Didde Web Press Roller 329-726

The Didde Web Press Roller 329-726 is a precision-recovered Water Meter Roller for the Quadflow dampening system on the Didde ML1000, Didde 860, and Didde Model 20.5″ web offset printing presses. Part number 329-726, this roller also matches Lith-O-Roll part number DG-329-14. As the water meter roller in the Quadflow dampening circuit, the 329-726 controls the metered transfer of fountain solution from the pan roller through the dampening train — regulating how much moisture reaches the printing plate. Precise metering at this stage is essential for maintaining stable ink-water balance and consistent dampening performance on your Didde press.

A worn or glazed Quadflow water meter roller causes the dampening system to lose accurate control over fountain solution delivery, resulting in either over-dampening or under-dampening at the plate. Over-dampening leads to ink emulsification and dot gain; under-dampening causes scumming and toning. Both conditions waste paper, increase makeready time, and reduce print quality. Replacing the worn 329-726 with a precision-recovered water meter roller restores accurate dampening control, stabilizes ink-water balance, and improves consistency across the entire press run.

Please verify the part number prior to ordering — many Didde models share rollers that may be interchangeable across configurations, and confirming the correct part number ensures you receive the right water meter roller for your specific press.
