III. Five Key Product Advantages

1. Superior Printing Quality

   
   

   Ultra-fine 1.5pl ink droplets deliver smooth grain-free fine texts and color gradients; large 21pl droplets achieve solid full-color filling without ink show-through. Perfect for vehicle wraps, high-definition backlit films and window decals with accurate color reproduction.
2. Clog-resistant & Durable for Solvent Inks

   
   

   Adopting original Epson Micro Piezo technology with excellent corrosion resistance. Compatible with most domestic and genuine branded mild solvent inks on the market. Less prone to nozzle missing and directional ink deviation compared with aftermarket modified printheads, ensuring stable long-run continuous production.
3. Dual-mode Compatibility for 4-color / 8-color Configurations

   
   

   8-channel design supports standard CMYK 4-color setup or upgraded 8-color printing with light cyan & light magenta for premium high-definition output without replacing the printhead.
4. High-speed Mass Production & High Productivity

   
   

   8KHz high-frequency ink ejection enables faster feed speed at identical print resolution, greatly boosting mass production efficiency of vehicle stickers and banners for sign factories.
5. Wide Compatibility & Low Replacement Cost

   
   

   Unified part number across all VS/RA/RF/BN20 series for easy inventory management. Mature global supply chain allows convenient aftermarket replacement; it is the most widely used classic printhead for Roland devices.
