This guide covers various types of squeegees, covering materials, durometer values, shapes, and maintenance, along with practical tips and storage solutions.
Types of Squeegees
- Wooden Squeegees
- Aluminum Squeegees
- Modular Squeegees
Squeegee Materials
- Polyurethane Blades: Known for chemical resistance and durability, these blades retain elasticity and are favored in the industry.
- Handle Materials: Aluminum handles resist corrosion, essential in environments with inks and solvents.
Durometer Dynamics
- The durometer scale, ranging from 0 to 100, indicates hardness, with common ratings from 60 (soft) to 90 (hard). Triple-layer squeegees offer a balance of rigidity and flexibility, optimizing ink transfer.

Squeegee Layering
- Triple-Layer Squeegees: These consist of multiple layers with varying durometer ratings, providing an ideal balance of rigidity and flexibility. This design optimizes ink shear and deposit, making them versatile for different printing needs.
- Single and Double-Layer Squeegees: These can also vary in hardness and softness, and choosing the right configuration depends on the specific ink and printing technique used.
Exploring Squeegee Blade Profiles
Edge Geometry: Squeegee edges can be square, rounded, or beveled, influencing the amount and manner of ink deposit.
Colour Coding: Due to the lack of standardized color coding among manufacturers, a durometer gauge is necessary to achieve precise ink deposits for high-quality prints. See Pleiger Plastics Company USA vs. Trelleborg.
Maintenance Tips
- Cleaning: Use specialized solutions to remove ink without harming blades.
Squeegee Sharpener
Screen Printing Squeegee Washing Machine
Alternatively, a variety of tools are available to maintain or modify your squeegee, ensuring it stays in top condition.
Screen Printing Squeegee Washing Machine: A dedicated automatic machine for swift and thorough cleaning of your squeegee.
Knife Cutter: Ideal for precisely cutting the squeegee to your desired length.
Sharpening: Regular sharpening keeps edges crisp for clean prints.
Squeegee Corner Clipper: Utilized for rounding the corners of the squeegee, helping to prevent mesh wear.
Storage Solutions
Storage: Proper storage protects edges; hanging squeegees ensures safety and easy identification.
Effective Usage Techniques
- Printing Pressure: Avoid excessive pressure to prevent bending, which can compromise print quality.
- Angle and Speed: A 45-degree angle is optimal; however, adjustments may be needed based on ink and mesh types.
Eco-Friendly Options
Squeegees made from recycled materials or featuring replaceable blades help minimize waste.
Innovations
Ergonomic Designs: These reduce fatigue during high-volume printing.
Technological Advancements: Double-blade squeegees can improve printing speed and quality, but claims of significant production gains should be scrutinized.. Source
Cost Management
Budgeting for quality squeegees is essential for hobbyists and professionals. Understanding their complexity can enhance screen printing quality.
Pro Tips
For aluminum handles, grease screws to prevent seizing from moisture.
FAQs
Best Squeegee Handle?
Aluminum is recommended for durability and ease of cleaning.
Why Different Colors?
Colors indicate durometer; without a universal standard, manufacturer-specific codes prevail.
What squeegee shape works best for specific printing needs?
Rounded edges deposit more ink, while sharp edges provide precision.
How are Squeegees Sold?
Available in meters or rolls for cost efficiency.
Best Shape for Printing?
Round squeegees deposit more ink; sharp ones deposit less.
Durometer Meaning?
Indicates hardness; typical printer range is 65 to 90.
