From the point of printing process, pad printing inks and screen printing ink and no similarities, screen printing ink performance is under pressure from scraper mechanical structure, and pad printing ink more is transferred to the nature of the blanket.
offset printing ink metastatic and screen printing ink plastic should be the ideal pad printing ink. Screen printing ink in order to achieve its permeability, it is necessary to add some lubricants, but the pad printing ink don't need such a composition. In order to realize the deinking of pad printing ink, printing ink to add certain materials, such as mold release agent, and don't need to screen printing ink. Screen printing ink of the ink layer thick, handwriting, to achieve the same effect, pad printing ink color concentration must be high.
in screen printing fabric printing field generally use water-based ink, but for now, in the printing industry is difficult to use water-based ink, this is another difference of them. There are two reasons caused the defect of pad printing, is a steel version of the poor water resistance, use water-based ink easily eroded. , of course, if we change the resin version, can eliminate this factor, but the glue head metastatic could be limited, to make silicone rubber transfer enough water-based ink has the certain difficulty.
pad printing ink on the surface of the rubber pad printing head, for keep the pad printing ink has a good enough delay sexual activity, otherwise, the ink imprinting are likely to become unclear. Plastic head, on the other hand, the surface of imprinted itself cohesion to significantly greater than the surface tension of the silicone rubber, and has the function of mold, such as thermal transfer film thermal transfer printing ink on it. Pad printing ink completely transferred to the product surface is one of the most important requirements for pad printing ink, but the ink completely transfer is only an ideal, in general, the ink can transfer is 86%. Despite the initial screen printing ink pad printing ink is used in place of the, but cannot say that pad printing ink is the screen printing ink, ink theory is suitable for all the printing process, but different printing process and detailed requirements.
