How to Make Custom Shirts | From Home or Professional Print

For the full breakdown, see our best Custom Shirts guide.

The right way to make custom shirts depends on how many you need, how detailed the artwork is, and whether you want to do it yourself or send it out. A single shirt for a birthday gift calls for an iron-on transfer; a dozen for a team event makes screen printing or a print service the smarter call. The good news is that every route starts with the same two things: a good blank shirt and artwork that’s prepared for printing.

Artwork Prep That Actually Matters

Before you touch a shirt, your design file has to be print-ready. Garment printing shops routinely reject files that look fine on a phone screen but turn blurry on fabric. Following these file rules keeps your design sharp and avoids expensive do-overs.

• Use vector files (AI, EPS, SVG, or print-ready PDF) for logos, type, and simple graphics.
• Use 300 DPI at final print size for photos or textured art.
• Work in CMYK or Pantone color modes, not RGB, since RGB files print duller than they look on screen.
• Convert all text to outlines so fonts don’t substitute on another computer.
• Keep the background transparent unless you actually want a printed box.

That last point is the most common mistake: a white rectangle around your design creates a visible “sticker effect” on dark shirts. A transparent background keeps the print looking like part of the fabric. For insights on which shirts to buy, this guide to custom shirts covers the top-rated blanks and print-on-demand picks.

At-Home Iron-On Transfers

For a single shirt or small batches, iron-on transfer paper is the simplest hands-on method, and ironing it properly takes about ten minutes per shirt. The key is to follow the paper’s packaging directions, since light-fabric and dark-fabric papers work differently.

1. Print your design on the correct transfer paper for your shirt color. Mirror the image for light-fabric paper; for dark-fabric paper, keep the design face up.
2. Trim closely around your design to remove excess backing.
3. Preheat the iron with no steam, and place the shirt on a flat, hard surface.
4. Iron with firm, even pressure in small circles for the paper’s recommended time.
5. Let the transfer cool completely, then peel the backing gradually. Repress and re-peel if any part didn’t adhere.

Canon’s at-home shirt printing guide emphasizes that the exact heat setting and pressing time come from your transfer paper’s instructions, not a universal number. Skip the steam entirely, as moisture prevents the adhesive from bonding properly. The result is a shirt that holds up for casual wear, though not as rugged as professional printing.

Screen Printing or a Print Service

Screen printing is the professional standard for bulk orders and bold, long-lasting designs. The workflow starts with washing and drying the shirt, then placing cardboard inside the garment to prevent ink bleed-through. You position the stencil, pull ink across the screen with a squeegee at a 45-degree angle with consistent pressure, and finally heat-set the ink with a heat press or conveyor dryer at the manufacturer’s specified temperature and duration.

Screen printing suits simple, high-contrast designs in large quantities, but setup costs make it wasteful for a single shirt. That’s where a print-on-demand service becomes the practical middle ground. The standard service workflow is straightforward: design your artwork first, decide quantity and budget, choose a printer, upload your files, and check a proof before production begins. A proof catches color shifts and layout errors before they’re baked into fabric.

Choosing the Right Method

Match the method to your artwork detail, fabric type, and order size, and verify the file format, resolution, and color setup before ordering. If you’re ordering custom shirts through a service, the finishing choice matters too: a soft-hand print suits cotton, while a vinyl or screen print holds up better on performance fabrics.
