Ran into something last night I've never seen before. Running a large magazine on our Sunday 2000 (177,000 run) and after about 25,000 impressions I am getting a pretty solid ink build up on the yellow unit. It's happening both top and bottom. Took the plates off and I was shocked to see about a 2mm thick build up. It is definitely effecting print quality and happening on both top and bottom.
Was down for about two hours troubleshooting - checked conductivity, pH, temperature of fountain solution, temp of water in the pan, plate temp, blanket temp, roller temps, settings of rollers all correct. All normal in the unit!
Checked with Prepress and nothing changed there...
Just switched over ink and am draining the pipes now (ink totes are about 100 feet away from the press). Could be bad ink??
Anyone see anything like this before?
