When the printer runs, the ink splits between the ink rollers of the printing press. The long ink forms long filaments. These filaments break into fine droplets that are scattered in mist and distributed in the air of the printing shop.
Reasons: (1) Printing speed is too fast. (2) Too much ink, the ink layer on the ink roller is too thick. (3) The ink is too long and sticky. (4) The ink roller is not properly installed or damaged.
Processing methods: (1) Reduce the printing speed. (2) Change the ink with high color density to reduce the amount of ink.
(3) Add wax additives to make the ink short and reduce the viscosity. (4) Check the ink roller and open the ink fountain smaller. Adjust the ratchet wheel to make the rotation faster.
