    Alcohol is a wetting agent for bareback type dampening it has nothing to do with ink drying.

    Is this on every job? It could be the paper, ink is sitting on the coating and not absorbing into the paper. Maybe try running a test on 2 or 3 different stocks.

    you should not have to add drier. I have not used drier in years.(30 yrs. exp.) If your ink is not drying ,you could be running too much water. Try this test. Turn damps off and run a few dry solids. Let it dry 48 hours and check it. If the ink is dry then the ink is ok. If it is not dry,switch ink companies!
