What Is Direct to Garment Printing?

Direct to garment printing (DTG) is a digital decoration method that uses a modified inkjet printer to spray water-based ink directly onto fabric. Unlike screen printing, which requires separate screens for each color, DTG prints from a digital file — making it ideal for complex, full-color designs, small runs, and on-demand production.

 

How DTG Printing Works

The DTG process involves three steps: pre-treatment, printing, and curing.

Pre-Treatment

Before printing, the garment is sprayed with a pre-treatment solution that flattens loose fibers and chemically prepares the surface for ink adhesion. Pre-treatment is essential on dark-colored garments and strongly recommended on light ones for consistent results. Without it, ink sits on top of fibers rather than bonding to them, leading to faded, uneven prints after washing.

Printing

The pre-treated garment is loaded onto a flat platen inside the DTG printer. The print head moves across the surface and jets ink in precise droplets, reproducing the digital design at high resolution. On dark garments, a white ink underbase is printed first to ensure color accuracy — without it, the garment color bleeds through and mutes the design.

Curing

After printing, the garment is passed through a heat tunnel or heat press to cure the ink. Curing bonds the ink to the fibers permanently and determines wash durability. Insufficient curing is the most common cause of premature print fading.

 

Best Fabrics for DTG Printing

DTG ink is water-based and bonds best to natural and semi-natural fibers. Fabric choice directly affects print quality and durability.

•       100% cotton: The best substrate for DTG. Combed ringspun cotton produces the sharpest edges and most vibrant colors. Open-end cotton's rougher surface causes ink to bleed slightly, softening fine detail.

•       80/20 or 50/50 cotton-poly blends: Acceptable results at higher cotton ratios. Below 50% cotton, ink adhesion becomes inconsistent and colors appear duller.

•       Tri-blends: The rayon content adds softness but can affect ink absorption consistency. Best results come from tri-blends with 50% or more cotton.

•       100% polyester: Not recommended for DTG. Polyester fibers repel water-based ink and produce washed-out, short-lived results. Use sublimation for polyester instead.

 

Pros of DTG Printing

•       No minimum order: Print one shirt as cost-effectively as printing ten. There are no screens to set up, so setup cost is essentially zero.

•       Unlimited colors: DTG handles photographic images, gradients, and designs with hundreds of colors at no additional cost per color.

•       Soft hand feel: Ink bonds into the fibers rather than sitting on top, so the print has minimal texture difference from the surrounding fabric.

•       Fast turnaround: No screen setup means individual pieces can be produced and shipped same-day in many print shop environments.

•       Eco-friendly inks: Water-based DTG inks produce less chemical waste than plastisol inks used in screen printing.

 

Cons of DTG Printing

•       Higher per-unit cost at volume: DTG does not scale as cost-efficiently as screen printing. For orders above 50 to 100 units of the same design, screen printing typically becomes cheaper per unit.

•       Fabric restrictions: DTG only performs well on cotton-dominant fabrics. It cannot be used on polyester, nylon, or other synthetic substrates.

•       Pre-treatment requirement: Dark garments require pre-treatment, which adds a processing step and introduces a variable that affects final color accuracy if not applied consistently.

•       Wash durability: DTG prints fade faster than screen prints or embroidery if care instructions are not followed. Cold water washing, no tumble drying, and turning the garment inside out extend print life significantly.

•       Limited placement: Most DTG printers print within a defined platen area. All-over printing and placements on sleeves, pockets, or backs require repositioning, adding time per piece.

 

DTG vs. Screen Printing vs. DTF: Quick Comparison

•       DTG vs. screen printing: DTG wins on color complexity, small run cost, and design flexibility. Screen printing wins on per-unit cost at volume (50+ units), durability, and fabric range.

•       DTG vs. DTF: DTF (direct to film) transfers work on a wider range of fabrics including polyester and blends, require no pre-treatment, and can be produced in advance for heat-press-on-demand fulfillment. DTG produces a softer hand feel and is better for high-volume on-demand production. Both handle full-color designs.

•       DTG vs. embroidery: Embroidery is more durable and communicates premium quality but cannot reproduce photographic detail or gradients. DTG is better for complex, multi-color artwork; embroidery is better for logos and simple marks on premium blanks.

 

When to Use DTG Printing

DTG is the right choice when:

•       The design is full-color, photographic, or contains gradients that screen printing cannot reproduce cost-effectively.

•       The order is a small run — typically fewer than 50 units — where screen printing setup fees would make the per-unit cost prohibitive.

•       Products are made to order individually, as in a print-on-demand e-commerce or custom merchandise program.

•       The blank is 100% cotton or a high-cotton blend, which provides the best printing surface for DTG ink adhesion and color vibrancy.

 

DTG Print Care Instructions

DTG prints last significantly longer when cared for correctly. The key points:

•       Turn the garment inside out before every wash.

•       Wash in cold water on a gentle cycle.

•       Air dry or tumble dry on low heat. High heat degrades the ink bond.

•       Do not iron directly over the print.

 

Frequently Asked Questions

What is DTG printing used for?

DTG is used to print custom designs directly onto garments — most commonly t-shirts and hoodies — without screens or transfers. It is the standard method for small-run custom apparel, print-on-demand businesses, and any program requiring full-color or photographic print quality.

How long does a DTG print last?

A well-cured DTG print on 100% cotton, washed in cold water and air dried, typically lasts 50 or more wash cycles before visible fading. High heat drying and neglecting to turn the garment inside out significantly reduce that lifespan.

Is DTG printing good for dark shirts?

Yes, but it requires a white ink underbase printed first, which increases ink consumption and cost per unit. Pre-treatment consistency is also more critical on dark garments because any uneven application shows through in the final print.

What is the minimum order for DTG printing?

There is no minimum order requirement for DTG — a single garment can be printed at the same per-unit setup cost as a larger run. This makes it the most cost-effective decoration method for runs of one to approximately 50 units.

What is the difference between DTG and DTF printing?

DTG prints ink directly onto the garment through a specialized printer and requires cotton-rich fabric and pre-treatment. DTF prints onto a film which is then heat-transferred onto the garment, works on virtually any fabric type, and requires no pre-treatment — making it more versatile but producing a slightly different hand feel.
