Impressora UV DTF vs Impressora UV: Qual é a diferença e qual você deve comprar?
If you’re shopping for a “UV DTF printer,” you’ll quickly notice that people use the term in two different ways:
UV Printer (traditional UV printing) = prints directly onto the object/substrate, curing ink instantly with UV light.
UV DTF (UV Direct-to-Film transfer) = prints onto a special film (often called Filme A/B) first, then you transfer the design onto the product like a premium decal (“crystal label”).
Both use UV-curable inks and UV curing, but the workflow, materials, and business fit are very different.
Quick Comparison
| Category | UV DTF (Film Transfer) | UV Printer (Direct-to-Object) |
|---|---|---|
| “Where do you print?” | On Filme A, then laminate with Filme B and transfer | Directly on the product/substrate |
| Melhor para | Muitos small items, mixed shapes, quick personalization, “crystal label” decals | Flat panels, signage, rigid media, production runs, direct-to-object printing |
| Extra equipment | Commonly a laminador (or integrated unit) | Often none beyond printer; rotary/fixtures for cylinders (if needed) |
| Look & feel | Raised / glossy “label” aesthetic | “Printed-on” look; can be matte/gloss/texture depending on ink set |
| Common products | Tumblers (as decals), phone cases, gift boxes, promotional items | Acrylic/wood/PVC boards, signs, control panels, packaging prototypes |
What Is a Impressora UV?
UM Impressora UV jets UV-curable ink onto a surface and cures (hardens) it immediately with UV light. Because curing happens instantly, UV printing is known for crisp detail, vibrant color, and fast turnaround on many non-porous materials.
Common UV printer types
- UV flatbed: prints on rigid sheets and objects placed on a flat table/bed.
- Roll-to-roll UV: prints on flexible media (films, banners, etc.).
- Flatbed + rotary attachment: can print on cylindrical items like bottles and mugs, depending on configuration.
Best when: you can physically place or fixture the item on the printer and want the design printed directly on it.

What Is DTF UV (UV Direct-to-Film)?
DTF UV is a transfer method. You print the design onto Filme A, cure it, then laminate with Filme B and transfer the graphic onto the product surface by pressure—like applying a premium decal.
This is why UV DTF is often described as “crystal label” production: it’s not direct printing on the object; it’s printing a transferable graphic that can be applied to many products.
Typical UV DTF workflow (AB Film)
- Print the design on Filme A (UV ink + UV curing)
- Laminate with Filme B
- Peel/transfer onto the final item
- Finish by removing the carrier layer
Best when: you sell lots of small personalized products, want “sticker-like” transfers, or need a method that works across many SKUs without building complex fixtures.

Biggest Differences That Affect Your Business
1) Workflow & labor
- UV Printer: Load item → print → done (fast and direct), but requires positioning/fixtures for odd shapes.
- UV DTF: Print → laminate → apply/transfer → done. More steps, but often less fixturing headache for varied products.
Practical takeaway:
If you’re doing high-mix, small-run personalization (many item types per day), UV DTF can be easier to operate consistently.
2) What products each method “naturally” excels at
UV DTF excels at:
- Customized tumblers and bottles (as a decal transfer)
- Phone cases, small gift items, promotional products
- Brand labels for packaging, boxes, and accessories
UV Printer excels at:
- Acrylic signs, PVC boards, wood panels
- Industrial nameplates, control panels, prototypes
- Larger rigid sheets and flat production work
3) Finish, texture, and customer perception
- UV DTF commonly produces a label-like finish that customers associate with premium branding (gloss, raised edges, “crystal” look).
- UV direct printing looks like it’s printed onto the surface, and you can choose ink sets/varnish/texture options depending on the printer and workflow.
4) Durability in real life
Durability depends on ink system, substrate compatibility, and surface prep—but generally:
- UV printing (direct): Can be very durable when ink adheres well to the substrate and the correct process is used.
- UV DTF: Durability behaves like a high-performance decal/label—excellent for many use cases, but abrasion, harsh chemicals, and extreme heat can reduce lifespan depending on film/adhesive and the surface.
Rule of thumb:
If the product will be heavily scraped, chemically cleaned, or exposed to extreme conditions, test your exact material + ink + process before promising “permanent.”
Cost & Equipment: What You Actually Need
UV DTF typical setup
- UV printing capability (dedicated UV DTF unit or UV printer configured for DTF)
- AB film (Film A + Film B)
- Often a laminador (some systems integrate this)
UV printer typical setup
- UV flatbed / roll-to-roll / hybrid UV printer
- Fixtures for repeated products (optional but recommended)
- Rotary attachment for bottles/cylinders (optional, model-dependent)
Cost drivers (not just purchase price):
- Consumable waste (film/lamination scraps in UV DTF)
- Fixturing time and misprints (direct UV on odd objects)
- Maintenance: nozzle checks, cleaning cycles, environment control
Which One Should You Choose?
Escolher DTF UV se você:
- Sell personalized gifts and promo items (many SKUs)
- Need an easier path for mixed shapes without complex fixtures
- Want to sell or apply premium “crystal label” style transfers
Escolha um Impressora UV se você:
- Primarily print on flat rigid materials (signage, panels, boards)
- Want direct-to-object production with fewer steps
- Have repeatable product shapes or can build fixtures for efficiency
Escolher ambos if you’re building a full personalization shop:
- UV printer for boards/signs + UV DTF for small goods/labels
This pairing covers the widest set of profitable orders.
Common Mistakes (and how to avoid them)
UV DTF mistakes
- Skipping surface cleaning → edge lift, bubbles
- Poor lamination → wrinkles, silvering, inconsistent transfers
- Expecting perfect adhesion on deeply textured surfaces
UV printer mistakes
- Printing on incompatible substrates without prep/primers
- No fixture strategy → slow positioning, higher scrap rate
- Ignoring height/clearance limits on thick objects (risk of head strikes)
Perguntas frequentes
1) Is a UV DTF printer just a UV printer?
Not exactly. UV DTF is a transfer workflow. Many UV DTF systems use UV printing technology, but the key is printing to film and transferring, often with lamination.
2) Do I need a laminator for UV DTF?
In most AB-film workflows, yes (unless you buy an integrated all-in-one unit).
3) Can a UV printer print on tumblers?
Often yes, if the printer supports a rotary attachment or proper fixturing—but it depends on the model and setup.
4) What does AB film mean?
AB film generally refers to Filme A (print layer) and Filme B (lamination/transfer layer) used to create transferable UV DTF decals.
5) Is UV printing “safe” to run in a small shop?
It can be, if you follow SDS guidance, PPE, and ventilation. Safety guidance commonly highlights skin/eye exposure risks and sensitization concerns with UV materials and inks.
Conclusão
- Impressora UV = best when you want direct printing onto flat panels or fixture-friendly objects with a streamlined workflow.
- DTF UV = best when you want transfer decals (“crystal labels”) that apply across many products and shapes with less fixturing complexity.
