How to control the color tone of color printed packaging bags During the printing process of composite packaging bags, the ink film color of color printed packaging bags mainly depends on the ink concentration and handling rate during the printing operation. Regarding specific substrates or ink for specific operations, the concentration of ink for operations is relatively fixed, and the handling rate depends on factors such as ink viscosity, as well as printing speed.

If the temperature and humidity change the room temperature, and the liquid temperature of the ink changes significantly, the flow state will change, and the color tone will also change accordingly. This is because temperature changes affect the viscosity of the ink. At the same time, the dry climate of high temperature and low humidity will have a significant impact on the ink handling rate in high gloss areas.

Therefore, when printing products, it is necessary to control the temperature and humidity of the printing workshop no matter how. In addition, when using ink in winter, it is necessary to preheat it in advance to reduce the temperature change of the ink itself. This kind of scene is prone to occur in various thick turbid materials with varying densities, such as light colors and organic and inorganic pigments. Especially when the ink in the ink tray flows too slowly, sedimentation will promote the separation of synthetic colors, so it is important to pay attention to the circulation of the ink.

In addition, if the mixing is not sufficient during color mixing, the concentration of a certain color tends to increase as printing progresses. Therefore, mechanical or other methods such as a dissolution machine should be used for sufficient mixing before formal printing. Due to long-term printing, changes in the solvent composition of the ink, or the mixing of water in the air with the ink causing ink deterioration, resulting in color deterioration.
