SPECIFICATIONS

Key Features & Capabilities

Here is a more granular look at what each component of the specification implies, and what you should expect or verify when purchasing.

1. “A1 6090” / “6090 UV” Nomenclature

• Print size / bed dimensions: The “6090” generally means a 600 × 900 mm (i.e. about 23.6″ × 35.4″) maximum printable area. 

• Media thickness / height clearance: Many 6090 models allow printing on substrates up to roughly 150–180 mm (or sometimes up to ~200 mm) thickness. 

• “A1” designation: Implies a “large-format / wide” flatbed size roughly in the realm of A1 (though a true A1 is 594 × 841 mm), so the nomenclature is a marketing alignment.

2. Print Heads – Epson “3PC XP600” + Alternatives

• Many of these UV 6090 machines come with 3 Epson XP600 print heads (often custom‑modified or adapted for UV inks) to provide multiple color channels. 

• Some versions use TX800 or other types (or hybrid combinations) for better durability or different performance. 

• The “3PC” means three print heads, allowing different channel allocations (e.g. CMYK + W + V or distributing light colors).

• The XP600 is a “variable-drop, piezoelectric” head; when used for UV, special handling (ink viscosity, heating, maintenance) is needed.

• Print resolution capability is often advertised in the range of 720 × 2880 dpi (or similar) depending on pass mode and RIP software. 

3. Color Channels: CMYKW + LC + LM + Varnish

• CMYKW: Cyan, Magenta, Yellow, Black, White

• LC + LM: Light Cyan, Light Magenta (to smooth gradients, reduce banding, improve color transitions)

• V (Varnish or Gloss / Clear Coat): Used for protective coating or spot-UV / gloss effects

• In sum, this gives up to 9 (or more) channels or “inks” that can be driven separately for advanced printing.

• The machine often has a “closed / recirculation / negative pressure” ink system for white ink to prevent settling or clogging. 

• The varnish channel is sometimes used in the same pass (if head configuration allows) or in a separate pass for spot gloss effects. 

4. Flatbed + Automatic Operation

• Flatbed / vacuum bed: A stationary printing platform that holds rigid media (glass, acrylic, metal, wood, plastic, etc.) via vacuum suction or similar means. 

• Automatic / semi-automatic operation: The machine may have features like automatic height detection, automatic head cleaning / capping, blank-spot skipping, and auto head protection (spray flushing) when idle. 

• Servo / linear rail systems: For precise movement in X/Y axes and stability. 

• Ink management: Intelligent ink volume control, refilling “on the fly,” and ink level tracking are often integrated. 

5. Rotary Axis

• A rotary axis option enables printing on cylindrical or round objects (e.g. bottles, tubes, pens).

• The machine would either have a built‑in rotary attachment or an add-on module to clamp and rotate cylindrical media under the print head.

• This expands the machine’s versatility beyond flat objects to curved shapes.

6. Curing & UV System

• LED UV lamps: The curing system is typically LED-based, with water-cooling or air + water cooling to maintain temperature stability and LED longevity. 

• Power / life: The UV lamp power is often in the tens of watts (e.g. 50 W or more), and promised life spans of LEDs may be 20,000–50,000 hours depending on cooling design. 

• Because UV curing is instantaneous, prints typically come out dry and ready immediately after printing (no drying time). 

7. Performance & Throughput

• Print speed / pass modes: Speeds depend on pass mode (higher passes → better quality but slower). Some published speeds:

  • 8-pass mode: ~30 s per A3 (on smaller machines) 

  • 4-pass: ~3–10 m²/h (varies widely) 

  • 6-pass, 8-pass, 10-pass variants for different quality levels 

• Ink consumption: Often around 10 ml per m² (for CMYK or normal color coverage) in many listings. 

• Resolution: Up to 2880 × 720 dpi in many models; in high-quality modes effective resolution is often lower (but visually good). 

8. Mechanical / Structural / Environmental Specs

• Framework & motion: Linear guides, servo motors, stable aluminum or steel gantries to reduce vibration and ensure registration.

• Height adjustment: Motorized or semi-automatic Z-axis adjustment for different substrate thicknesses.

• Weight / dimensions: Often quite heavy (100–300+ kg) depending on frame and accessories. 

• Voltage / power: Many machines support 110V / 220V (50/60 Hz) input. 

• Working environment: Typical operating temperature ~20‑35 °C, humidity ~35‑80% RH. 

• Cooling / ventilation: UV lamp cooling, print head cooling, exhaust to vent ozone, if any (depending on lamp type).

9. Software / RIP / Controls

• RIP software: Commonly supports Photoprint, Maintop, Onyx, etc. 

• File formats: TIFF, PNG, JPG, PDF, EPS, etc. 

• Operating system: Usually Windows-based control (Windows 7/10). 

• Connectivity: Ethernet / LAN, USB, sometimes gigabit networking. 

10. Strengths

• Versatility: Can print on nearly any flat rigid substrate (glass, acrylic, metal, wood, plastic, ceramic, leather, etc.). 

• Instant curing: No post-drying needed, minimal smudging, immediate handling.

• Multi-channel capabilities: White, light colors, varnish, etc., allow advanced effects (spot varnish, emboss, raised printing).

• One-pass or few-pass printing (in many cases) increases throughput.
