Exchange Roller – Return core within 30 days to avoid additional charges.

The Alcolor Pan Roller is designed for the Heidelberg SM74. It is composed of a splash pan, an ink roller and a dampening roller. It is used to apply fountain solution onto the blanket cylinder of offset printing machines.

The Alcolor Pan Roller assembly on the SM 74 includes a splash pan, ink roller, and dampening roller that work in concert to deliver a continuous, metered film of fountain solution into the Alcolor dampening circuit. Precise performance at the pan roller stage is fundamental to maintaining stable ink-water balance on the SM 74 — any wear or degradation of the pan roller components introduces variability into fountain solution pickup that propagates through the entire dampening system.

A worn SM 74 Alcolor Pan Roller causes dampening problems that often present as scumming, toning, ink emulsification, inconsistent dot gain, and difficulty holding stable ink density during the press run. Because these symptoms overlap with ink, chemistry, and plate issues, a degraded pan roller is often overlooked as the root cause. Replacing a worn M2.030.501 pan roller with a precision-recovered unit frequently resolves persistent dampening problems that have resisted other corrective measures.

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 for a drop-in fit. Contact us for volume pricing and availability.
