Anilox volume is too deep for dot size and an excessive amount
Reduce anilox volume or increase plate dot size
Ink film is too thick for plate screen
Reduce ink film thickness by lowering ink viscosity, increasing ink metering or decreasing anilox volume
Ink formula our of balance, affects film splitting/transfer
Check solvant blends for alcohol/ester balance. For clean printing, the rasin structures must have the correct solvants.
Ink is drying too fast
Add slower drying solvents, check ink formulations
Ink is flooding plate dots due to loose ink metering or worn doctor blades
Check and adjust ink metering, Check and replace doctor blade if indicated.
