Ink Knowledge: Introduction to Specialty Functional Inks

In the field of printing, why products other than screen printing can be integrated into high technology (participation in the operation of high-tech equipment), and other forms of printing (including lithography, letterpress printing, gravure printing, or even emerging high-tech printing such as computer inkjet printing , sublimation printing, digital printing, etc.) but not? This is a very worthwhile issue to study. In addition to screen printing, this special type of screen printing, the rise of special functional ink is a factor that cannot be ignored. Throughout the high-tech screen printing products, whether it is the special functional inks of semiconductors (CdS/CdTe) and electrodes (Ag, C, Ag+In) in solar cells, or the silver (plasma) in membrane switch manufacturing technology Ink, carbon (slurry) inks, insulating inks; Pb/Sn inks in SMT; plating inks, resist inks, solder mask inks in printed circuit board manufacturing technology... We can seem to say: No screen printers For the research and innovation of special functional inks, the high-tech of screen printing products can only be an unrealistic fantasy. Due to limited space, the author will discuss the special functional inks in screen printing in the future.

In the 21st century, the competition in the printing field will become even more intense. In addition to the increasingly fierce competition between the traditional four printing formats: flat, convex, concave, and net (hole), the newly emerging computer inkjet, sublimation printing, and inkjet The challenge and impact of printing, digital printing, and so on, which people call it a new type of printing technology, will not be based on people's will. Faced with such a severe situation, the screen printing industry should have a sober understanding. Of course, we will not be easily defeated. Apart from our “sticking to” positions and striving to innovate in the traditional field of screen printing, we must do a better job of screen printing in high-tech fields where other forms of printing are incapable. At the same time, as screen printing, there is still a unique and broader space for development. We should take the initiative to target the high-tech field, aim at the pillar industries in the era of knowledge economy, and target screen printing areas that have not yet entered the field. Since high-tech needs screen printing, and screen printing has such strength, why don't we work hard or fight hard? Faced with the fierce competition in the domestic printing industry, sometimes we will see a very sad scene, that is, for the sake of competition, mutual bargaining between printing companies, this kind of low-level fratricidal "competition" Not enough. The ancient saying goes: "Retreat from one step, broaden the sky." Yes, for those who are quite talented and economically capable, especially those screen printing companies that are already immersed in high-tech silk screen printing, why can't they take a step back? Why can we not stand upright at the forefront of high-tech screen printing? Gradually emerge from the whirlpool of disorderly or malicious competition among domestic printing companies and look at the international market. As long as we dare to fight, dare to innovate, and dare to make waves in the international market, we will surely obtain greater and better economic and social benefits.
