my experience with the older dahlgren dampening was a positive one. but then again they were coming out as a retrofit for a conventional ducted dampening system so any continuous flow system would be an improvement. once the press manufacturers began engineering their own continuos flow dampening systems the dahlgren systems seemed to show its weaknesses. one weakness that i remember was that the water form roller fit into the space that used to be occupied by the number 1 ink form. it was a fully intergrated system but the downside was that you sacrificed one of your ink forms. on the plus side i seen to remember that it had the ability to skew and it was an easy setting to make. i think id be more concerened about the actual press that your buying as opposed to the dampening system. although i learned printing on the older roland piggyback presses and am familiar with them inside and out i wouldnt want to go back to running one with all their weaknesses when configured as a multicolor press. Even roland eventually seen the weakness of the design and changed over to a unitized configuration. just my 2cents!!!
