Screen printing: all the materials and procedures you need
Fascinating yet easy to perform—even for beginners—screen printing is a printing technique that involves the use of a fabric matrix. It can be applied to customize surfaces such as wood, metal, fabric, plastic, glass, ceramics, and much more! Through this article, you can discover with Keygadgets all the steps to successfully create screen printing at home with great satisfaction and without making mistakes.
THE ORIGINS OF SCREEN PRINTING
This extraordinary printing technique, including the silkscreen transfer, was used to decorate the most precious fabrics as early as the 11th century in the Far East. However, scholars consider the Phoenicians to be the depositories of screen printing.To witness its debut in the world of modern art, we need to fast forward to the 1960s. With Andy Warhol, screen printing reached its peak of popularity. The most famous screen print of all time? Undoubtedly the iconic face of Marilyn Monroe!
In no time, screen printing spread to the so-called "underground" circles, becoming the preferred technique for creating posters, flyers, and t-shirts, thanks to its extreme simplicity of execution.
Screen printing materials: here's what you need
Unlike other printing techniques—such as lithography and woodcutting, which often require complex equipment and materials—screen printing can be done at home with minimal expense and without requiring special skills. Here is everything you need to create your own home screen printing studio.
- A frame—either wood or aluminum
- A squeegee
- Photosensitive emulsion
- Emulsion remover solvent
- An emulsion spreading tray
- Ink or acrylic paints
- Thinner
- A screen printing lamp
- Some sponges, including one abrasive sponge to remove residue from emulsion and ink
- A spray bottle
- Adhesive tape
- Acetate sheets for printing
While some of these tools may be familiar—being commonly used—others might be entirely new to you, especially if you have never performed screen printing before. Continue reading to discover all the steps and information needed to create your first screen print at home.
CREATE THE ENVIRONMENT
Step 1: Apply the emulsion to the frame
- Pour a generous amount of emulsion into the tray until it's half full. Any unused excess can be recovered and used for another print.
- Position the frame vertically and hold it firmly against a wall.
- Place the emulsion spreading tray against the screen, leaving a 2 cm margin from the frame.
- Tilt the tray and spread the emulsion across the entire screen, starting from the bottom and moving upward.
- Repeat the same process on the opposite side of the frame.
- Now, let the frame dry, away from direct light.
Step 2: Prepare the exposure unit
If you wish to print a design—whether simple or complex—you'll need to get special transparent sheets on which to print the design in black using a regular laser printer. Remember that anything etched onto the frame corresponds to the areas where, during exposure, light will not pass. For this reason, the design should be perfectly black. Here’s how to proceed:
- Place the frame, with the side to be etched facing up, on a piece of black fabric, and position the screen printing lamp about 65 cm away. O
- Next, place the acetate sheet on the frame, making sure the print touches the screen. For a more precise result, place a glass plate on the frame.
Step 3: Expose the frame
Turn on the lamp to expose the frame. Exposure times vary depending on factors like the strength of the light used. If you are using a specific lamp, follow the manufacturer’s instructions.
If you are using a standard halogen spotlight, keep in mind that a 500-watt halogen light positioned about 65 cm away from an A3-sized frame requires an exposure time of around 8 minutes.
Step 4: Remove the exposed areas of the frame
After completing the exposure, place the frame in the tub, making sure to wet both sides thoroughly. After a few minutes, the design will begin to appear. This is the time to remove the excess emulsion using a sponge. Once it’s well cleaned, let the frame dry away from direct heat sources, ensuring the back is facing up.
Step 5: Mask the frame and prepare the ink
Once dried, cover the inner side of the frame, where you’ll pour the ink, with adhesive tape. This will protect the non-emulsified part of the screen, near the frame. To prepare the ink, mix 40% acrylic ink (water-based) with 60% thinner.
Step 6: Perform the printing
It’s finally time to place the surface you wish to print on under the frame! To start, pour the previously prepared ink onto the edge of the frame, then spread it across the surface using the squeegee, while keeping the frame slightly elevated.
Now lower the frame and move the squeegee from top to bottom. This will transfer the design onto the chosen surface.
Step 7: Clean the frame
After completing the prints, you can remove the excess ink from the frame and the squeegee, so they can be reused for future work. To clean the frame with water, you can use a spray bottle. First, remove the adhesive tape and place the frame in the tub. After wetting it, apply the emulsion remover solvent.
Wait a few minutes, then rinse the frame under running water and remove any remaining emulsion using a special abrasive sponge.
