Didde Web Press Roller 795-750

The Didde Web Press Roller 795-750 is a precision-recovered Dahlgren Form Roller designed for use on Didde web offset printing presses equipped with the Dahlgren dampening system. Part number 329-750, this roller also matches Lith-O-Roll part number DG-175-15-D. As a dampening form roller in the Dahlgren system, the 795-750 contacts the printing plate directly to apply a precisely controlled film of fountain solution before each impression — making its surface condition, durometer, and concentricity critical to achieving clean, even dampening and proper ink-water balance across the full web width on your Didde press.

Dahlgren form rollers are high-wear components because they contact the plate at press speed on every impression cycle. Over time, the roller surface glazes, hardens, and loses its ability to uniformly transfer fountain solution to the plate. A worn Dahlgren form roller causes uneven dampening, leading to scumming in dry areas, ink emulsification in over-dampened areas, inconsistent dot reproduction, and toning — all of which waste paper and slow production. Replacing the worn 795-750 with a precision-recovered unit restores uniform moisture application to the plate and brings Dahlgren dampening performance back to OEM standard.

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 Dahlgren form roller for your specific press.
