I Screen Printed My First T-Shirt Using a $20 Kit from Amazon
The Embroidery Hoop and the Squeegee
I wanted to try screen printing but was intimidated by the expensive equipment. I bought a cheap, $20 beginner’s kit on Amazon. It came with a small screen, a squeegee, and a bottle of photo emulsion. I was sure it would be a toy. But I followed the instructions, burned my design onto the screen using the sun, and pulled my first print. The result was a surprisingly crisp, clean, and professional-looking print on a t-shirt. It was an amazing and empowering introduction to the craft.
The “Photo Emulsion” Method for Creating a Professional Stencil
The Magic of the Light-Hardened Liquid
I thought creating a screen printing stencil was a difficult, hand-cut process. Then I learned about “photo emulsion.” It’s a light-sensitive liquid that you coat your screen with. You then place a transparency of your design on the screen and expose it to a bright light. The light hardens the emulsion everywhere except where your black design is blocking the light. You then just wash the screen, and the unhardened emulsion rinses away, leaving a perfect, incredibly detailed stencil of your design. It feels like a magic trick.
How to Get a Perfect, Crisp Print Every Time (The “Squeegee Angle” Secret)
The 45-Degree Angle of Attack
My first few screen prints were blurry and had thick, uneven ink. I was holding my squeegee almost vertically. An experienced printer showed me the secret: the “squeegee angle.” The correct angle for pulling a print is a 45-degree angle. This angle allows the sharp edge of the squeegee to shear the ink cleanly off the screen, leaving behind just the right amount of ink in the stencil. This one, simple adjustment in my technique instantly made my prints sharp, crisp, and professional.
I Set Up a Multi-Color Screen Printing Press in My Garage
The Jiffy Hinge Press
I wanted to print t-shirts with more than one color, which requires perfect “registration.” I couldn’t afford a real printing press. I built my own for under $20 using two “Jiffy hinges” from an art supply store. These are special hinges that you clamp to a table. You clamp your screen into the hinges. This allows you to lift the screen up and down in the exact same spot every single time. It’s a simple, cheap, and brilliant way to create a functional, single-color printing press.
How to Clean Your Screen So You Can Reuse It Forever
The Emulsion Remover and the Power Washer
After I was done with a print run, I wanted to reuse my screen for a new design. I learned that you need a special chemical called “emulsion remover.” After cleaning all the ink from the screen, you spray on the remover and let it sit. It softens the hardened emulsion stencil. The secret to getting it all out is a pressure washer. The high-pressure water blasts the softened emulsion out of the fine mesh of the screen, leaving you with a perfectly clean, ghost-free screen that is ready for a new stencil.
The Difference Between Plastisol and Water-Based Ink
The Feel on the Shirt
There are two main types of screen printing ink. “Plastisol” ink is the industry standard. It’s a plastic-based ink that is very opaque and easy to use, but it sits on top of the fabric and has a thick, rubbery feel. “Water-based” ink is thinner and a bit more difficult to work with, but it soaks into the fibers of the fabric. The final print is incredibly soft and breathable, with almost no “hand feel” at all. One is a durable, vibrant coating; the other is a soft, integrated dye.
Stop Using a Heat Gun: How to Cure Your Ink So It Never Washes Out
The Flash Dryer is Your Friend
I was curing my plastisol ink prints with a heat gun. It was slow, and the results were inconsistent; some of my shirts would wash out. I learned that the ink needs to reach a specific temperature (usually around 320°F) to properly “cure.” I invested in a cheap “flash dryer,” the kind used by professional printers. It’s a simple, infrared heating element on a stand. It provides a wide, even heat that cures the entire print perfectly in about 30 seconds. My prints are now 100% permanent and wash-proof.
I Printed on a Tote Bag and Sold It on Etsy
The Walking Billboard
I had gotten pretty good at screen printing. I decided to try and sell my work. I bought a pack of cheap, blank canvas tote bags. I printed one of my cool, original designs on them. I took some nice photos and listed them on Etsy. To my surprise, they started to sell. It was an incredible feeling to see people in my own town walking around with a tote bag that I had designed and printed in my own garage. It was a walking advertisement for my art.
The Easiest Way to Register Your Colors for a Multi-Layer Print
The Transparency and the T-Square
I was struggling to line up my different color layers for a multi-color print. I learned a simple registration trick. I printed out my registration marks and my first color layer onto a piece of transparent film. I would use this to get my first screen perfectly aligned on my printing platen. Then, to line up the second color, I would just lay the transparency over my wet, first-color print, and then I would lower my second screen until the registration marks on the screen lined up perfectly with the marks on the transparency.
The Most Common Screen Printing Problem and How to Fix It
The Off-Contact Solution
My prints were blurry and splotchy. I was printing with my screen lying flat on the t-shirt. This was wrong. I learned the most important concept in screen printing: “off-contact.” You need to have a small gap, about the thickness of a coin, between your screen and your t-shirt. This allows the screen to snap back up off the shirt immediately after the squeegee passes, leaving behind a sharp, clean print instead of a smudged mess. You can achieve this by simply taping a coin to the four corners of your screen.
