Factors affecting the effective anti-penetration of sublimation protective paper

The anti-penetration effect of sublimation protective paper in thermal transfer is directly related to the quality of the transferred pattern. Its effective anti-penetration is affected by many factors.

1. Temperature and pressure settings of thermal transfer equipment

Different models of sublimation protective paper have different tolerance ranges for temperature and pressure. Taking the common thermal transfer machine as an example, if the temperature is lower than the minimum threshold required by the protective paper, the ink sublimation is insufficient, and it is difficult to transfer it to the target material completely, and the pattern is prone to incomplete; if the temperature is too high, the protective coating of the protective paper may be destroyed, causing the ink to penetrate and the pattern to become blurred. The same is true for pressure. If the pressure is insufficient, the contact between the ink and the protective paper and the target material is not close, and the transfer effect is not good; if the pressure is too high, the protective paper may be damaged and lose its anti-penetration ability.

2. The quality of the protective paper itself

The quality of protective paper on the market is uneven, and high-quality protective paper uses advanced production technology and superior raw materials. Its multi-layer composite structure is tight, and the special coating is uniform and firm, which can effectively resist ink penetration. On the other hand, inferior protective paper has poor raw materials, easy-to-fall-off coating, and loose structure. It is very easy for ink to break through the defense line during the thermal transfer process, failing anti-penetration. For example, protective paper produced by some small workshops frequently has penetration problems under normal thermal transfer conditions due to rough craftsmanship.

3. Humidity of the operating environment

In a humid environment, protective paper easily absorbs moisture, the paper structure becomes loose, and its anti-penetration performance is greatly reduced. When the moisture content is too high, the water evaporates due to heat during the thermal transfer process, which may interfere with the sublimation and transfer of the ink, change the diffusion path of the ink, and thus cause penetration. For example, in the rainy season in the south, if the humidity control of the workshop is not paid attention to, the anti-penetration effect of the protective paper in the thermal transfer will be significantly reduced.

4. Properties of the target transfer material

Materials with rough surfaces and large pores have a strong adsorption capacity for ink. If the protective paper is not selected properly, the ink is easy to penetrate along the pores of the material, affecting the quality of the pattern. Therefore, before the thermal transfer operation, it is necessary to comprehensively consider the equipment parameters, the quality of the protective paper, the humidity of the operating environment, and the characteristics of the transfer material to ensure that the sublimation protective paper can effectively play an anti-penetration role and achieve high-quality thermal transfer.
