Whether you're rocking your favourite brand tee or walking around in a custom hoodie, chances are you've worn screen-printed clothing. It's one of the oldest and most reliable printing methods out there, and it's still going strong. But what actually goes into screen printing? How does it work, and why do so many brands swear by it?
Let’s take a deep dive into the art (and science) of screen printing.
🌟 What is Screen Printing?
Screen printing is a printing technique where ink is pushed through a mesh screen onto a surface—usually fabric—using a stencil. It's known for its vibrant colors, durability, and professional finish, especially for bulk printing.
Fun fact: Screen printing dates back to ancient China around 960 AD. Fast forward to today, it's a go-to for artists, apparel brands, and even fine art creators.
🧠 How Does Screen Printing Work?
At its core, screen printing is all about using a stencil (the screen) to apply layers of ink onto a surface. Sounds simple, right? Let's break it down.
🔧 1. Design Creation
Everything starts with your design.
• Your design is split by color. Each color will require its own screen.
• Software like Adobe Illustrator or Photoshop is used to prepare the artwork.
• The design is then printed onto a transparent film (like acetate) to use in the next step.
🧴 2. Screen Preparation
Now comes the “screen” in screen printing.
• A mesh screen (traditionally made of silk, now polyester) is coated with a light-sensitive emulsion.
• Once dry, the transparent film with your design is placed on the screen.
• The screen is then exposed to bright UV light.
Where the light hits, the emulsion hardens. Where the design blocks the light, the emulsion stays soft.
💦 3. Washing the Screen
After exposure, the screen is washed with water.
• The soft emulsion (the design area) washes away, creating a stencil.
• You’re left with a screen where ink can pass through only the design parts.
• Each color of the design will have its own screen prepared this way.
🖨️ 4. Setting Up the Screen for Printing
Once your screen is ready, it’s time to print.
• The screen is placed on a printing press over the item (usually a t-shirt).
• Ink is poured onto the top of the screen.
• A squeegee is used to pull the ink across the screen, forcing it through the mesh onto the material underneath.
• This step is repeated for each color, drying in between layers.
🔥 5. Curing the Ink
Once printed, the ink needs to be cured so it sets permanently.
• The garment is run through a dryer (around 320°F or 160°C).
• This ensures the ink bonds with the fabric and won’t wash out or crack.
🧵 Materials Used in Screen Printing
Here’s a list of essentials:
• Screens: Usually made of polyester mesh.
• Squeegees: Rubber blades used to push ink through the screen.
• Inks: Plastisol (most common), water-based, or discharge inks.
• Emulsion: Light-sensitive liquid for stencil-making.
• Dryers: For curing the final print.
• Press Machines: Manual or automatic, for holding screens and garments in place.
🎨 Why Choose Screen Printing?
✅ Durability: Prints last through countless washes.
✅ Vibrant Colors: Especially on dark fabrics.
✅ Cost-Effective for Bulk: The more you print, the cheaper it gets per piece.
✅ Versatile: Works on t-shirts, hoodies, tote bags, posters, and more.

🧼 Caring for Screen Printed Items
To make your print last:
• Wash inside out with cold water.
• Avoid bleach and harsh detergents.
• Tumble dry low or hang dry.
• Don’t iron directly on the print.
🚀 Wrapping It Up
Screen printing might seem old-school, but it’s stood the test of time for a reason. It delivers bold, long-lasting prints and is ideal for both artists and apparel brands. Whether you’re customizing merch for your business or creating wearable art, screen printing offers reliability, quality, and that classic printed look.
