What Is UV Printing?
UV printing jets UV-curable inks onto the surface and cures them instantly with UV-LED lamps. Curing turns the liquid ink into a solid film. Because curing is immediate, prints remain sharp on many materials.

Where UV shines
- Hard goods: acrylic signage, metal nameplates, stainless drinkware (with surface prep), wood plaques, phone cases, power banks, USBs.
- Special effects: gloss/matte spot varnish, textured “embossed” layers, Braille dots, simulated doming.
- Short-run packaging: boxes, sleeves, labels, rigid samples.
- Color on clear: white ink + CMYK on glass/acrylic for backlit effects.
What to know about adhesion
Different substrates bond differently. Many plastics (PP, PE, some silicones) need primer or corona/ flame treatment. Metals and glass benefit from thorough cleaning and, sometimes, adhesion promoters. Erasmart can advise primer selection based on your bill of materials.

Where DTF shines
- Garments: cotton tees, hoodies, workwear, performance polyester, blends, nylon (with appropriate settings).
- Inventory flexibility: print transfers ahead of time; press on demand.
- No pre-treatment: unlike DTG on dark shirts, DTF does not require pre-treat.
- Fine detail: small text and gradients transfer cleanly with good films.
Pressing basics (typical ranges)
- Temperature: ~150–170 °C (302–338 °F)
- Time: 10–20 seconds press + 5–10 seconds post-press (if needed)
- Pressure: medium-firm, even pressure
- Peel: cold or warm depending on film (follow film spec)

Image Quality, Color & Special Effects
UV Printers
UV delivers razor-sharp edges and very small text readability due to instant curing. You can stack multiple layers for tactile textures and apply spot gloss for premium packaging looks. White ink on transparent items enables vivid backlit graphics.
DTF Printers
DTF pigment inks provide rich solids and smooth gradients on textiles. A good ICC profile controls color on a wide range of fabrics. The final print has a soft-to-medium hand; premium films and powders further soften the feel.
Material Compatibility
| Material | UV Printer | DTF Printer |
|---|---|---|
| Cotton/Blends | Not typical | Excellent |
| Polyester & Performance Wear | Not typical | Excellent |
| Nylon | Rare, needs primer | Good (test for press settings) |
| Leather (genuine/PU) | Good (with primer) | Good (press-safe) |
| Wood | Excellent | Not applicable |
| Acrylic | Excellent | Not applicable |
| Glass | Good (with adhesion promoter) | Not applicable |
| Metals (Al/SS) | Good (cleaning/primer) | Not applicable |
| Coated Paperboard | Excellent | Not applicable |
Durability & Care
- UV: Great scratch and chemical resistance on rigid goods. For outdoor exposure, add a clear UV over-varnish or laminate if the substrate demands it.
- DTF: Wash-durable when pressed correctly; turn garments inside-out, use mild detergents, avoid over-drying. Quality powder and proper cure prevent cracking.
Workflow & Throughput
UV (Direct to Object)
- Load jig/fixture, align artwork.
- Clean/prep (if needed), print CMYK+W/varnish.
- Ready to ship immediately (no drying time).
Throughput tip: Nest many items in one bed; run batch jigs.
DTF (Transfer-Based)
- Print to PET film (CMYK+W).
- Apply powder & cure (automatic shaker/oven or manual).
- Press onto garment; peel; optional post-press.
Throughput tip: Print/stock transfers in bulk; press on demand during peak hours.
Cost & Pricing Considerations (Indicative)
| Cost Element | UV Printer Cost | DTF Printer Cost |
|---|---|---|
| Hardware | Higher upfront | Lower to mid upfront |
| Inks | UV-curable (premium) | Water-based pigment (economical) |
| Consumables | Primers, jigs, occasional varnish | PET film, adhesive powder, heat press platens |
| Per-Item Cost | Low on small hard goods (ink pennies + prep) | Very low per transfer; film/powder dominate |
| Labor | Fast per item with jigs | Fast per garment once transfers are ready |
| Pricing Power | High on unique hard goods & special effects | Strong for custom apparel & personalization |
Bottom line: UV wins on high-margin hard goods and premium effects; DTF wins on volume apparel and flexible inventory.

Frequently Asked Questions (FAQ)
Q1: Can a UV printer replace a DTF printer?
Not generally. UV excels on rigid/ coated items and effects; DTF excels on textiles. Many shops run both.
Q2: How does DTF compare to screen printing?
DTF has lower setup and full-color at any quantity; screen printing wins for very large runs with spot colors at the absolute lowest cost per unit.
Q3: Is white ink maintenance difficult?
White ink is heavier and can settle. For both UV and DTF, stick to regular agitation and daily nozzle checks; follow Erasmart’s maintenance schedule to avoid clogging.
Q4: What about stretch and cracking on DTF?
Use quality film/powder, ensure complete adhesive cure, and press with correct pressure & temperature. Done right, DTF transfers stretch and resist cracking.
Q5: Will UV prints stick to glass and metal?
Yes, with thorough cleaning and often a primer/adhesion promoter. Always test your exact substrate.
Q6: Are UV inks safe for items that touch skin?
Once fully cured, UV inks form a solid film. For direct and prolonged skin contact, confirm compliance for your application and consider a clear overprint to isolate the ink layer if needed.
Q7: Can I do photorealistic prints?
Yes. Both technologies handle high-resolution images. UV provides ultra-crisp dots on rigid media; DTF creates smooth gradients on garments.
Q8: What press settings should I start with for DTF?
As a starting point: 160–165 °C for 12–15 seconds, medium-firm pressure, cold or warm peel per film spec. Then validate with wash tests.
