WitColor 1702S Epson I3200-U1 Dual Head UV Roll to Roll Printer

To capture the most lucrative segments of the modern signage and interior decor markets, print service providers must deliver flawless, instantly cured prints on a vast array of flexible substrates. The ability to bypass traditional outgassing times and transition prints directly from the take-up reel to the installation site is what separates high-capacity operations from their competitors. By integrating advanced ultraviolet curing technology with an ultra-stable industrial chassis, businesses can unlock premium, high-margin applications such as double-sided backlit displays, textured wallcoverings, and customized eco-leather goods.

The Wit Color 1702 S Epson I3200-U1 Dual Head UV Roll to Roll Printer is engineered to meet this exact demand. It bridges the gap between high-speed industrial throughput and ultra-fine photographic output, ensuring your print shop can scale production without sacrificing the micro-text and vibrant color transitions that demanding corporate clients expect.

Advanced Industrial Performance

The Wit Color 1702 S is built upon a heavy-duty, CNC-machined industrial steel frame designed to eliminate structural micro-vibrations during high-speed carriage movement. This rigid chassis stability is critical for maintaining mechanical registration over long production runs. Equipped with dual Epson I3200-U1 PrecisionCore printheads in a staggered configuration, the printer delivers physical resolution up to 3200 DPI. The system utilizes an industrial-grade linear guide rail and a high-performance Panasonic AC servo motor drive system, enabling smooth, whisper-quiet carriage movement even at peak velocities.

With its dual-head architecture, the Wit Color 1702 S achieves highly competitive production speeds, delivering up to 18 to 25 square meters per hour in production modes. The printhead carriage features integrated anti-collision sensors on both sides to protect the delicate micro-piezo nozzles from head strikes caused by media ripples. This mechanical resilience ensures uninterrupted operation during overnight shifts, maximizing daily output while minimizing material waste and downtime.

Core Technology & Media Handling

At the heart of the Wit Color 1702 S is a sophisticated 1.7-meter roll-to-roll media handling system. It features an advanced, tension-controlled feeding and take-up system that dynamically adjusts torque based on the roll weight. This prevents stretching, skewing, or wrinkling of sensitive materials like thin backlit films or heavy canvas. A multi-zone vacuum bed with adjustable suction power keeps the media perfectly flat against the printing platen, ensuring a consistent head-to-media gap across the entire 1700mm printing width.

Curing is handled by dual, high-intensity UV LED lamps equipped with an intelligent water-cooling loop. Unlike air-cooled alternatives, this water-cooling system maintains a consistent, low operating temperature, preventing heat-sensitive films from warping or buckling under the lamps. The UV LED units feature adjustable power levels, allowing operators to calibrate the curing intensity precisely to the media type and ink thickness, ensuring complete polymerization and excellent adhesion without over-curing.

Compatible Media & Profitable Applications

The versatility of the Wit Color 1702 S allows print shops to diversify their product portfolios and target high-value commercial contracts. The low-heat UV LED curing system makes it compatible with an expansive range of flexible substrates, including:

• Premium Backlit Films (PET): Perfect for high-impact airport lightboxes and retail window displays.
• Self-Adhesive Vinyl & Window Graphics: Ideal for vehicle wraps, architectural glass decals, and promotional floor graphics.
• Canvas & Fine Art Media: Enables high-end reproduction prints with rich, textured finishes.
• Custom Wallpaper & Wallcoverings: Unlocks profitable interior design projects using textured, odorless UV inks.
• Specialty Substrates: Including soft ceiling films, TPU films, synthetic leather, and non-woven fabrics.

RIP Software & Color Management

Achieving color accuracy and smooth gradients requires seamless integration between hardware and software. The Wit Color 1702 S supports industry-standard RIP platforms, including PhotoPrint (Flexi), Maintop, and Onyx. These software solutions provide advanced ICC profile management, spot color replacement, and nesting tools to minimize media waste. The printer is configured for a versatile ink delivery system supporting CMYK plus White (CMYK+W) or CMYK plus White and Varnish (CMYK+W+V) configurations.

The inclusion of dedicated white ink channels allows for three-layer printing (Color-White-Color) in a single pass, which is essential for creating stunning double-sided graphics on transparent window films. A continuous white ink circulation system prevents pigment sedimentation, ensuring consistent density and preventing nozzle clogging. This advanced color management setup ensures that corporate brand colors are reproduced accurately across different media types, from matte canvas to gloss vinyl.

Maintenance & Operational Safety

To protect your investment and maintain consistent print quality, the Wit Color 1702 S incorporates several automated maintenance and safety systems designed for busy production environments:

• Automated Printhead Capping & Wiping Station: Keeps the Epson I3200-U1 nozzles moist and sealed when idle, preventing ink drying and minimizing manual cleaning cycles.
• Active Negative Pressure System: Maintains optimal ink pressure within the printheads, preventing ink dripping and ensuring stable ink delivery during high-speed printing.
• White Ink Agitation & Circulation: Automatically circulates white ink from the main tank to the sub-tank to eliminate pigment settling and maintain opacity.
• Dual Emergency Stop Buttons: Positioned on both ends of the printer for immediate operator intervention during mechanical faults.
• Carriage Anti-Collision System: Instantly pauses the print job if the sensor detects any lifting or obstruction on the media bed, protecting the printheads from physical damage.
• UV Light Shielding: Specially designed physical guards around the UV LED lamps protect operators from direct UV exposure during operation.
