Ink length refers to the ability to pull a filament from a can of ink. If an ink is too long, this could cause ink misting on press and if too short, this may result in piling on the blanket. Excessive heat buildup in the ink rollers and emulsification of fountain solution can contribute to ink misting. Make sure the ink rollers are well maintained, set correctly to minimize heat buildup, and promote good ink water balance. Contact you ink supplier for their assistance. A new formulation of ink can reduce or eliminate misting.
