The relationship between screen Printing and Ink

In the field of printing, why can't other forms of printing (including lithography, letterpress, gravure printing and even emerging high-tech printing, such as computer jet painting, sublimation printing, digital printing, etc.) be integrated into high technology (participating in the operation of high-tech equipment) in addition to screen printing? This is a problem worthy of study. In addition to screen printing, a special screen printing form, the rise of special functional ink is a factor that can not be ignored. Throughout the high-tech screen printing products, whether it is semiconductor (CdS/CdTe) and electrode (Ag,C,Ag) in solar cells In) special functional ink, or thin film switch manufacturing technology silver (pulp) ink, carbon (pulp) ink, insulation ink; SMT Pb/Sn ink; printed circuit board manufacturing technology anti-electroplating ink, anti-corrosion ink, welding ink. We seem to be able to say: without screen printing workers on special functional ink research and innovation, screen printing products of high-tech can only be an unrealistic fantasy.
