In flexographic printing production, due to problems such as paper, anilox rollers, ink, printing pressure and other packaging logistics, often encounter large-scale solids, flowers and other phenomena. In packaging and printing, when using paper with low surface smoothness and easy to fall off, such problems are especially serious. A flexographic printing machine always feels that the ink layer is insufficient in daily production, especially when printing large areas. Thick and full. Adjust the ink viscosity by â‘ , increase the printing pressure, and adjust by two methods. This phenomenon is alleviated at a low speed of 30 m / min to 50 m / min. However, when the speed is gradually increased by more than 80 m / min, this phenomenon is restarted. Appears, and the faster the speed, the more obvious the phenomenon of false hair. Because the anilox roll preparation restricts the packaging of washing supplies and cannot be printed again, it can only be solved from other aspects. It is observed that the anilox roll blade of the printing machine is a reverse blade. Due to the shearing force of the ink, and because the printing pressure cannot be too large, the ink is actually reduced. With this idea, you should consider increasing the amount of ink, so adjust the direction of the doctor blade to install it with a positive doctor blade, start up Trial printing, this phenomenon has been improved, and the effect is more obvious at high speed. Since then, in production, we have chosen to install the forward or reverse scraper according to the nature of the printing, printing plate, etc., such problems rarely occur. However, this method should be used flexibly in accordance with the requirements of print quality in actual application.
