How to Custom Print Shirts? | Pick The Right Method

Custom printing shirts comes down to three decorating methods, each built for a different job. Screen printing handles bold designs and large runs, direct-to-garment (DTG) excels at full-color artwork on small orders, and heat-transfer vinyl suits simple names and numbers. The right pick depends on your fabric, garment color, and how many shirts you need. Most print shops use all three daily, so the choice is about matching the method to the job, not finding one “best” option.

What Are The Main Custom Shirt Printing Methods?

Screen printing forces ink through a mesh stencil onto the fabric, one color at a time. It delivers bold, vibrant colors and excellent durability at scale, making it the go-to for team shirts, event wear, and any order over a dozen pieces. Vistaprint’s t-shirt printing guide notes the process suits designs with limited colors and crisp edges.

DTG works like a desktop inkjet printer but for fabric. The print head lays ink directly onto the shirt, which means full-color photographs and gradients reproduce beautifully without setup fees. The catch is speed: DTG runs slower and costs more per shirt than screen printing on large orders.

Heat-transfer vinyl and similar methods cut designs from colored film and press them onto the fabric with heat. This route shines for simple text, names, and numbers, especially on single shirts or tiny batches where screen printing setup would be wasteful.

Which Printing Method Fits Your Shirt Job?

Match the method to your order size and artwork complexity first, then confirm the fabric can handle it. The comparison below distills the practical differences.

Garment color and fabric type change the equation. DTG printing on dark shirts requires a pretreatment step so white ink adheres properly, while light shirts can often skip it. A 100% cotton shirt absorbs ink beautifully, but polyester blends need lower heat settings to avoid scorching or melting the fabric.

How Do You Prepare Artwork For T-Shirt Printing?

Good artwork prevents most print failures. Start with a file at least 300 DPI and a transparent background so the design sits cleanly on the shirt color. Vector files (PDF, SVG, AI, or EPS) are ideal for screen printing because they scale without losing sharpness, keeping text and edges crisp at any size.

Industry guidance consistently flags a few common mistakes: using low-resolution art pulled from the web, forgetting transparent backgrounds, leaving text un-outlined, and placing designs too high or too large. For placement, a centered chest print typically sits about 2.5 to 3 inches down from the collar, with left-chest prints running roughly 2.5 to 5 inches wide and tall.

Remember that screen colors rarely match printed fabric exactly. Order a proof before full production, especially for brand colors or skin tones.

What Does The Printing Process Actually Involve?

Each method has a distinct workflow, but all share the same three phases: prepare artwork, apply ink or film, then cure the result for durability.

On press, ink is pushed through the mesh with a squeegee held at a 10–15 degree angle on automatic presses. , locking the print into the fabric so it survives washing.

DTG replaces the screen with inkjet-style print heads that lay ink directly onto the garment. Dark shirts get a pretreatment spray before printing to help white ink bond, then the shirt cures under a heat press or conveyor dryer.

Heat transfer skips wet ink entirely. The design is cut from vinyl film, weeded of excess material, and pressed onto the shirt at high temperature and pressure for a set dwell time.

Proper curing is the durability gate for every method. Under-cured prints wash out or crack within a few cycles, so follow the manufacturer’s time and temperature specs exactly, and ventilate your workspace against ink and pretreatment fumes.
