How T-shirt Manufacturers Handle Screen Printing, DTG, and Embroidery
Our whole family cosplays, and we make our costumes at home, so I have a real appreciation for what it takes to get a design onto fabric. T-shirt manufacturers deal with that on a much bigger scale. This post explains the three main methods in plain terms. If you’ve ever wondered why one shirt feels different from another, this is a great place to start.
Getting a design onto fabric is never as simple as the software makes it look. In the back of a real T-shirt manufacturers facility, it’s a constant battle against humidity, ink viscosity and machine tension. Whether a shop is pumping out thousands of units or one of the hoodie manufacturers is handling a premium streetwear drop, the process is usually a lot more hands-on and prone to headaches than most people realize.
Screen printing, DTG and embroidery are the big three, but they aren’t interchangeable. Each one changes the “hand” of the fabric and the cost of the run in very different ways.
Screen Printing: The Heavy Lifter
If there is a massive stack of shirts to get through, screen printing is the only way to go. It’s an old-school process that relies on physics. You aren’t just printing; you’re forcing thick ink through a mesh stencil.
The setup is where all the work happens. A tech has to coat screens in emulsion, burn the image using a light table and then wash out the excess to leave a crisp stencil. If the design has four colors, that means four different screens, four different ink mixes and four separate stations on the press.
On the production line, the “registration” has to be perfect. If one screen is off by even a millimeter, the whole batch looks like a blurry mess. Once the ink hits the fabric, the shirts head into a long conveyor dryer. This is the part people miss: the ink has to reach a specific temperature (usually around 320 degrees Fahrenheit) to cure. If the dryer isn’t calibrated right, that logo is going to peel off in the first wash. It’s a messy, loud and sweaty process, but it produces the most durable finish you can get.
DTG: The Digital Compromise
Direct-to-garment (DTG) printing changed the game for small brands that can’t afford the setup fees of screen printing. It’s essentially a massive inkjet printer that uses specialized textile inks.
But DTG isn’t “plug and play.” If you just spray ink onto a dry shirt, it’ll look dull and wash right out. The fabric has to be pre-treated with a chemical solution first. This acts like a primer. Most T-shirt manufacturing shops have a separate machine just for spraying this “glue” onto the shirts before they ever touch the printer.
The real struggle with DTG is white ink. Since white ink is thicker and contains titanium dioxide, it tends to clog the print heads if the machine isn’t used every single day. For a Hoodie Manufacturers run, DTG is great for high-detail photos or gradients that a screen just can’t catch. It feels softer on the chest because the ink is thinner, but you lose that “pop” and longevity that you get from traditional printing.
Embroidery: The “Value Add” Method
Embroidery is a completely different beast because it doesn’t use chemicals or inks; it uses needles and thread. This is where most cut and sew manufacturers shine, especially for hoodies or heavyweight tees, where you want a premium feel.
Everything lives or dies by the “digitized” file. You can’t just use a standard logo file. A digitizer has to tell the machine exactly where every needle should drop, the stitch density and the “underlay,” which is the foundation stitching that keeps the logo from sinking into the fabric.
When the machines start running, the main enemy is “puckering.” If the tension on the thread is too tight, or if the fabric is too thin, the shirt will bunch up around the logo. Manufacturers use a “stabilizer” or “backing,” which is a piece of non-woven material behind the design, to keep the fabric flat. It’s a slow process compared to printing, but it adds a physical dimension to the garment that instantly makes it feel more expensive.
The Reality of the Floor
Choosing a method isn’t just about the art; it’s about the fabric. A thin 120 gsm jersey tee can’t handle a heavy 10,000-stitch embroidery logo without sagging. Likewise, a fuzzy fleece hoodie might “eat” a DTG print, making it look blurry because the ink can’t settle on a flat surface.
Professional manufacturing is about knowing these limitations before the machines start moving. It’s about checking the ink traps, testing the thread tension and making sure the dryer is hot enough. Most of the time, the “perfect” choice is a compromise between the client’s vision and what the equipment can actually handle without ruining the blank.
