Why 6090 Is the Starting Format for Direct-to-Substrate Printing
UV flatbed sizes run from A3 through 6090 up to 2513 (2.5 x 1.3 m). For most custom factories, 60 x 90 cm is the most balanced starting point: it covers the bread-and-butter orders — acrylic pieces, medals, phone cases, small plates — while keeping footprint and investment far below large-format machines.
Fix the Material Before the Machine
A UV flatbed handles rigid flat parts, and the material drives the process:
| Material | Printing notes | Pre-treatment |
|---|---|---|
| Acrylic | Medium surface energy, good adhesion, front or reverse printing | Clean and de-staticise |
| Glass | Dense surface, adhesion is the hard part | Clean plus primer |
| Wood / MDF | Uneven absorption and grain, white base layer helps | Sand and de-dust |
| Metal plates | High demands on adhesion and scratch resistance | Clean plus primer |
| Leather | Soft and elastic, must be flattened and fixed | Clean, treatment agent if needed |
Thickness matters just as much: the FLY-6090U table adjusts 0-180 mm, covering standard boards and finished parts, while thicker irregular parts need a custom jig.
Choosing the Head: XP600 / TX800 / I1600 / I3200
The head sets speed, precision and machine price. Get it wrong and you either lack capacity or waste budget:
- XP600 — entry level, right for sampling and small batches.
- TX800 — the value step up, noticeably faster once order volume grows.
- I1600 — balance of speed and precision, the mainstream choice for factories.
- I3200 — high-speed production for continuous runs and tight deadlines.
Note that white ink and varnish occupy channels and relief mode slows output — leave headroom when specifying.
Relief, White Ink and Varnish: Do You Need Them?
Relief is where a UV flatbed earns its margin. White ink is stacked in the same area to build height, then colour and varnish go on top — the tactile result commands a higher unit price and suits gifts, medals and premium plates. The cost is a white channel and lower speed. If your orders are mostly flat graphics, start without relief and add it once volume is proven.
Pre-treatment and Adhesion: Where Projects Go Wrong
Whether cured UV ink peels depends on the material's surface energy, not the machine. Glass and metal need cleaning plus a primer; before mass production, confirm colour, adhesion and abrasion resistance on a physical sample. Skip this and everything downstream turns into rework.
Where the Price Band Sits
Price moves with head configuration and whether a white-ink and varnish set is included — it is not a flat function of format. The simple test is to work backwards from daily output: under 50 pieces a day, entry configuration; 50-200 pieces, mainstream; above 200 pieces, high-speed production.

Five Questions
Can a UV flatbed replace UV DTF (crystal label) printing?
No. A flatbed prints rigid flat parts directly and the part is ready to use; UV DTF prints onto film for transfer and solves curved and irregular surfaces. They complement each other — many factories run both.
How large a job can the 6090 take?
Any single part within 60 x 90 cm. Larger images can be tiled, but seams risk colour shift; above 1.2 m consider a large-format machine.
Does white ink need daily use?
White ink is pigment-based and settles, so heads clog if idle. Run a nozzle check and a short print daily; follow the maintenance routine if idle more than three days.
Does relief delay delivery?
Yes. Relief mode is noticeably slower — quote it and schedule it as a separate process step.
Can soft materials like leather go on the 6090?
Yes, but they must be flattened and fixed. For rolled and soft materials in volume, a belt printer is the better tool — wider format, steadier feeding.
