DTG Printing for Beginners: Process, Pretreat and When It Fits
DTG printing for beginners: how direct to garment works, pretreat and cure basics, garment limits, and when DTG fits versus DTF or screen (comparison linked, not duplicated).
Beginner DTG guide: the seven step process, garments and pretreat, equipment building blocks, cost drivers and common mistakes.
DTG printing for beginners comes down to three stages: pretreat the garment if the design or garment needs it, print water-based pigment ink straight onto the shirt with a specialized inkjet printer (white underbase first on darks), then heat-cure the ink to the ink maker's spec; it fits short runs, many colors and photo-style art on cotton-rich garments.
DTG defined: DTG (direct to garment) prints ink directly onto the fabric through a RIP-driven inkjet workflow. Most dark cotton garments need pretreat for white ink, curing is mandatory, and DTG suits short runs and full color art better than it suits high-volume spot color work.

What DTG Printing Is (and Is Not)
DTG is a digital process: a print head jets tiny drops of water-based pigment ink onto the garment, much like a paper inkjet, with software (a RIP) controlling color and the white layer. It is not a transfer process; nothing is pressed on from film or paper. It is also not screen printing: there are no screens or per-color setup, so a one-off and a 24-piece run use the same workflow.
How DTG Printing Works Step by Step
- Pretreat if required. Apply pretreat to the print area, usually needed for white ink on darks.
- Dry. Dry the pretreat fully, usually on a heat press, which also flattens fibers.
- Load the garment. Place it flat and wrinkle free on the printer platen.
- Print white, then color, as the RIP requires. On darks the printer lays a white underbase first, then color; on lights, color may print alone.
- Cure. Cure on a heat press or dryer to the ink maker's time, temperature and pressure.
- Cool. Let the print cool before folding or stacking.
- Wash-test. Wash a sample per care instructions before a production run.
Garments, Pretreat and Feel
DTG inks bond most reliably to natural fibers, so 100% cotton or garments with a cotton-rich print face are the usual starting point. Smooth, tightly knit blanks print sharper. Polyester and performance fabrics often need different chemistry or a different method. Dark garments printed with white ink need pretreat; light garments printed in color only often do not. The print feels soft on lights; a white underbase on darks adds some hand. For sourcing blanks, see Wholesale Blanks Buying.
Equipment Building Blocks (Printer, Pretreat, Cure)
| Building block | What it does | Questions to ask |
|---|---|---|
| DTG printer and RIP | Prints white and color; RIP manages color and white layers | Print size, white ink handling, daily maintenance, ink and parts cost, support |
| Pretreat method | Sprayer or pretreat machine | Repeatability, volume, ventilation and cleanup |
| Drying and curing | Heat press or conveyor dryer | Platen size, temperature accuracy, throughput |
| Work area | Clean, stable space for printer and garments | Humidity and temperature limits in the printer spec, power, ventilation |
The buying mindset in What to Know Before You Buy a DTF Printer carries over: get maintenance, consumables and support in writing. DTG buy questions differ in detail, especially white ink upkeep and pretreat. For layout and utilities, see the Shop Setup Guide.
When DTG Fits Your Order Mix
DTG tends to fit when orders are small, designs have many colors or photo detail, and garments are cotton-rich. It tends to fit less well when you run large quantities of simple spot color designs or mostly polyester garments. Many shops also outsource DTG at first to test demand before buying equipment.

Cost Drivers Without Sticker Prices as Gospel
Printer prices vary widely by class, region and bundle, so this guide does not quote a price band. Per-piece cost is driven by ink use (especially white ink on darks), pretreat, blank cost, labor per piece, maintenance downtime and remakes. Price the full workflow, not only the printer. See Screen vs DTF Pricing for how per-piece logic changes by method, and Start a Custom Apparel Business for planning the business side.
Common Beginner Mistakes
- Skipping or under-drying pretreat on dark garments.
- Under-curing because the press display was trusted without checking actual temperature.
- Printing on polyester-heavy blanks without testing.
- Ignoring daily printer maintenance, which leads to clogged heads and downtime.
- Pricing from ink cost alone and forgetting pretreat, labor and remakes.
- Skipping a wash test before the first real order.
Frequently Asked Questions About DTG Printing for Beginners (FAQ)
What is DTG printing?
Direct to garment printing: an inkjet printer applies water-based pigment ink straight onto the garment, then the ink is heat-cured.
How does DTG printing work?
Pretreat the garment if needed and dry it, load it flat, print a white underbase then color on darks (color only on many lights), then cure to the ink maker's spec and wash-test a sample.
Is DTG better than DTF?
Neither wins in general. DTG prints directly into cotton-rich garments and suits short, full color runs; DTF prints onto film and is pressed on, which widens fabric options. Choose by your garments, order sizes and art. See the full comparison in DTF vs DTG vs Screen Printing.
What shirts work well for DTG?
100% cotton or cotton-rich garments with a smooth, tight knit. Test blends first, and expect polyester to need a different approach.
Do I need pretreat for DTG?
For white ink on dark garments, generally yes. For color only on light cotton, often no. Follow your ink and pretreat maker's guidance and test.
Settings and fabric guidance in this guide are general starting points, not universal specs. Figures vary by printer, ink, pretreat and garment; check the supplier spec before production.
DTG is easier to judge once you have seen printers, pretreat and cure steps run on real garments. Browse more guides in the DAX Learning Hub, and check cities and dates on the DAX show schedule when you are ready to compare DTG workflows with suppliers in person.
