Grando Konica 512i Four Head Solvent Flex Printing Machine with UMC Board

To dominate the high-volume outdoor advertising market, print service providers require a production workhorse that bridges the gap between blistering output speeds and long-term mechanical reliability. The key to maximizing profitability in large-format printing lies in minimizing downtime while delivering vibrant, weather-resistant prints that command attention from a distance. Designed specifically to meet these rigorous industrial demands, this heavy-duty solvent platform delivers the uncompromising throughput and continuous uptime necessary to secure high-margin fleet graphics, massive highway billboards, and building wraps on tight turnarounds.

Advanced Industrial Performance

The Grando Konica 512i Four Head Solvent Flex Printing Machine is engineered around a ultra-stable, heavy-duty industrial chassis designed to eliminate frame vibration, even during high-speed carriage cycles. At the heart of its performance are four industrial-grade Konica Minolta 512i (30pl) printheads, renowned for their robust architecture and consistent firing frequency. Driven by a state-of-the-art UMC (Ultra-precision Main Board Control) board, the system ensures seamless data transmission, ultra-low latency, and precise firing synchronization across all 2048 active nozzles. This advanced hardware integration allows print shops to achieve exceptional production speeds exceeding 120 square meters per hour in high-speed draft modes, without sacrificing step accuracy or band alignment. The mechanical stability is further reinforced by a high-precision linear guide rail and a dual AC servo motor system, ensuring smooth, whisper-quiet carriage movement. This rugged engineering ensures that the machine can run 24/7 continuous shifts, maintaining razor-sharp text and solid color fills over thousands of linear meters of media.

Core Technology & Media Handling

Engineered for high-capacity roll-to-roll media handling, this solvent printer features an advanced, tension-controlled automatic feeding and take-up system capable of managing heavy, full-width 3.2-meter flex rolls. To facilitate rapid ink drying and prevent media sticking or blocking during high-speed rewinding, the machine is equipped with an intelligent multi-stage heating and drying system:

• Pre-Heater: Conditions the media surface, opening pores to accept the solvent ink for superior adhesion.
• Platform Heater: Controls ink dot gain and spread at the moment of impact, ensuring sharp detail and rich color saturation.
• Post-Heater & Infrared Drying System: Instantly cures the solvent ink carrier before the media reaches the take-up reel, preventing ink offsetting and smudging.
• Negative Pressure System: Maintains consistent ink flow to the Konica 512i heads, preventing ink starvation during continuous high-speed printing.

Compatible Media & Profitable Applications

The high-density solvent ink chemistry combined with the robust media handling system allows print businesses to target a wide variety of profitable outdoor and indoor applications. Compatible media types include:

• Frontlit & Backlit Flex Banners: Perfect for durable outdoor billboards, trade show displays, and illuminated airport signage.
• Self-Adhesive Vinyl & PVC Films: Ideal for vehicle wraps, fleet graphics, and high-impact outdoor promotional decals.
• One-Way Vision & Mesh: Used for building wraps and window graphics where wind permeability or light transmission is required.
• Solvent Blueback Paper & Canvas: Excellent for high-volume billboard posters, fine art reproductions, and durable indoor wall coverings.

RIP Software & Color Management

To fully harness the capabilities of the Konica 512i printheads and the UMC board, the system supports industry-standard RIP software platforms including MainTop, PhotoPrint (FlexiSign), and UltraPrint. The standard CMYK 4-color configuration is optimized for maximum ink density and wide color gamut performance. Through the RIP software, operators can access advanced ICC profiling tools to calibrate color output based on specific media brands, ensuring consistent brand-color matching across multi-panel billboard runs. The UMC board’s proprietary dithering algorithms work in tandem with the RIP software to eliminate banding, smooth out gradients, and optimize ink consumption, saving valuable resources on high-volume print runs.

Maintenance & Operational Safety

Preserving the lifespan of industrial printheads and maintaining a safe workshop environment are critical for sustainable profitability. This machine incorporates a series of automated maintenance tools and safety features designed to protect your investment and your operators:

• Positive Pressure Purging System: Allows operators to clear individual color channels with a single button press, minimizing ink waste during daily startup.
• Manual/Automatic Printhead Capping & Wiping Station: Prevents solvent ink from drying on the nozzle plate during idle periods, reducing the risk of nozzle deflection.
• Anti-Collision Carriage Sensors: Instantly pauses print operations if an obstruction or media wrinkle is detected, protecting the expensive Konica 512i printheads from mechanical damage.
• Dual Emergency Stop Switches: Positioned on both sides of the machine frame for immediate power cut-off in unsafe conditions.
• Integrated Fume Extraction Interface: Facilitates the connection of external ventilation systems to safely exhaust solvent VOCs from the print room.
