Heidelberg SM 74 Alcolor Water Form Roller New Style (Exchange)

The Heidelberg SM 74 Alcolor Water Form Roller New Style is a precision-recovered exchange roller designed for the Alcolor continuous dampening system on the Heidelberg SM 74 offset printing press. Part number M2.030.080F-1, this is the current New Style version of the SM 74 Alcolor Water Form Roller. As a dampening form roller in the Alcolor system, it contacts the printing plate directly to apply a controlled, even film of fountain solution before inking — making its surface condition and concentricity critical to achieving proper ink-water balance and consistent print quality on the SM 74.

A worn or glazed Alcolor Water Form Roller compromises dampening performance on the SM 74 by delivering uneven moisture to the plate. Symptoms include scumming in areas receiving insufficient dampening, dot gain and ink emulsification in over-dampened areas, and toning that persists despite fountain solution adjustments. Because the water form roller contacts the plate at full press speed on every impression, it wears faster than most other dampening components and should be part of a regular preventive maintenance schedule on the SM 74.

This Heidelberg SM 74 Alcolor Water Form Roller New Style is supplied as an exchange unit. Return your worn core within 30 days to avoid additional charges. All exchange rollers are precision-ground and recovered to OEM specifications, ensuring a drop-in fit with no press modification required.
