How to judge the quality of thermal transfer printing film?

1. The color of the heat transfer printing film pattern is determined by the electroengraving plate and ink color matching. We know that the pattern is printed by the electroengraving plate through ink, so the depth of the electroengraving plate also has a great impact on the color effect. Secondly, there is no absolute value for ink blending. It all depends on the experience of the colorist. Of course, the exception is partial color, which can be blended directly through the ink factory. Another important point is the environmental protection of inks. Environmentally friendly printing is now advocated, and most products require environmental testing.

2. The degree of fusion between the heat transfer film pattern and the material used for hot stamping mainly depends on the matching value of the heat transfer film release agent and glue with the material. The simple understanding is that the pattern is easier to detach and has good adhesion after hot stamping. The glue used for hot stamping each type of heat transfer film is different for different materials.
