Description

The Copperhead Speedmaster OS Automatic Screenprinting Press is an industrial, large-format automatic screen printing press engineered for high-volume oversized and all-over apparel printing. Operating at speeds up to 960 pieces per hour, the Speedmaster OS extends the high-speed Speedmaster platform with wider pallet arms, a centralized pallet locating system, and a smart pallet load calculator to protect the drive motor during heavy-duty shifts. Featuring a massive 28 x 40 inch print area, servo-driven chain indexing with pneumatic tensioning, and a Squeegee Pressure Equalizer System, this press handles continuous large-scale graphics without losing registration accuracy.

The LWG Difference

  • Smart Pallet Load Calculator: Intelligently calculates payload weight and optimizes indexing torque to protect the motor while maintaining maximum speed during long production shifts.
  • Centralized Pallet Locating System: Ensures exact registration accuracy across large-format platen setups and complex all-over print designs.
  • Heat-Dampening Wide Pallet Arms: Extended pallet support arms paired with rubber-coated aluminum platens evenly distribute squeegee force while reducing heat retention from flash curing.
  • Dedicated American Factory Support: Fully distributed and supported by Lawson Screen & Digital Products, offering factory installation, technical assistance, and direct replacement parts.

Features

  • High-Output Speedmaster Platform: Delivers fast cycle times capable of outputting up to 960 garments per hour.
  • Oversized Print Capacity: Standard image area of 28 x 40 inches (71 x 102 cm) designed specifically for all-over, jumbo, and specialty textile prints.
  • Servo-Driven Chain Indexing: Smooth servo indexing with pneumatic chain tensioning ensures precise, low-vibration rotation.
  • Squeegee Pressure Equalizer System: Patented equalizer balances squeegee pressure automatically across the screen for consistent ink deposit.
  • Digital Touchscreen Control Panel: Icon-based digital HMI provides intuitive job setups, self-diagnostics, and real-time production tracking.
  • Tool-Free Setup Controls: Rapid, tool-free adjustments for off-contact height, print stroke length, and squeegee/floodbar stroke angles.
