6. surface tension

ink surface Beijing University of chemical technology also cooperates with Beijing Institute of Aeronautical Manufacturing Engineering and Hangzhou Chaoyang Rubber Co., Ltd. the tension is related to the transfer performance of the ink and the stability of the imprint on the substrate. This relationship is more prominent when printing on smooth materials, especially on plastic surfaces. For example, when the surface tension of the ink is greater than the surface tension of the printing surface, the imprinting will shrink, and even fish eye shaped holes will appear; If the surface tension between the printing surface and the ink is similar, and the surface tension of the plate is generally smaller than that of the printing surface, the printing will be blocked. In these cases, the surface active agent, microcrystalline paraffin, silicide, etc. can be added, and the data shall be recorded during the test to adjust, so that the surface tension of the ink is equal to or less than the surface tension of the printing surface, so as to obtain a good printing effect
