusted according to actual conditions. If the transfer time is too long, it will not only affect the performance of the protective paper, but may also cause the transferred pattern to be too dark or smudged.
Transfer material: The nature of the transfer material will also affect the isolation effect of the protective paper. For example, some special transfer materials may require higher performance protective paper to achieve a good isolation effect. If the surface of the transfer material is uneven, has burrs or other defects, it may also damage the protective paper and affect the isolation performance.

When selecting a transfer material, its compatibility with the protective paper should be considered to ensure the best isolation protection effect.
