We all know that making packaging bags is not very difficult, but printing packaging bags is quite difficult. So today, yltpacking will give you a detailed introduction to the two points that need special attention in packaging bag printing. So that everyone understands that printing packaging bags is also a very important thing. Not only that, but there are details that we must pay attention to. Let’s take a look at these two points that need special attention! 1. The printing of the packaging bag should be properly adjusted to the pressure of the roller. The rubber will be rolled up slightly inadvertently when the packaging bag is printed; if the ink color is too heavy, the rubber or roller will easily stick to the bottom. Therefore, the pressure of the cylinder should be reduced before printing, and the lining in the rubber should be reduced. In order to avoid sticking to the rubber and rolling rubber, add more additives or adhesives to the ink, avoid double sheets, multiple sheets and paper skew, to ensure uniform pressure, no need to roll the rubber. In printing, the height of the front gauge and the height of the side gauge should be adjusted according to the thickness. At the same time, the pressure of the pressure roller and the brush wheel on the plate should be adjusted. 2. The printing of packaging bags is the same as other printing products. The color of ink directly affects the printing quality. Packaging bags play an important role in the protection and decoration of items. The printing quality of packaging bags will directly affect people’s aesthetics and consumption. Therefore, when printing packaging bags, quality standards must be met. Rules must be accurate, otherwise their quality will be affected. When it is found that the condition is not good after starting up, it is necessary to check the feeding situation and the pressure of the paper roller and press roller in time; for thicker materials, the pressure of the press roller and brush roller should be greater. And check the time of material in and out and pulling time, find out and deal with problems in time to ensure accuracy.
