Challenger® II and Challenger® II OS are M&R’s most affordable large-format high-performance automatic screen printing presses. Designed for quick setups and high-speed production, they’re loaded with timesaving, output-enhancing features, making them outstanding performers in any screen printing shop. Challenger II is available in 10, 12, 14, 16, and 18-color models with a 50 x 70 cm (20” x 28”) maximum image area. Challenger II OS is available in 8, 10, and 12-color models with an oversize 70 x 100 cm (28” x 39”) maximum image area, and all Challenger II OS models feature large, heavy-duty pallet support arms and oversize pallet leveling brackets for exceptional rigidity and stability on cut-piece printing. All Challenger II automatic screen printing machines feature servo-driven indexers, electric printheads, and multiple print-stroke capability.

Challenger II and Challenger II OS presses are compatible with most screen registration systems, including M&R’s Tri-Loc® and Double Tri-Loc®. Standard pneumatic screen clamps hold frames tight and allow rapid screen loading. Standard features include independent squeegee & floodbar speed adjustments; adjustable rear screen holders; and independently-set and calibrated squeegee and floodbar angles. Calibrated pressure adjustments offer the ultimate in control. Independent print, reset, and print/flood speed controls on each printhead make setup easy. Challenger II/II OS screen printing presses include user-friendly LCD touchscreen control panels with extensive onboard self-diagnostics, real-time production data, and easy print parameter adjustment. The independent print-start/print-finish setting saves time by automatically activating and stopping printheads at the beginning and end of production runs.

The tool-free pallet locator system, quick release pallet locks, digital squeegee/floodbar speed display, and enhanced front micro-registration adjustments simplify press operation, and central off-contact permits fast adjustment of all stations simultaneously. M&R’s Revolver Print Program™ automatically operates individual printheads in programmed sequence and allows multiple flashing without losing a printing position. M&R’s Transformer Printheads give standard Challenger II 12, 14, 16, and 18-color screen printing machines a 100 cm (39”) print stroke without increasing press diameter. For example, Transformer Printheads enable the standard Challenger II press to print oversize and all-over images up to 94 x 99 cm (37” x 39”) on alternating printheads. Challenger II and Challenger II OS options include M&R’s Optical No-Shirt Detector, which minimizes the misprints and press stoppage that result from improper T-shirt loading. Ruggedly built and loaded with features, Challenger II and Challenger II OS are M&R’s most affordable high-production automatic screen printing presses.
