The squeegee is one of the most important tools in screen printing. This simple yet essential tool is responsible for evenly distributing ink through the screen, ensuring sharp and high-quality prints. However, not all squeegees are the same: the choice of handle material, blade hardness, and other features can significantly impact the final result. In this guide, we’ll explore the differences between squeegees with wooden and aluminum handles, how to choose blade hardness, and much more.

What is a Squeegee?

Definition and Function

The squeegee consists of two main parts: the handle and the blade. The handle, made of wood or aluminum, provides a comfortable and stable grip, while the blade, made of rubber or polyurethane, is responsible for distributing the ink. Choosing the right squeegee depends on the type of work, the material to be printed, and personal preferences.

Blade Materials

The squeegee blade can be made of:

  • Natural Rubber: Ideal for water-based inks, it offers good flexibility but may wear out faster.
  • Polyurethane: More durable and resistant, it’s suitable for plastisol inks and solvents. It provides greater precision in ink distribution.

Differences Between Wooden and Aluminum Handles

Wooden Handle

The wooden handle is the traditional choice for squeegees. Here are its pros and cons:

  • Advantages:
    • Lightweight and easy to handle.
    • More affordable than aluminum models.
    • Ideal for occasional or hobby projects.
  • Disadvantages:
    • Less resistant to wear and moisture.
    • May warp over time if not stored properly.

Aluminum Handle

The aluminum handle is the preferred choice for professionals. Here’s why:

  • Advantages:
    • Extremely durable and long-lasting.
    • Easy to clean and sanitize.
    • Ideal for intensive use and professional projects.
  • Disadvantages:
    • More expensive than wooden models.
    • Slightly heavier, requiring more precision during use.
If you’re a beginner or work on small projects, a squeegee with a wooden handle might be sufficient. However, for professional or intensive use, the aluminum handle is the best choice.

Blade Hardness: How to Choose

What Does Blade Hardness Mean?

Blade hardness is measured in Shore (e.g., 70 Shore, 80 Shore) and indicates how flexible or rigid the blade is. A softer blade (70-75 Shore) is ideal for fine details and fluid inks, while a harder blade (80-90 Shore) is suitable for large coverage areas and thick inks.

Choosing the Right Hardness

  • 70-75 Shore: Perfect for detailed prints on lightweight fabrics or paper. Ideal for water-based inks.
  • 80 Shore: Versatile, suitable for most screen printing projects, including heavy fabrics and plastisol inks.
  • 85-90 Shore: Recommended for large print areas and dense inks. Offers greater resistance and durability.

Practical Tip

If you’re unsure about the hardness to choose, start with an 80 Shore blade. It’s a versatile option that fits most printing needs.

The choice of blade hardness depends on the type of work and the ink used. Experiment with different hardness levels to find the one that best suits your needs.

How to Use a Squeegee

1. Preparing the Screen

Ensure the screen is properly prepared with photo emulsion and that the design has been exposed to UV light. Place the screen over the material to be printed.

2. Applying the Ink

Pour a sufficient amount of ink onto the screen. Use the squeegee to spread the ink evenly, applying constant pressure and angling the blade at about 45 degrees to the screen.

3. Transferring the Design

With a smooth motion, drag the squeegee across the screen, allowing the ink to pass through the mesh and transfer the design onto the surface below.

Squeegee Maintenance

Cleaning

After each use, thoroughly clean the squeegee blade with a solvent suitable for the type of ink used. This prevents residue buildup and extends the tool’s lifespan.

Storage

Store the squeegee in a dry place away from heat sources. Avoid bending or damaging the blade during storage.

Conclusion

The squeegee is an indispensable tool for anyone involved in screen printing. Choosing the right squeegee, with the appropriate handle and blade hardness, can make the difference between a perfect print and a disappointing one. Whether you’re a beginner or a professional, investing in a high-quality squeegee is essential for achieving excellent results.
