■ Ink is drying too slow
■ Use faster drying solvents
■ Decrease the printing speed
■ Increase air flow and temperature of blower.
■ Rewind pressure is too high
■ Decrease the rewind pressure
■ Over plasticized inks
■ Contact ink supplier.
■ Add anti-blocking compound.
■ Film is treated on both sides
■ Use one side treated film; or
■ Use anti-blocking compound.
■ High plate impression
■ Check and reduce plate impression.
■ Excessive ink is transferred to the plate
■ Reduce anilox volume; and/or
■ Check doctor blade.
■ Poor treatment of substrate
■ Treat substrate to appropriate treatment level
■ Improper ink for the substrate
■ Contact ink supplier and request for the right ink for the substrate.
■ Excessive impression pressure
■ Adjust to “kiss” impression
● Previous ink is not fully dried
● Adjust the previous ink by:
– Reduce viscosity
– Use faster drying solvent
– Increase blower volume and temperature.
■ Ink is fast drying and drying up in the anilox roll
■ Use a slower drying solvent
■ Not enough ink going into the anilox cells
■ Reduce press speed; or
Reduce ink viscosity to allow faster entry of ink into the anilox cells.
