We have a Heidelberg Suprasetter 74, owned since 2008, and we've been running the PN plates. Everything ran like a dream. (All things considered) We recently switched to Fuji plates (Processor included) because Heidelberg rates went up very significantly. Ever since we made the switch we have had problems with the Suprasetter 74 picking up the slip sheets between the Fuji plates. Heidelberg has replaced all the suckers and made all possible adjustments. It seems to us that it's probably a 'Humidity' issue. (lack of) The Suprasetter's range for Humidity is a minimum of 40%. We've never been close to that. Most of the time, we're in the 20's, down in the teens in the dead of winter. The slip sheets between the Fuji plates deinately have more 'bulk' or 'body' than the sheets between the PN (Agfa) plates.
The Fuji plates seem to work best, but not as good as the Agfa, when the Humidity is in the 20's. If it drops down below 20, we literally have to remove the slip sheets. However, when it's raining a lot, which is has here in Cincinnati recently, the Humidity jumps into the 30's and the Suprasetter starts acting up again, so bad that we have to remove the slip sheets.
Is there anybody else that is having similar, if not the same issues? What are all the possibilities? I would think the closer we get to 40% Humidity, the better it would run. But, maybe the fluxuations in Humidity are working against us.
