Screen Printing for Bulk Custom T-Shirts

What screen printing actually is

Screen printing is the oldest and still the most-used technique in custom apparel, and for good reason: it lays down a thick, opaque film of ink that bonds into the fabric and survives years of washing. The process hasn't changed in principle for decades. You build a separate stencil for every colour in a design, push specialised plastisol or water-based ink through the open areas of a fine mesh screen, and heat-cure the result so it sets permanently. What has changed is the precision — modern auto presses, computer-cut films and Pantone-matched inks let us reproduce a brand's exact colour run after run, shirt after shirt.

If you've ever owned a band tee, a sporting club jersey or a corporate uniform that still looks sharp after a hundred washes, odds are it was screen printed. That longevity is the whole point. Where a transfer sits on top of the cloth, screen-printed ink is pushed into the weave and cured into it, so it flexes and stretches with the garment instead of cracking off it.

How the process works, step by step

The interactive diagram above walks through the four core stages. Here's what's happening at each one in plain English.

1. Burning the screen (making the stencil)

We start with a wooden or aluminium frame stretched with a tight polyester mesh — finer mesh for detailed art, coarser mesh for heavy ink deposits like athletic numbers. The mesh is coated with a light-sensitive emulsion and dried in the dark. Your artwork, separated into one film positive per colour, is laid on top and the screen is exposed to a strong UV light. Wherever the black artwork blocks the light, the emulsion stays soft and washes out; everywhere else it hardens. The result is a stencil: open mesh exactly in the shape of your design, sealed everywhere else. This is the “burn,” and it's why screen printing carries a one-off setup charge per colour, per screen.

2. Registration and the first colour

Each screen is clamped into the press and aligned — “registered” — so every colour lands in exactly the right spot relative to the others. The shirt sits on a platen beneath the screen. A printer floods ink across the top of the mesh, then drags a rubber-bladed squeegee across it under pressure. The squeegee forces ink through the open stencil areas and onto the fabric below, and lifts cleanly everywhere the emulsion has sealed the mesh. One pull, one colour, laid down crisp and opaque.

3. Building up the colour layers

Multi-colour designs are printed one screen at a time. On dark garments a white “underbase” is usually printed first and flash-cured so the colours on top read as bright and true rather than dull. Each subsequent colour is registered to the last, so a two-, three- or eight-colour design is really a sequence of perfectly aligned single-colour prints stacked on the same shirt. Tight registration is the craft of the trade — get it right and the design looks like a single clean image.

4. Curing

Ink isn't permanent until it's cured. The printed garment passes through a conveyor dryer that heats plastisol ink to around 160°C, the point at which it fully cross-links and bonds to the fibres. A properly cured print won't crack, peel or wash out — under-curing is the single most common cause of a print failing early, which is why a careful printer matters more than a cheap one.

When screen printing is the right call

Screen printing earns its keep in three situations. The first is volume. The labour and setup cost of burning screens is fixed, so the more shirts you print from those screens, the less that cost matters per piece. A 25-shirt run carries the same setup as a 500-shirt run — but spread across 500 it's almost invisible. This is why screen printing is unbeatable on price once you're past a couple of dozen units, and why every other method eventually loses to it on a big order.

The second is bold, solid colour. Spot colours — a clean two-colour club logo, a slab of brand red, white text on a black hoodie — are exactly what screens were built for. The ink film is thick and saturated in a way no inkjet or transfer fully matches, especially on dark garments. If your design lives in a handful of flat, defined colours rather than photographic gradients, screen printing will out-pop everything else.

The third is durability. For workwear, hospitality uniforms, club merch and anything that gets washed weekly, a cured screen print rated for 50+ washes is the safe choice. It's the method we reach for when a garment has to look good for seasons, not just a season.

Who it's for in the real world

Screen printing is the default for 25–10,000+ pieces, bold spot-colour designs, team & event bulk runs. In practice that's the footy and netball club ordering 60 training tees, the brewery doing a 300-shirt merch drop, the construction firm kitting out 150 crew in branded hi-vis-friendly cotton, the music festival printing thousands of event tees, and the school P&C running a fundraiser uniform. If a group of people all need the same design and there's more than a couple of dozen of them, screen printing is almost always the answer.

It's a poor fit for the opposite end: a single one-off, a personalised name-and-number on each shirt, or a full-colour photographic image with subtle gradients. For those, direct-to-garment or a digital transfer will serve you far better — and we'll happily steer you there rather than burn screens you don't need.

The cost logic — why per-unit price falls with volume

Screen printing pricing has two parts, and understanding them is the key to getting the best value. First is the setup: a one-off charge per colour to burn each screen and register the press. A one-colour design is the cheapest to set up; an eight-colour design needs eight screens and eight registrations. Second is the print run itself, charged per garment.

Because the setup is fixed regardless of quantity, the per-shirt cost drops sharply as the order grows. Order 25 shirts and each one carries a meaningful slice of the setup. Order 250 and that same setup is divided ten ways further, so the price per shirt can fall well below the $9.95 starting point. The widget further down lets you slide the quantity and watch the indicative per-shirt price fall — it's the clearest illustration of why screen printing rewards bigger orders. Two practical tips: keep your colour count tight to keep setup low, and order in one batch rather than several small ones so you only pay setup once.

Inks, fabrics and specialty effects

Most of our screen printing uses plastisol ink — durable, vivid and forgiving — though water-based and discharge inks are available when you want a soft, almost-printless hand feel that sinks into the cotton. Cotton is the ideal canvas because it takes ink beautifully and cures cleanly; cotton best; blends fine, with the right ink and additives.

The technique also opens up effects no transfer can touch. Metallic and foil inks add shine, puff additive makes the ink rise into a raised 3D texture, high-density ink creates a sharp embossed edge, and glow-in-the-dark and reflective inks suit event and safety gear. Because every colour is its own screen, mixing a specialty ink into one layer of a design is straightforward. And every colour can be Pantone-matched, so your brand red is the same brand red on the first shirt and the ten-thousandth.

Australian context

Everything we screen print is produced, printed and owned right here in Australia, with Australia-wide shipping. That matters for lead times — you're not waiting on an overseas freight window — and it matters for the climate. Tougher Australian sun and frequent washing are exactly the conditions a cured screen print is built to handle, which is why it remains the go-to for sporting clubs, tradies, hospitality venues and events from Perth to the east coast.
