At present, the flexographic process is the fastest growing printing process in the world. As far as the label industry is concerned, the US flexographic printing accounts for 85% of the label field; the European flexographic printing starts later than the US, and the current market share is about It is 45% and the momentum is rising rapidly. Flexographic printing is currently in its infancy in Asia, and many manufacturers are launching new flexo presses.
Therefore, I think the heater plays an important role in graphic production. However, some problems have also been presented during the practice test. For example, the problem of the copper plate of the printer is not well controlled, and it is not easy to dry, simple to fade, slow, the adhesion of the ink is not strong, and some papers are printed with ink. So is there a better way to deal with these problems now? The answer is yes.
Imitation printing ink is also weakly soluble ink, so many people are worried that this ink is corrosive, so it is daunting to him. Yes, since it is dissolved in ink, the corrosiveness is inevitable, but the pH of this ink is not very high, weak base, and some taste. In fact, we use the general ink does not rule out the damage to the machine nozzle. If the quality of the ink is not good, it will damage the nozzle. I used a company's pigment ink to break the nozzle. So the question is how to look at this problem, if we are getting a good reward, it is still possible to dedicate something.
At the same time, it also affects the gloss and ink transmission of the ink. The amine compound mainly maintains the alkaline PH value of the aqueous ink, so that the acrylic resin provides better printing effect. The water or other organic solvent mainly dissolves the resin, adjusts the viscosity and drying speed of the ink. The auxiliary agents mainly include: defoaming agents, retarders, stabilizers, and dilute agents.
