Textile printing: the choice that saves you time, money and frustration
Textile printing seems simple at first glance: you have a logo, you have shirts, so you put it on. In practice, choosing between DTF, flex (HTV) and sublimation is exactly when projects slow down (or run smoothly). This guide was created for companies that need workwear, sports clubs that want names and numbers, schools and clubs that want a quick small run of merch, as well as makers who want to press their own with a heat press.
At the end, you'll know three things very specifically:
- Which technique technically suits your fabric (cotton, blend or polyester) and your design (full color, tight text or "imperceptible").
- Which workflow is realistic for your print run (1-25, 25-100, 100+) and deadline.
- What cost factors drive the piece price (without us pinning you down to price lists that vary by supplier anyway).
This decision aid is intentionally practical. You get a quick decision tree, a comparison framework, typical pitfalls per technique, and a set of checklists you can copy/paste into your briefing or order email. That way, you avoid the classic scenario: "It looked perfect on screen, but on the shirt it's dull/loose/feels like plastic."
Important: No technique is "always the best." The best choice is the technique that has the least risk on your fabric, with your design, within your time and budget.
Framework of terms: what do we mean by DTF, flex (HTV) and sublimation?
DTF (Direct To Film).
DTF is a transfer technique: your design is printed on a transfer film, then an adhesive powder (glue layer) is added, and a heat press is used to transfer it all to the textile. The big advantage is that you can relatively easily make full-color prints (including gradients and photo details) on many types of fabrics, including cottons and blends. The "feel" is usually slightly tactile: you have a thin layer on the fabric.
Flex / HTV (Heat Transfer Vinyl).
Flex film (HTV) is essentially cut film. You cut your design out of a colored film (usually on a cutter), remove the excess material (weeding/peeling) and press it onto the fabric. It excels at tight text, logos with 1-2 colors, and personalization such as names and numbers. It is less suitable for photos or complex full color designs, unless you work with special (more expensive) printable films.
Sublimation
Sublimation works differently: the ink "fades" into the material, so to speak. With heat, the dye moves from paper to polyester fibers (or a polymer coating in the case of hardgoods). As a result, the print is usually almost imperceptible and extremely colorfast on suitable material. The limitation is obvious: It works primarily on white or light polyester (dark cotton is a no-go if you expect true color coverage).
Quick decision tree (in 60 seconds)
Answer these four questions and in 80% of cases you'll be immediately in the right direction.
1) What fabric are you printing on?
- (Mostly) cotton → often DTF or flex
- Blends (cotton/polyester) → often DTF or flex (test!)
- Polyester sports fabric (light/white) → often sublimation (top) or flex/DTF for exceptions
2) What look do you want?
- Full color, gradients, photo → DTF (or sublimation if polyester is light)
- Sleek lettering, 1-2 colors → flex
- 'No tactile print' → sublimation (on light polyester)
3) Circulation & speed
- 1-25 → often DTF or flex (depending on design), sublimation on polyester
- 25-100 → workflow and preparation become dominant (DTF transfers can be efficient)
- 100+ → consistency, automation and error rate count more heavily (test protocol + delivery)
4) Use & wash resistance
- Sports (lots of rubbing/washing) → sublimation on polyester is strong; flex/DTF can also if pressed properly
- Hospitality/work (hot washing, dryer risk) → choose technique + maintenance rules consciously
- Events (short use, fast delivery) → speed and margin for error > "perfect" feel
The decision tree is your starting point. Then you want to check your choice against realistic details: how complex is your artwork, how thin are your lines, how dark is the fabric, and do you have time to test.
Comparison: DTF vs Flex vs Sublimation (what you really feel in workflow and results)
Comparison chart: DTF vs Flex vs Sublimation
The table below is not marketing; it is a practical reminder to help you quickly choose the right direction in a briefing.
| Feature | DTF | Flex (HTV) | Sublimation |
| Best for | Full color, small to medium print run | Text/logos, names/numbers | Polyester sports, 'all-over' look on light polyester |
| Fabrics | Often cotton/blends, also many synthetic (test) | Many fabrics (depending on film) | Mainly white/light polyester or coating |
| Feel | Slightly tactile | Film feel (varies by type) | Almost imperceptible |
| Turnaround time | Fast when transfers are ready | Fast with simple designs | Fast with polyester |
DTF in practice
When DTF is the best choice
- You have full color: logos with gradients, illustrations, small details, (almost) photo-quality.
- You want flexibility: the same design on multiple fabrics and colors.
- You work with small runs of merch (crew shirts, limited drops) where setup time still needs to remain low.
Pitfalls and quality factors
- Pressure, temperature and time determine adhesion. 'Just not' gives edges that dissolve later.
- Peel type (cold/warm) affects finish and chance of damage.
- Second press can improve adhesion and surface, but can also change gloss/texture.
Flex (HTV) in practice
When flex is the best choice
- You want tight lettering: names, back numbers, teamwear personalization.
- Your design is 1-2 colors and you want a clean, consistent look.
- You want control over color (foil color is exact) and you have little variation in artwork.
Pitfalls and quality factors
- Cut settings and blade depth: cutting too deep = fray; too shallow = poor release.
- Weeding takes time; complexity increases exponentially with small details.
- Multi-color designs require registration and additional heat load per layer.
Sublimation in practice
When sublimation is the best choice
- You work with polyester sportswear (white or light) and want a print that is "in" the fabric.
- You want maximum color fastness (on suitable material) and comfort.
Pitfalls and quality factors
- Ghosting: shifting of paper when opening/closing the press.
- Temperature and paper position affect sharpness.
- Cotton does not work "pure": you won't get true color coverage without special coatings/alternatives.
Practical tip: make your choice not only on "quality," but on risk. If your fabric or usage falls outside the sweet spot of a technique, your chances of failure increase - and that margin of error is often more expensive than 10% difference in piece price.
Cost factors (without price list) + delivery + maintenance
Cost factors explained (without a price list)
Asking "what does it cost per shirt?" makes sense, but a fixed price is almost always misleading without context. What you can do: understand which buttons drive the price.
1) Setup and preparation
- Design check, sizing, proofing or test press.
- For flex: cutting file, evisceration; for DTF: print/film/powder; for sublimation: color forecast on polyester.
2) Production time per piece
- Positioning (chest/back/sleeve) and repeatability.
- Multi-color flex = additional operations.
- DTF can be fast if transfers are prepared efficiently.
3) Material selection and error rate.
- Cheap foils/films can fail faster.
- Dark fabrics and difficult materials increase the chance of mispress.
- Failure is not only loss of material, but also loss of time.
Delivery checklist (files).
If you do this right, you often gain days in turnaround time.
- Logos: preferably vector (AI/PDF/EPS) so lines stay sharp.
- Raster (PNG/JPG): delivered sufficiently large; avoid scaled up small files.
- Transparency: supply PNG with transparent background (no 'white box').
- Color expectation: specify desired color (e.g. Pantone reference) or accept approximation on textile.
- Placement: chest/back/sleeve + desired dimensions in cm.
Washing and maintenance (summary).
The better your technique, the better your washing results - but maintenance remains crucial.
- Wash inside out and preferably low temperature.
- Avoid ironing directly over the print.
- Be careful with dryer/over heat.
Want to really button this up (especially with teamwear or workwear)? Include short washing instructions in your order or provide a care card. This reduces complaints and extends the life of the print.
