2.5 x 1.3m Flatbed UV LED Industrial Printer

JHF introduces the F3900, a super wide flatbed industrial printer with an optional industrial-grade printhead. It supports multi-layer printing with white ink or varnish, while its variable droplet technology delivers stunning, high-speed prints on a wide range of media.
The F3900 serves diverse applications, including sheet metal processing, architectural ceramics, decorative flooring, packaging paperboard, and more. From custom designs to finished products, it enables fast, efficient industrial production, helping businesses bring projects to market quickly.

Key Features

Visual Positioning Feature 


Say goodbye to complicated operations with one-click matching for high-efficiency production. Materials can be placed randomly while the printer automatically identifies the correct printing positions. This feature makes batch printing faster and more efficient, and it’s compatible with a wide variety of materials, effectively doubling production efficiency.

 Tri-Negative Pressure Controlling System


The F3900 uses a dedicated negative pressure system for white ink, color ink, and varnish, ensuring smooth ink flow for each channel. This prevents clogging and sediment buildup, extending the lifespan of the printhead.

Flexible Print Configurations


The F3900 allows flexible configuration of white ink and varnish layers according to your needs, delivering excellent adhesion, abrasion resistance, and high brightness for superior print quality.

Reduced Compressed Air Usage by 90%


 Its negative pressure control system reduces compressed air consumption by over 90%, significantly improving the lifespan of the air compressor and enhancing overall energy efficiency.

Separate Vacuum Absorption Table


The F3900 features a vacuum table with six independent absorption zones, each of which can be controlled individually based on substrate size. This not only ensures secure material hold but also reduces energy consumption.

Core Technology

Multi-Layer Printing
White ink and varnish can be printed simultaneously in multiple layers. The system currently supports up to five-layer printing, enabling rich textures and enhanced visual effects.

Unique Sub-Tank Control Technology

This technology prevents ink leakage in the event of a sudden power outage, ensuring clean operation and protecting critical components.

Automatic Height Adjustment

A fully automated carriage lifting system, combined with a customized motor, ensures precise height control across the entire bed. This allows accurate printing on substrates of varying thicknesses at any position on the table.

Anti-Collision Protection System

The carriage is equipped with anti-collision sensors that detect obstacles on the vacuum table. When an obstruction is detected, the printer immediately stops carriage movement to prevent printhead damage and ensure operator safety.

High-Precision Stepping and Positioning

Dual servo motors on the Y-axis and a linear motor drive on the X-axis enable precise movement control. This system detects and corrects front-to-rear misalignment, significantly improving stepping accuracy and overall table precision.
