Cushion Support

The original microcellular urethane cushion support system

Cushion Support, R/bak by Rogers

R/bak is the original microcellular urethane cushion system, engineered to improve print quality, extend plate life, and support faster press speeds. Its open-cell structure offers excellent energy absorption and resilience, acting as a shock absorber to reduce pressure between the flexographic plate and substrate. This helps enhance registration, minimise dot gain, and improve ink transfer – all while supporting finer detail in print.

Durable and consistent, R/bak resists cell breakdown and cushion fatigue for long-term reliability. The standard version for corrugated flexo is blue with a polyester backing, reference code ‘SF’.
