Direct-to-Garment (DTG) printing operates like an industrial inkjet printer for apparel. Instead of utilizing physical mesh screens to push ink layer by layer, DTG prints specialized aqueous CMYK inks directly onto the fabric surface from digital artwork files. This makes it the absolute gold standard for complex photographic graphics, gradients, and multi-color artwork where traditional screen printing setups become cost-prohibitive.
This technique is highly favored by streetwear startups and print-on-demand brands executing complex graphics without committing to massive bulk order minimums.
Use DTG for highly detailed, photorealistic graphics or multi-color gradients on cotton fabrics, especially for short runs. For large bulk production of low-color vector designs, screen printing remains more cost-effective.
DTG vs. Screen Printing
Why fabric composition dictates your results
DTG inks are formulated specifically for natural fibers. 100% combed and ring-spun cotton yields the sharpest print resolution and highest color vibrancy because the fibers absorb water-based pigments seamlessly. While polyester blends can be printed, the synthetic yarns do not absorb the ink correctly, leading to dull colors, a rough texture, or premature washing fade.
Furthermore, printing on dark garments requires an industrial white underbase layer combined with a liquid pre-treatment solution. Without proper execution, this underbase can slightly stiffen the hand feel compared to the weightless absorption seen on white garments.
Production specs for your tech pack
| Spec | Value | Notes |
|---|---|---|
| Print method | Direct-to-Garment (DTG) | Specify continuous digital inkjet printing |
| Ink chemistry | Water-based pigmented CMYK | Must meet eco-standards (e.g., Eco Passport) |
| Fabric limitation | Min. 80% Cotton recommended | 100% cotton optimal to avoid dye migration |
| Artwork resolution | 300 DPI minimum at actual size | Submit as transparent PNG or vector asset |
| Pre-treatment | Required for dark colors | Prevents white underbase from sinking into fabric |
| Color matching | CMYK approximation | Exact Pantone matches cannot be guaranteed |
In FlatLabs PRO, when selecting DTG, your tech pack automatically generates file resolution alerts and fabric mapping safety flags to warn factories against choosing high-polyester blends.
