Dampening Tips
• If a transition roller connects the dampening system and the inking system (e.g., ALCOLOR and
other similar continuous-feed dampening systems), deactivate the transition roller.
• If the printing press has a pre-dampening function (for example, the Heidelberg Printmaster QM), set
a higher pre-dampening level.
• If there are short breaks during the setup phase, or when the paper stack is being replaced, you should
leave the dampening rollers engaged on the tray. If this is not possible, restart printing in the same
manner as in the initial start-up procedure.
Ink Tips
• For best results, use highly pigmented inks to keep the amount of transferred ink at a low level and
decrease the scumming effect.
• For optimum printing quality, do not mix ink with printing oil or any other printing agents that
decrease tackiness.
