From the point of view of the printing process, printing ink and screen printing ink and no similarities, screen printing ink is mechanical structure under the squeegee pressure, and pad printing ink more is be transferred performance summary nature. Transfer of offset printing ink and plastic net printing ink pad printing ink should be ideal. Screen printing ink in order to realize the transmission and add a lubricant is necessary, but printing ink don't need such components. In order to achieve printing ink deinking, printing ink to add some material from the agent and the like, and screen printing ink is not required. Screen printing ink layer thick, bold handwriting, to achieve the same effect, color printing ink will need high concentration. 

Screen printing fabric printing field in the widespread use of water-based ink, but at present, in the printing industry is difficult to use water-based ink. This is another difference between them. There are two reasons for the defects of printing, a steel plate is water resistance is not good, water ink easily eroded. Of course, if we replace the resin version, you can rule out this factor, but the transfer of the head of the gel will be limited, to allow the transfer of silicone rubber enough water ink has a certain degree of difficulty. 

Pad printing ink in printing plastic head surface morphology keep printing ink requires a good enough activity lag. Otherwise, imprinted ink is likely to become unclear. On the other hand, the formation of the surface of the adhesive tape itself is significantly greater than the cohesive force of the surface tension of the silicone rubber, and has an off type function, such as thermal transfer film above the thermal transfer printing ink. Printing ink completely transferred to the surface of the product is the most important requirements of the pad printing ink, but ink transfer is the ideal situation, generally speaking, the ink can be transfer 86%. Although the initial printing ink is used to replace the screen printing ink the, but can not say that the printing ink is screen printing ink, ink theory for all the printing process, but the different printing processes and detailed requirements. Is precisely the printing ink of the above requirements prompted many ink manufacturers in an attempt to create a special printing ink, currently, only Germany Marabu company and Dujo company launched the special printing ink, is improved based on the screen printing ink of the.
