Ink drying

We are having problems with the drying of the inks on a Rioby 3404, especially in matte coated paper. We are using Toyo inks.
Any idea?

 

Check the conductivity of the water. Should read approx 1300

 

It's a waterless press...

 

Perhaps you have very high density or your powder not working properly, see your total area coverage be under 300% -280% is the best i think-, look at your TVI curves and switch ink vendor. We use sunchemical and are very good
