Poor Roller Transfer and / or Glazing

Rollers are improperly or inadequately cleaned

Thoroughly clean up with a good quality roller glaze remover. (To remove glaze, apply hot water to rollers after removing ink. This will remove gum glaze that is not soluble in standard wash-up solvents)

Rollers are improperly set; rollers are swollen or distorted

Adjust roller settings or check roller surface condition

Gum arabic and gum substitutes are in fountain solution; wetting agents have been used indiscriminately

Control use of additives and use proven fountain solution
