Nowadays, more and more cigarette-pack printing companies are paying attention to water-based inks. The application of water-based inks in China's cigarette packs has also improved. However, current water-based inks are mainly used in low-end applications where printing quality is not high. On the cigarette pack, the application on the high-grade cigarette pack is not optimistic, and there are still many cigarette pack printing companies who dare not get involved in the water-based ink field. So, what is the problem that limits the application of the water-based ink for the cigarette pack?
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.
After the ink is stored for a period of time, the upper part of the container is thin, the viscosity is small, and the color and concentration are relatively poor; the lower part is thick, the viscosity is large, and the color and concentration are relatively good. The gravure printing ink is a fluid which is thin and has a small viscosity, because the pigment is poorly dispersed in the binder; the density of the pigment or the filler is too large; and the precipitation is prone to precipitation in a long-term storage. All of these problems can affect the performance of the ink. Even after fully shaking, without affecting the conditions of use, this state of the ink can cause a bad impression to the customer and increase the burden on the worker.
