With high-frequency firing capability and a robust internal structure, the CF3 printhead delivers outstanding performance in high-resolution image printing and industrial applications. It is an ideal choice for users who demand reliability and high-resolution output.
Technical Specs
Key Advantages
High-Resolution Output
In single-color mode, resolution reaches up to 600 npi; in dual-color mode, 300 npi. This meets the high-precision requirements of industrial printing for text sharpness, fine graphics, and detailed patterns.
Flexible Drop Size
Supports 3 pL–28 pL variable drop printing. From ultra-fine details to large area coverage, it can deliver both high-definition images and vivid color expression, ensuring broad print adaptability.
Advanced Ink Recirculation
Full-channel ink recirculation minimizes sedimentation and clogging, particularly suitable for UV white ink, which is prone to settling. It ensures consistent ink supply and stable long-term operation.
High Firing Frequency
With a maximum firing frequency of 28 kHz (2 gray levels), it enables faster printing speeds and maintains stable output even during long production runs.
Wide Ink Compatibility
Compatible with both UV-curable and oil-based inks, providing flexibility for diverse applications.
Compact and Durable Design
The printhead features a robust and durable structure with integrated stable drive voltage control, ensuring long-term reliable operation in industrial environments.
Limitations
Cooling Method
The CF3 uses air cooling. Compared to the CF3R (which uses water cooling), it has lower heat dissipation efficiency during long continuous runs.
Ink Sensitivity
More prone to ink sedimentation and clogging compared to CF3R, especially with heavy-particle inks like UV white.
Maintenance Requirements
Requires regular cleaning and maintenance to prevent clogging and extend lifespan.
Application Scope
Packaging Printing: Paper boxes, corrugated cardboard, cartons.
Labels & Tags: Non-adhesive labels, PVC, thin films.
Building & Decoration Materials: Glass, ceramics, wood, acrylic, etc.
Industrial Coding & Large-Format UV Flatbed Printers.
Usage Recommendations
Use high-quality UV-curable or oil-based inks to ensure print quality and extend service life.
Maintain smooth ink passage and avoid air leakage to prevent clogging.
Ensure the working environment is stable in temperature and humidity.
Regularly check the printhead’s condition, clean when necessary, and prolong usage with timely maintenance.
Product Dimensions
Comparison with CF3R
1. Resolution and Jetting Performance
The CF3 offers a single-color printing resolution of up to 600 npi and 300 npi in dual-color mode, supporting 6 grayscale levels with a drop size range of 3–28 pL. The CF3R maintains these same specifications but provides improved ignition control and droplet stability, ensuring more consistent output during long periods of high-speed operation.
2. Ink Recirculation and Compatibility
The CF3 is equipped with full-channel ink recirculation, effectively reducing sedimentation and clogging, and is compatible with both UV-curable and oil-based inks. Building on this, the CF3R features an optimized ink path design, offering stronger adaptability to high-viscosity or sediment-prone UV inks, resulting in more stable performance.
3. Cooling Method
CF3: Air cooling, dependent on external environment, less effective for long runs.
CF3R: Water cooling, superior heat dissipation, ideal for long-duration industrial printing.
4. Application Scenario Differences
The CF3 is more suitable for general packaging printing, labels, stickers, and signage applications, focusing on cost-effectiveness.
The CF3R is better suited for high-end UV flatbed printers and enterprises requiring long-term high-speed production, especially industrial users that need to work with high-viscosity UV inks.
Conclusion
The CF3 offers strong standard performance and cost-effectiveness, suitable for regular UV and oil-based ink applications.
The CF3R, as an upgraded version, provides enhanced water-cooling efficiency and an optimized recirculation system, making it better suited for high-speed and high-stability industrial production.
