"?No-Mark' Anti-Tracking Starwheels feature modular components that make it easier for press operators of all skill levels to produce top quality work on high gloss stocks without ink marking or tracking. The standard "?No-Mark' set includes TEFCLEAN components that can be moved to any point on the wheel's circumference. This allows infinite positioning to the copy. The proprietary TEFCLEAN material effectively repels all oil- and rubber-based inks. In addition the wheels are also outfitted with free-spinning, soft, natural bristle BRUSH Wheels. The brush wheel option is very effective on difficult to print heavy solids and jobs with large halftone coverage. "?No-Mark' Starwheels are available for all press sizes.
