qm46 ink not drying

I am Having some problems with ink not drying fully I am runnning a solution of 4 % solution and 3 % alcohol per gallon Any help would be appreciated. Ink does not offset untill cutting.

 

Why are you running alcohol ?

 

it was recomended by the ink co. we weren't running any and still having the problem we switch inks still the same but not quite as bad

 

tried a solution

I tried a solution mix of 2% and no alcohol and will have to see how it works in the morning

 

Put grapho dryer in the ink 2oz per lb.

 

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!
