Thermal transfer paper performance

Thermal transfer paper performance requirements. The transfer paper is an intermediate ink-bearing carrier for thermal transfer. It not only requires good ink absorption performance, but more importantly, it has good ink release performance under certain conditions, and the ink The coating should have high uniformity. It is mainly reflected in the physical requirements: high surface smoothness, so that the color ink can be uniformly attached; the paper is of moderate tightness, and the absorbency is appropriate; the surface strength and toughness meet the process requirements, and the tearing of the paper after printing will not produce paper base fuzzing, graphics and text Paper hair sticking phenomenon; strong water resistance, the paper base will not collapse when water treatment is needed for tearing paper after printing; high temperature is not easy to wrinkle, shrink and yellow; it can withstand printing pressure, and the paper structure changes little. Thermal performance requirements: good heat resistance of the substrate, the lower the heat resistance, the smaller the thickness, the better the heat transfer performance; control the smoothness of the substrate, the higher the smoothness, the lower the heat resistance; good heat resistance The substrate printing requires time to be able to withstand the heat and high temperature of the press plate without affecting the various properties; excellent anti-seepage ability to prevent reverse penetration of ink to the paper base and affect the transfer rate of dyes.
