Detailed Explanation of UV Cylindrical Printers Using Ricoh Nozzles
UV cylindrical printers are specialized devices designed for high-precision printing on the surfaces of cylindrical or curved objects, such as bottles, cups, metal tubes, cosmetic containers, etc. UV cylindrical printers equipped with Ricoh series nozzles have occupied an important position in the industrial printing field due to their high precision, high speed and stability.
The core advantages of Ricoh nozzles
The application of Ricoh nozzles (such as Ricoh Gen 5, Gen 6, etc.) in UV cylindrical printers mainly relies on the following technical advantages:
- High resolution & high precision
Minimum ink droplet size: 3.5-7 picoliters, capable of achieving an ultra-high resolution of 1440dpi to 1600dpi, suitable for fine patterns and gradient colors.
Variable droplet Technology (VSD) : It can dynamically adjust the droplet size (such as 3.5pl/7pl/14pl), optimizing the printing speed and accuracy.
- High printing speed
Multi-level grayscale printing (8 to 16 levels of grayscale), reducing the number of passes (the number of layers in a single print), and improving production efficiency.
The maximum spray frequency can reach 50kHz to 100kHz, and the printing speed of industrial-grade models can reach 30 to 60 meters per minute (depending on the material).
- Stability and durability
Industrial-grade nozzle design, supporting 24/7 continuous production, with a long service life (usually 2 to 3 years).
Resistant to UV ink corrosion, suitable for UV curing ink, and not prone to clogging.
- Multi-color printing capability
Supports CMYK+ white ink + varnish (6-color or 8-color configuration), achieving high color gamut and special effects (such as 3D embossing, local varnish).
2. Applicable materials and application fields
- Applicable materials
Plastics: PET bottles, PVC pipes, cosmetic bottles, toys, etc.
Glass: wine bottles, perfume bottles, glass cups, etc.
Metals: aluminum cans, thermos cups, metal pipes, etc.
Ceramics: mugs, tiles, handicrafts, etc.
- Main application industries
Packaging and printing: Personalized customization for beverage bottles, cosmetic packaging, medicine tubes, etc.
Home decoration: cylindrical vases, lampshades, pen holders, etc.
Industrial parts: metal pipe marking, electronic component printing, etc.
Promotional gifts: Customized water cups, souvenirs and other small-batch production.
3. Maintenance and optimization suggestions
Nozzle maintenance: Daily automatic cleaning to prevent UV ink from curing and clogging.
Environmental control: Maintain a constant temperature (20-28℃) and humidity of 40% – 60%.
Ink selection: Use original or certified UV ink to avoid damage to the nozzle from inferior ink.
Regular calibration: Adjust the nozzle height and ink drop point through software to ensure printing accuracy.
