Abstract

Ink misting happens when the ink flies away from the printing rollers during oscillation.

Suspect 1 – Ink

The ink tears apart in the nip between the rollers. The droplets produced fly around due to their momentum and air movements and contaminate the environment around the printing press. In serious cases, fine aerosols can form, threatening the health of employees in the pressroom.

Misting may appear in 2 different forms

  1. Constantly while printing
  2. While roller washing

Fix:

  1. Talk to your ink supplier to receive a TACK (inner cohesion)-optimized ink

    Suspect 2 –  Too much solvent/roller washing detergent applied while rinsing

    Fix:

  2. Optimize automatic roller washing programs
  3. Reduce amount of wash-up solution while rinsing the rollers
  4. Check roller settings. No-contact in between some rollers may also cause ink misting
