Solution

Ink picks up the fiber or the coated layer from the paper surface.

INK

¡Ü High tack of ink.

¡Ü Raised viscosity of ink on the press machine

¡Ü Add 2-5% more compound in order to reduce tack of ink.

¡Ü Replace with low tack ink.

¡Ü Spray some inhibitor.(anti-skinning agent.)

 

PAPER

¡Ü Low surface bonding strength.

¡Ü Due to poor water resistance, surface bonding strength of paper is deteriorated by dampening water.

¡Ü Change with pick-resistant paper.
 

PRESS

¡Ü Too much amount of dampening water.

¡Ü Too much impression pressure.

¡Ü Ink is tacky due to low press room temperature.

¡Ü Tack of ink on the roller increases due to too long downtime of press.


¡Ü Adjust the amount of dampening water.

¡Ü Adjust the impression pressure.

¡Ü Spray inhibitor when the press stops for a long time.
