What is screen printing on t-shirts?

Screen printing is a printing method that uses screens (or stencils) to transfer ink onto a textile surface, such as a t-shirt. This technique, used for decades, is renowned for its precision, durability, and ability to reproduce complex designs and vibrant colors.

The process begins with creating a screen, which is coated with a photosensitive emulsion. A positive film of the design is then exposed to light to transfer the pattern onto the screen. Once the screen is ready, ink is applied through it using a squeegee, creating a sharp and durable print.

The benefits of screen printing for t-shirts

• Exceptional durability: Screen prints can withstand numerous washes without fading or peeling.
• Versatility: Suitable for a wide variety of fabrics, colors, and designs, screen printing is ideal for both small and large volumes.
• Professional quality: The finishes are crisp, precise, and suitable for complex designs, even on dark fabrics.
• Cost-effectiveness: For large runs, screen printing is one of the most economical printing methods.
• Customization: Perfect for creating unique designs, whether for events, businesses, or fashion collections.

Key steps in textile screen printing

Screen printing on t-shirts follows a well-defined process that requires precision and attention to detail:

1. Design creation: Create or import your design using graphic design software.
2. Screen preparation: Apply a photosensitive emulsion to the screen and expose it to light with a positive film of the design.
3. Exposure: Use an exposure unit to fix the design onto the screen.
4. Printing: Place the t-shirt on the press and apply ink through the screen using a squeegee.
5. Curing: Pass the t-shirt through a drying tunnel to set the ink permanently.

Manual vs automatic screen printing: Which one to choose?

Manual screen printing

• Ideal for small runs, beginners, and custom projects.
• Affordable and easy-to-use equipment.
• Offers great flexibility in customization.

Automatic screen printing

• Perfect for large runs and professionals.
• Offers superior precision and speed.
• Reduces errors and increases productivity.

For versatile projects, a semi-automatic screen printing press is an excellent compromise. Brands like Tiflex and Serigraphie-Boutique offer models tailored to various needs.

Different types of screen printing inks

Choosing the right ink is crucial for achieving quality results. Here are the most common options:

• Plastisol ink: The most widely used, it offers vibrant and opaque colors. Ideal for dark fabrics.
• Water-based ink: More eco-friendly, it provides a soft and natural feel to the fabric. Perfect for lightweight designs.
• Discharge ink: Used to create a washed-out effect on dark fabrics. It removes the fabric's dye for a vintage look.
• Silicone ink: Ideal for stretchy fabrics like sportswear.

How to choose the right screen printing equipment?

For professional results, consider the following:

• Type of press: Manual for small runs, semi-automatic or automatic for large volumes.
• Number of colors: Choose a press that suits the complexity of your designs.
• Screen quality: Opt for aluminum screens for better durability.
• Accessories: Squeegee, exposure unit, drying tunnel, etc.
