Water Roller Compounds

Dampening Rollers

ESQ Series: This European designed compound will combat the inherent problems associated with glycol based alcohol substitutes. Keeping the lead edge of the sheet clean from ink is problematic and requires a roller that will not allow this phenomenon, and the impact it imparts on the Pan roller. Most rollers are susceptible to end swell as a direct result and in a loss of control of water typically 2 to 3 inches in from the ends of the roller. Rollers with crowns are specifically vulnerable to this phenomenon.
The use of the ESQ-P in combination with ESQ-F provides an evenly distributed film of solution at an optimal level over the entire sheet, specifically when running with full coverage.
Durometers are 25 & 38 shore A.

WGR Series: This compound allows an operator to control a fine film of water throughout the sheet providing greater control. It is very helpful in the wide format commercial web environment where water can gather in the non-image areas on a wide sheet. Most rollers are susceptible to end swell that result in a loss of control of water typically 2 to 3 inches in from the ends of the roller. Durometer ranges from 25 to 30 shore A.

Trust Lambda: A perfect complement to the Trust Delta roller, this resin based compound has excellent hydrophilic qualities, less swelling and shrinkage, and designed for continuous dampening systems. Durometer ranges from 20 to 50 shore A.

Ryno Hydrometric: Like the Ryno inking roller, this resin based compound has a soft touch and feel to a roller, which results in more control of the water as it travels through the nip. It is very hydrophilic resulting in less surface tension of the water bead, which ultimately promotes more accurate metering of the fountain solution. Durometer ranges from 20 to 40 shore A.

HF Series: This carbon filled hydrophilic rubber is designed to improve wetting with continuous dampening systems. The compound promotes more water transfer, which will permit slower speeds of the metering roller and better control of the fountain solution through the nip. Durometer ranges from 25 to 30 shore A.
