Does the ink concentration of UV printers have a significant impact on the printing effect?

      Some customers may have a doubt during printing and processing. When using a UV printer for printing, is it better to add ink with a higher concentration? The answer is no. When adding ink to a UV printer, we must mainly adjust the concentration of the ink, so that we can print with good results and protect the ink supply system of the UV printer. Therefore, the concentration of the ink is very important. As for how to adjust the ink concentration well? Below, the editor will give you a good introduction.

      During the printing process of UV printers, if the water supply is too large, it will cause an increase in the ink supply to the layout, thickening of the ink layer, severe ink emulsification, and result in dull and dull printing. In the production process, in order to reduce startup waste, UV printers usually increase the water level to 150% of the normal value when turned on. After normal printing, the UV printer should gradually reduce the water level to the normal value to ensure clear graphics, saturation, and gloss.

     The control of ink balance in the printing process is related to many aspects. For example, the ratio of ink volume to water volume adjustment, the properties of the dampening solution itself, the concentration and temperature of the dampening solution, the properties of the ink itself, the pressure of the ink roller, environmental temperature and humidity, and so on. On older machines, control over these aspects is mostly based on intuition and experience, with significant variability. In actual printing, it is easier to detect low moisture content. Because the moisture content in the layout is too low to a certain extent, the layout will become dirty. So the occurrence of ink imbalance is mostly due to excessive water content. If not adjusted in a timely manner, it can cause severe emulsification of the ink.

      UV printers use UV ink, which belongs to weak solvent ink, has low volatility, is green and environmentally friendly, and is a special solid ink technology that dries immediately, is readily available, has no printing quantity limit, is very convenient, and is favored by the market. During the printing process, we must pay attention to adjusting the balance of ink and wash.

      Finally, it should be noted that when purchasing ink, it is necessary to buy it directly from the manufacturer of Tuchuang Intelligent UV Printer. Don't buy inferior ink just for the sake of small discounts, as this not only causes the printed material to not print, but also damages the nozzle of the UV printer.
