With the improvement of living standards, people have put forward higher requirements for food packaging. Ink as a printing material, when it is applied to food packaging, must adhere to the principle of no transfer. Food packaging should not use conventional inks. The printer must ensure that all the solvents in the ink after printing are volatilized. The inks require thorough curing and meet the corresponding standards in the application industry. 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. The organic amine volatilizes slowly, so the stability is good, but the price is expensive; the ammonia water is cheap, but the volatilization is fast, and it must be replenished in time; the inorganic alkali solution is cheap and does not volatilize, but the performance is poor. At present, the water-based ink used in the industry basically adopts one of the first two processes, or combines the two processes, using both an organic amine and ammonia water, in order to balance performance and cost. At present, water-based inks with high quality requirements do not need to periodically monitor their pH values, and do not need to add stabilizers frequently.
