The xTool O1 Omni is a 4-in-1 printer: UV direct printing, UV DTF, and DTG/DTF fabric printing, plus advanced effects like gold foiling, 3D texture, and fluorescent ink. Because it does so much, beginners usually get stuck on materials rather than the machine. Which materials do you buy? Which film goes with which workflow? Why does some ink refuse to stick, flake off, curl at the edges, or fail after a few washes?
What this guide does: puts every O1 Omni material, consumable, and accessory in one place, and shows which workflow each one belongs to.
1. Which O1 Omni edition does what: single UV vs dual UV vs UV+DT
Single UV | Dual UV | UV + DT | |
In one line | Direct printing on rigid materials | Advanced effects — two UV heads unlock fluorescent ink and flexible materials | Hard goods plus fabric; one machine, two production lines |
Printhead configuration | One UV head (CMYKWV) | Two UV heads (CMYKWV + RW/FW/FR/FY) | UV head + fabric head (UV: CMYKWV; DT fabric: CMYKW) |
Supported workflows | UV direct printing ✅ | UV direct printing ✅ | UV direct printing ✅ |

Simple to use: find your edition column, read it down, and you'll know what you can buy and what to pair it with.
🌟 Table 1 · What you can print on directly
Material | Single UV | Dual UV | UV + DT | Required consumables | Required accessories | Notes |
✅ | ✅ | ✅ | — | Hanging signs, keychains, display plaques, fridge magnets. | ||
✅ | ✅ | ✅ | — | Nameplates, medals, metal cards. Adhesion varies widely by coating — use a primer matched to it. | ||
✅ | ✅ | ✅ | OR1 Rotary for tumblers | Flat glass prints directly. Use the OR1 for tumbler bodies and cylinders; for complex curves, choose UV DTF. | ||
Ceramic | ✅ | ✅ | ✅ | OR1 Rotary for tumblers | Tiles, ceramic plaques, small ornaments. Avoid drinking rims and food-contact surfaces. | |
Plastic | ✅ | ✅ | ✅ | Matching primer where the material calls for it | — | ABS, PC, and acrylic types work best. Soft rubber, silicone, and low-surface-energy plastics shed ink. |
✅ | ✅ | ✅ | — | — | Flatter surfaces print sharper. Seal rough or porous wood first. | |
✅ | ✅ | ✅ | — | — | Cards, hang tags, gift cards. Hold thin sheets flat so they don't curl. | |
Lenticular | ✅ | ✅ | ✅ | — | — | Lenticular, 3D, and localized raised display effects. Align lenticular sheets precisely before printing. |
❌ | ✅ | ❌ | — | — | Dual UV covers leather and other flexible materials. Use flexible white ink on leather. | |
Tumbler / Cup | ✅ | ✅ | ✅ | Primer chosen to match the body material | Regular cylinders can run on the OR1. Where there's a handle, a complex curve, or a large step in height, UV DTF is the better first choice. | |
❌ | ❌ | ✅ | White ink & color ink pretreatment solution / DTF film | Garment Tray + heat press for apparel | This is a DTG/DTF textile workflow — UV direct printing is not recommended here. |

🌟 Table 2 · Which film goes with which workflow
Category | xTool film | What it does | Workflow | Single UV | Dual UV | UV + DT | Required consumables | Required accessories |
UV DTF film | A Film (sheet) | Carries the UV DTF design. For single and small-batch decals. (Gold foiling requires sheet A Film.) | UV DTF / gold foil UV DTF | ✅ | ✅ | ✅ | — | |
A Film (roll) | Carries batch designs — long graphics, repeats, high-volume stickers. | UV DTF | ✅ | ✅ | ✅ | — | ||
Transfer film | Required for gold foiling: moves the foiled design onto the object. | Gold foil UV DTF | ✅ | ✅ | ✅ | — | ||
B Film (roll) | Laminates over the A Film to build the peelable, re-applicable crystal-label structure. | UV DTF | ✅ | ✅ | ✅ | — | ||
Weeding film | Required for gold foiling: lifts surplus A Film adhesive for clean edges. | Gold foil UV DTF | ✅ | ✅ | ✅ | — | ||
3D label film | TPU 3D label transfer film / clear silicone label transfer film | Transfers 3D logos, 3D designs, and localized raised effects onto fabric. | 3D logo / 3D design transfer | ✅ | ✅ | ✅ | — | Heat press |
Foil film | Hot foil film — gold / silver / holographic | Adds metallic gold, silver, and holographic effects. | Gold foil effects | ✅ | ✅ | ✅ | — | |
Adhesive vinyl rolls | Vinyl, white | White-backed adhesive film for opaque stickers and labels. | UV direct printing (print and stick) | ✅ | ✅ | ✅ | — | |
Ultra-clear film | Transparent adhesive film — keeps the substrate color visible or gives a see-through look. | UV direct printing (print and stick) | ✅ | ✅ | ✅ | — | ||
Static cling film | Adhesive-free static cling for windows, displays, and short-term decoration. | UV direct printing (print and stick) | ✅ | ✅ | ✅ | — | ||
Fabric rolls | Canvas roll kit | Carries long fabric graphics for continuous roll printing and batch canvas work. | UV direct printing | ✅ | ✅ | ✅ | A specific pretreatment solution is required in DT mode | |
Fabric | 100% cotton canvas | Carries textile prints for cotton canvas and fabric goods. | DTG | ❌ | ❌ | ✅ | White ink & color ink pretreatment solution | Not required |
DTF film | Carries the DTF design; pairs with hot melt powder and a heat press to transfer onto fabric. | DTF | ❌ | ❌ | ✅ | Hot melt adhesive powder | Curing oven + heat press |

3. When to use primer for UV direct printing
UV direct printing puts ink straight onto the material, so everything depends on whether the ink grips that surface. Primer adds a stable bonding layer between the material and the UV ink — most useful on smooth, hard materials like glass, ceramic, metal, and acrylic. Used right, it reduces flaking, ink shrinkage, fuzzy edges, and poor scratch resistance.
- Check the material first. Smooth, hard materials — glass, ceramic, metal, acrylic — usually need primer.
- Prime the print area only. Cover the design area plus a small margin, not the whole piece.
- Keep it thin and even. Spread it lightly with a cotton pad, lint-free cloth, or brush head; avoid streaks, brush marks, and pooling.
- Let it dry. Load the piece only once the primed surface feels dry and no longer looks glossy. Print a white ink underbase too, or the result comes out gray.
- Don't rub it right after printing. Give a freshly cured UV ink layer time to stabilize before scraping or packing it.
4. How to add gold foil effects
Gold foiling isn't basic coloring — it's a visual upgrade that makes a piece read like a high-value gift. It suits brand logos, holiday cards, medals and nameplates, wedding favors, gift-box labels, and limited-edition stickers.
Materials that take foil well
- Flat rigid materials: acrylic, coated metal, sealed wood panels, cards, signage.
- Press-flat materials: some leathers, PVC board, gift tags.
- Finished UV DTF decals: crystal stickers, tumbler decals, decorative decals, brand stickers.
A few quick reminders
- Flatter is more reliable. Foiling suits flat or press-flat materials; for complex curves, do UV DTF first, then apply.
- Clean the surface first. Remove dust, grease, and finger oil, or the foil layer will bond unevenly, bubble, or lift.
- Don't go too fine. Very small text, intricate textures, and large solid fills all need a test print first.
- Secure the substrate. Clamp down sheet A Film and other thin, light media so it can't curl up and strike the printhead.
