How to deal with the messy ink of flexographic printing machine

During the printing process, if the flexographic printing machine has ink flying, it may affect the normal printing. Therefore, it is very important to find out the problem in time and solve it. So how to solve the problem of ink flying of flexographic printing machine?

The phenomenon of tiny droplets of ink flying in the air is called "ink flying", also called ink mist dispersion, which is a common fault of high-speed rotary letterpress printing machine. To slow down the "ink flying" phenomenon, you can increase the humidity of the printing workshop and use conductive ink such as water-based ink.

During the printing process, the paper is not easy to separate, the paper on the paper collection table is not collected evenly, or the paper on the paper feeding table is skewed and the overprint is not accurate, etc., which may be caused by static electricity. To eliminate printing static electricity, generally install an electrostatic eliminator on the printing machine to ionize the air around the printing machine, so as to neutralize the positive and negative static electricity on the paper. You can spray an appropriate amount of water mist around the printing machine or above the back of the impression cylinder to eliminate static electricity on the paper. In addition, increasing the humidity of the printing workshop is conducive to the elimination of static electricity.

Ink penetration refers to the phenomenon that the front print can be seen on the back of the printed sheet. To prevent ink penetration, you can choose to print on paper with high density, or increase the viscosity of the ink and appropriately reduce the printing pressure.

Therefore, the ink flying problem of the flexographic printing machine can be solved by these methods.
