DTG, the one-off machine that fades faster than the shirt.
Water-based pigment ink jetted directly onto pretreated cotton. Great for a single custom shirt in an hour. Worse than DTF at every wash count that matters.
A production-floor definition, not a spec sheet.
DTG is inkjet printing onto fabric. A pretreatment fluid is sprayed onto the garment to hold the ink and drop it into the fibers instead of beading on the surface. The garment is loaded onto a flat platen, a modified inkjet head prints CMYK plus white directly onto the pretreat, and the print is cured under a heat press or conveyor at roughly 330 F for two to three minutes.
The strength of DTG is one-off economics. There is no film to print, no powder to dust, no setup step. A single shirt with a single graphic ships in an hour. That is why print-on-demand marketplaces built their business on DTG platens.
The weakness is durability and fabric range. DTG only works on 100% cotton or high-cotton blends with pretreatment. Poly is out. Tri-blend needs a soft-hand pretreat and still runs weak. The pretreat step is fussy on dark garments, over-spray causes halos, under-spray causes wash-out, and the pretreat itself yellows on some cotton varieties.
In practical shop terms, a well-run DTG prints holds roughly 20 to 30 washes. A DTF transfer on the same fabric holds 50 to 60. That is why print-on-demand shops with volume have already migrated to DTF where they can.
Compatibility, capability, and where it earns its price.
Structured spec fields for this decoration method. Not a manufacturer datasheet, not marketing copy. The judgment we would give on a phone call, written down so a buyer or a retriever can act on it in three hops.
Fabric compatibility
- 100% cotton (ringspun)Good, best DTG fabric
- 50/50 cotton-polyWorkable, print softer than pure cotton
- Tri-blendMarginal, wash count drops sharply
- 100% polyesterDo not attempt, pretreat incompatible
- Cotton fleeceWorkable, expect variable pretreat coverage
- Performance knitDo not attempt

Best applications
- Single custom shirt orders (Etsy, print-on-demand)
- Photographic art on 100% cotton
- Sample and prototype runs before committing to method

Polyester or poly-blend performance wear.
DTG pretreatment does not bond to polyester fibers. The ink beads and washes off. Any performance fabric routes to sublimation or DTF with poly-blocker.

DTG fades at 20 to 30 washes. That is fine for print-on-demand where the customer expects one season. It is not fine for retail brands who guarantee product life.
Order this instead: DTF Transfers method500-shirt run of the same graphic on dark garments.
Pretreatment cost times 500 shirts plus DTG print time at 45 seconds per shirt equals 6 hours of press time. A DTF gang sheet with 500 designs presses in 90 minutes and lasts twice as long.

Over-spraying pretreatment.
The pretreat leaves a visible halo on the fabric that outlives the print. Halos on a black shirt read as a rectangle of dye stain around the graphic. Meter the pretreat exactly, or route the job to DTF where pretreat is not required.
Skipping the humidity check.
DTG print quality collapses above 70% relative humidity. The ink dries too slowly and pools. A dehumidified print bay is not optional on any DTG production floor.
Selling DTG as retail-durable.
The wash test does not lie. Twenty to 30 cycles is the honest number. If your customer expects a shirt they can wear for years, do not sell them DTG.
DTG is a specialist tool. DTF handles the rest.
Golden DTF does not run DTG in-house. If your job is a single one-off on 100% cotton and same-day matters more than wash-life, DTG has a place. Otherwise, DTF wins on unit cost, fabric range, and durability.
