The resolubility of temperature sublimation refers to the redissolving ability of the ink after printing and drying when it encounters the solvent. Usually, the following methods can be used to compare and judge the degree of resolubilization of the ink: cut two printed films (printed with different inks respectively) ) flat on the desktop, drop two drops of ethyl acetate on the printing ink layer respectively, after 3 or 4 seconds, stand the two films upright, the ink flowing down more means the resolubility is stronger, and the ink is more Less downflow indicates weaker resolubility.
There is currently no clear quantitative index for the resolubility of ink, and the resolubility of inks from different manufacturers may have obvious differences. Because the resolubility of ink has a certain influence on the quality of printed and compounded products, the resolubility of ink is an important indicator of ink quality, and has a non-negligible impact on the printing and compounding quality of flexible packaging composite materials. sublimaiton transfer paper supplier industry There are concerns about this, but it is difficult to make a clear theoretical explanation to reduce the adverse effects on product quality.
