Screen, DTG, DTF: How T-Shirt Printing Actually Works, Explained From the Press Room

Three letters — DTG, DTF — and one old workhorse, and most brands cannot say what physically happens in any of them. Here is the whole landscape in one analogy: screen printing is a stamp, DTG is an inkjet printer aimed at fabric, and DTF is a printed sticker fused on with glue. Everything else — cost, feel, durability, fabric limits — follows from those three mechanisms. We run all three in our Dongguan factory; this is the explainer we wish every first brief came after. (If you already know the mechanics and just want to choose, our decision guide is the companion piece.)

Screen printing: the stamp

For every color in the artwork, a screen is made: a fine mesh stretched on a frame, coated so that ink can only pass through where the design is. The garment lies flat; a squeegee drags ink across the screen, pushing it through the open mesh onto the fabric. One screen, one color, one pass — a four-color logo is four screens printed in register, with a flash-dry between layers on dark garments (white underbase first, colors on top).

The ink — usually plastisol — does not dry. It fuses: the printed garment rides a conveyor dryer until the entire ink film reaches about 160 °C, at which point it becomes the tough, elastic layer that survives years of washing. That cure step is where quality lives or dies, and it is invisible at delivery — the full chemistry is in our durability guide.

The stamp logic explains the economics: making stamps costs setup (per color), pressing them costs almost nothing per unit. Screen printing rewards volume and bold, few-color artwork — which is why it still owns streetwear's big graphic hits, like our heavyweight screen-printed boxy tees.

DTG: the inkjet aimed at fabric

Direct-to-garment is literally an inkjet printer whose bed holds a t-shirt. Water-based pigment inks spray directly into the fabric surface — millions of droplets, any number of colors, photographic gradients, zero setup.

Two mechanical facts define it. First, pretreatment: before printing (essential on darks), the garment is coated with a cationic fluid that electrostatically grabs the pigment at the surface — without it, ink wicks into the fibers and the print looks washed out and dies early in the laundry. Second, the ink bonds to cotton: DTG performs best on high-cotton, smooth-surfaced fabric (one more reason yarn quality matters — see our ring-spun guide). After printing, a heat press sets the ink.

Because ink enters the fabric rather than sitting on it, DTG has the softest hand of the three — the print is in the shirt. The trade: colors read slightly softer than screen ink, especially on dark heavyweight fleece, though it handles full-color art on garments like our DTG-printed heavyweight zip hoodie where screens would need a dozen colors.

DTF: the printed sticker, industrialized

Direct-to-film is the newest of the three and the fastest-growing, because it removes almost every restriction — by changing where the ink lands.

The design is inkjet-printed onto a PET film, mirrored, in full color — then a layer of white ink over it (which will face the fabric and make colors pop on any ground). While the ink is wet, hot-melt adhesive powder is applied and the film runs through an oven that melts the powder into a uniform glue layer.

That finished film is the product: press it onto a garment (industry parameters cluster around 150-170 °C for 7-20 seconds, pressure and peel style per film system), peel, and give a short second press to seat the ink — the step transfer makers themselves call essential for wash durability.

Because the print is built on film and glued on, DTF barely cares what the garment is: cotton, polyester, blends, nylon — no pretreatment, no screens, fine detail and vivid color from unit one. Its honest trade-off is the same as its mechanism: the print is a layer on the fabric. Small and medium graphics wear beautifully; a huge solid panel can read like a decal and print-room practice mitigates it with halftones and knockout detailing. DTF is also the modern heir of the heat-transfer family — the technique that used to mean cut vinyl (HTV, one color per layer) or screen-printed plastisol transfers pressed from release paper. Same press, new engine.

The three systems, side by side

	Screen	DTG	DTF
Mechanism	Ink pushed through stencil	Inkjet into fabric	Inkjet onto film, glued on
Setup per design	Screens per color	None	None
Colors / gradients	Costly beyond ~6 colors	Unlimited, photographic	Unlimited, photographic
Fabric range	Wide (ink systems per fiber)	High-cotton best	Nearly any, incl. nylon
Hand / feel	Ink layer; thin to bold	Softest — ink in fiber	Film layer on fabric
Where it struggles	Small runs, photo art	Darks on poly, muted on fleece	Large solid panels, high-stretch zones
Unit economics	Best at volume	Flat per unit	Flat per unit, gang-sheet friendly
Signature use	Bold graphic hits at quantity	Full-color art on cotton	Any-fabric detail, small drops, mixed placements

Care differs by mechanism — tell your customers

	Screen (cured plastisol)	DTG	DTF
Wash	Inside-out, cool	Inside-out, cool	Inside-out, cool, gentle
Dry	Low tumble fine	Low tumble	Low tumble or hang
Iron	Not on the print	Not on the print	Never on the print

None of these rules is decoration paranoia — each maps to the mechanism (fused ink film, pigment-on-fiber, glued film layer). Care copy belongs in your private-label package, and we include technique-appropriate care wording by default.

How we choose between them (and how to brief us)

Send artwork, placement, garment fabric, and quantity per colorway — the technique often chooses itself: bold few-color art at volume → screen; photographic art on cotton → DTG; mixed fabrics, fine detail, or fast small drops → DTF. Many programs combine them on one garment (screen hit front, DTF sleeve detail). We quote the route with reasoning after sufficient project details are reviewed, and every technique rides the same program: MOQ starting at 50 pieces, with the final minimum depending on the product, fabric, wash, and customization, samples in 10-15 working days at a project-specific quoted amount, and bulk in 20-30 working days after approval. The full menu is on our printing capability page.

FAQ

Is DTF better than screen printing? Different machines for different jobs. DTF wins on fabric range, detail, and small quantities with zero setup; screen wins on bold color impact and unit cost at volume. On a 500-piece single-design run of a 3-color logo, screen usually quotes lower and hits harder; on a 50-piece multi-fabric drop with detailed art, DTF is the obvious call.

Is DTG the same as DTF? No — one letter, different universe. DTG jets ink directly into the garment fiber (softest hand, cotton-loving); DTF prints onto a film that is glued onto the garment (any fabric, slightly more surface feel). The names are the industry's own fault.

Which method lasts longest in the wash? Properly executed, all three survive normal garment life; failure is almost always a process error (under-cured screen ink, skipped DTG pretreat, wrong DTF press parameters) rather than the technology. What to demand from any factory is the same: a wash-tested sample — see our durability guide.

Can you mix printing methods with washes and embroidery? Yes — sequenced correctly: garments are washed before decoration, and heat-sensitive decorations are planned so later steps never re-cook earlier ones. That sequencing is part of what a factory's production plan is for.
