M&R’s revolutionary Challenger III D, with groundbreaking Dynamic PrintStroke™, brings a new dimension to automatic textile printing. Dynamic PrintStroke™ provides programmable control over squeegee pressure, print/flood speed, print-stroke length, and print-carriage position and other settings. The squeegee pressure setting can be varied between print strokes, offering unparalleled control over ink deposit. These programmable print parameters—along with Ink Dip™, Ink Dam™, flash-cure, and other print settings—can be named, saved, and stored as a unique print program in M&R’s Job Recall™ storage & retrieval system. Operators can later recall that job for subsequent print runs. For similar but not identical jobs, the operator can save a copy of the job under another name and tweak those settings rather than starting from scratch. Stored jobs can even be sent electronically to other Challenger III D machines, providing large operations and contract printers with unprecedented convenience and control over production.
Challenger III D’s huge standard feature set includes a super-fast, ultra-quiet servo-driven indexer; servo-driven printheads; tool-free calibrated angle adjustments; a large and highly-sophisticated touch-screen controller; and quick-set printhead off-contact (invaluable when printing thick inks or specialty inks like gels and high-density). Squeegee pressure can also be adjusted mechanically should the need arise. M&R’s Automatic Pallet Preheat Mode™ with built-in pallet temperature sensor allows operators to preheat pallets to the desired temperature and track those temperatures throughout the production run. Each printhead includes a touchscreen that provides digital control over squeegee print pressure and squeegee and floodbar speeds. A socket on each printhead makes it easy to position a flash cure unit in any station and make on-the-fly adjustments from the main control panel.
Other features include Printhead Teach Mode™; front and rear micro-registration; tool-free adjustable rear screen holders; print-start/print-finish mode; and M&R’s exclusive patented Revolver Print Program™, which automatically operates individual printheads in programmed sequence and allows multiple flashing without losing a printing position. Challenger III is also compatible with pre-press registration systems like M&R’s Tri-Loc and Double Tri-Loc. With so many features and an unmatched level of flexibility, convenience, and control, Challenger III D is simply the finest automatic carousel textile press ever made.
