Screen Printing T-Shirts: A Diy Guide

Screen printing T-shirts is a fun and inexpensive way to express your individual style. It is a simple process that involves transferring a printed design onto a T-shirt using a chemical process called photo emulsion. To get started, you will need a design, a screen, ink, and a T-shirt. You can create your own screen using a canvas stretcher frame and mesh, or you can buy a ready-made screen from a craft store. Once you have your materials, you will need to create a stencil, prepare your screen, and then transfer the design onto your T-shirt using a squeegee. Finally, you will need to cure the print with heat to set the design. With a little time and effort, you can create unique and personalised T-shirts at home.

Choosing a design: Start with a simple black-and-white design, like a silhouette or lettering

When it comes to choosing a design for your screen-printed T-shirts, it's best to start with something simple, especially if this is your first time. A black-and-white design, like a silhouette or lettering, is a great option as it will be easier to transfer onto the screen and will give you more room to experiment with the screen printing technique.

If you're feeling artistic, you can draw your own design by hand. Just remember to use a thick black marker to outline your image and scan it to your computer. If you're not confident in your drawing skills, you can find images online and alter them using programs like Photoshop, Microsoft Word, or Microsoft PowerPoint. Remember, the image must be black-and-white in order to transfer the design onto the screen successfully.

Once you've selected your image, print it onto a clear transparency sheet. Make sure to double-check that your image is in black-and-white before printing. You may need to change the paper settings on your printer to accommodate the transparency sheet.

If you're creating a more complex design with multiple colours, you'll need to create multiple screens, each with a portion of your photo. This process will require some trial and error, so be prepared to experiment and have fun with it!

Keep in mind that the quality of your artwork will impact the final product. So, take your time to create a design that you're happy with and that will translate well onto your T-shirts.

Materials: You'll need a screen, fabric paint, emulsion, a squeegee, a craft knife, masking tape, and a plain cotton t-shirt

Screen printing your own t-shirts is a fun and inexpensive way to express your individual style. It's also a great way to transfer a printed design onto fabric. Here's a list of the materials you'll need to get started:

Materials:

• Screen: You can buy a ready-made screen from a craft store, or make your own using a canvas stretcher frame and mesh. Stretch the mesh over the frame and staple it firmly to the sides.
• Fabric paint: Choose non-toxic, water-based ink for fabric printing. You can find fabric paint at craft stores or online.
• Emulsion: Emulsion is a light-sensitive chemical that, when mixed with a sensitizer, hardens when exposed to UV light. This mixture is used to create a stencil on your screen.
• Squeegee: You'll need two squeegees—one to spread the emulsion over your screen, and another to pull the ink across your design when printing.
• Craft knife: Use a craft knife to cut out your design from a piece of paper or stencil paper.
• Masking tape: Place masking tape around the edges of your screen to prevent ink from seeping over the sides of your stencil.
• Plain cotton t-shirt: While you can screen print on most fabrics, a plain cotton t-shirt is the easiest option for beginners.

With these materials, you'll be well on your way to creating your own custom t-shirts at home. Remember to refer to online tutorials for detailed instructions on each step of the screen printing process.

Making a stencil: Draw your design on paper and cut it out. Alternatively, print your design onto a clear transparency sheet

Making a stencil is an important step in the screen printing process. Here's a detailed guide on two methods for creating stencils:

Drawing and Cutting Out a Design on Paper

This method is ideal for those who want to create a simple stencil by hand. Start by drawing your design on a piece of paper. If you're new to screen printing, it's best to choose a basic silhouette or a design with solid, dark lines. You can also print your design onto regular paper if you don't want to draw it by hand.

Once you have your design, carefully cut it out using a craft knife or a sharp pair of scissors. This will be your stencil, which you'll use to apply the ink to your T-shirt.

Printing Your Design Onto a Clear Transparency Sheet

If you want to create a more intricate design or prefer a digital approach, you can print your design onto a clear transparency sheet. First, ensure that your design is mirrored or reversed before printing, as this will ensure that it appears correctly on your T-shirt.

After printing, carefully cut out the design from the transparency sheet using a craft knife or a sharp pair of scissors. This method provides a more durable stencil and is suitable for those who want to create complex designs or print multiple copies.

Regardless of the method chosen, the stencil is a crucial component of the screen printing process. It allows you to apply ink to your T-shirt in a controlled manner, ensuring that your design is accurately transferred to the fabric.

Preparing the screen: Coat both sides of the screen with emulsion and leave to dry in a dark place

Preparing the screen is a crucial step in the screen printing process. Here's a detailed guide on how to do it:

Before you begin, ensure your screen is clean and free of any dust, lint, or particles. This step is important as it ensures that your emulsion coating will be smooth and bump-free. Once your screen is clean, you're ready to coat it with emulsion.

Coating the screen with emulsion:

• Work in a darkroom or a dimly lit room to avoid exposing the emulsion to light. Emulsion is light-sensitive, so it's crucial to work in controlled lighting conditions.
• Mix the emulsion according to the manufacturer's instructions. Different brands may have specific mixing instructions, so be sure to read the directions carefully.
• Using a squeegee, apply the emulsion to the screen. Coat both sides of the screen evenly and thinly. Work quickly and make sure you have a nice, smooth coat.
• Once the screen is coated, place it in a dark, dry place. You can use a closet or a room with no windows and cover any cracks that let in light. Alternatively, cover the frame with a thick, dark fabric if you need to transport it.
• Let the emulsion dry. Drying time can vary depending on the thickness of your coat, but it typically takes around 1-3 hours. You can speed up the drying process by using a fan set on low, pointed at the screen.

Once your screen is coated and dry, you're ready to move on to the next step of the screen printing process, which is exposing the emulsion to light and transferring your design. Remember to work quickly and efficiently when dealing with emulsion to avoid any accidental exposure to light.

Exposing the emulsion: Place your stencil on the screen and expose it to light to harden the emulsion

Exposing the emulsion is a critical step in the screen printing process. Here's a detailed guide on how to do it:

Prepare the Stencil and Screen:

Before exposing the emulsion, ensure you have a properly prepared stencil and screen. Create your stencil by cutting out your desired image onto regular or transparency paper. The image should be opaque, blocking all light from passing through. If using regular paper, you may need to double up the paper or colour it with a black marker to achieve the necessary opacity.

Next, prepare your screen by coating it with emulsion. The emulsion is light-sensitive, so this process should be done in a darkroom or a completely dark space to prevent premature exposure. Use a squeegee to apply a thin and even layer of emulsion to both sides of the screen. Once coated, let the screen dry. The drying time will vary depending on the emulsion and thickness of the coat, but it typically takes around one to three hours.

Place the Stencil:

Once the screen is dry, it's time to place your stencil. Position the screen on a black matte surface with the non-recessed side facing up. Carefully place your cut-out image or transfer paper onto the screen, ensuring it is in reverse. This means you should hold the image so that you're viewing it as it will appear on the T-shirt, and then flip it over before placing it on the screen.

Expose to Light:

Now, you're ready to expose the screen to light. You can use a lightbox or a regular lightbulb for this step. If using a lightbulb, a 150-watt incandescent bulb or a 20-watt LED bulb is recommended. Place the light so that it shines down onto the screen from a specified distance, as instructed by the emulsion manufacturer. The distance and exposure time will depend on the size of your screen, so refer to the emulsion's instructions.

During exposure, the light will harden the emulsion on the screen, except for the areas blocked by the stencil. After the allotted exposure time, simply wash the screen with lukewarm water, and the unexposed emulsion under the stencil will wash away, leaving your desired design on the screen.
