Selecting the right squeegee for screen printing is essential to achieving high-quality prints. The type of squeegee you use affects ink application, durability, and overall efficiency, making it crucial to match your squeegee with the ink type—whether water-based or plastisol. Understanding the differences in materials, durometer, blade shape, and maintenance can help you optimize your printing process and extend the lifespan of your tools.
Material matters: rubber vs. polyurethane squeegee blades for water-based and plastisol inks
Squeegee material significantly influences ink application and durability. Rubber squeegee blades, while cost-effective, tend to wear out faster, especially when used with water-based inks that are more abrasive. Polyurethane squeegee blades, on the other hand, offer superior durability and are better suited for high-production environments. Water-based inks require a squeegee that can withstand moisture absorption without degrading quickly, making polyurethane the preferred choice. Plastisol inks, being thicker and less aggressive, work well with both rubber and polyurethane blades, though polyurethane provides longer-lasting performance.
Understanding squeegee durometer: how hardness affects water-based and plastisol prints
Squeegee durometer, or hardness level, determines how much ink is deposited onto the substrate. A soft (low-durometer) squeegee (60-70) is ideal for water-based inks because it allows more ink to pass through the screen, ensuring smooth coverage. Medium (70-80) durometer squeegees offer versatility, working well with both water-based and plastisol inks. A hard (80-90) squeegee is commonly used for plastisol printing, providing better control for detailed prints while reducing ink deposit thickness.
Choosing the right durometer is crucial to balancing ink flow, detail retention, and screen longevity.
Blade shapes explained: choosing the right edge for water-based and plastisol printing
Squeegee blade shape affects ink transfer and print consistency. A square-edged blade is the most common choice for plastisol ink, ensuring clean, even prints with minimal ink deposit. A rounded edge squeegee is ideal for water-based inks, as it allows more ink to pass through and prevents the ink from drying too quickly on the screen. Beveled-edge squeegees offer a middle ground, providing control while allowing moderate ink flow, making them suitable for specialty prints where precision is required. Selecting the right blade shape ensures optimal results based on your ink type and printing style.
Pressure and angle: how squeegee Technique Differs for Water-Based vs. Plastisol Inks
Proper technique is crucial when printing with different ink types. Water-based inks require a lighter touch with a more vertical squeegee angle (75-80 degrees) to prevent ink from flooding the screen and drying prematurely. Plastisol inks, being thicker, need more pressure with a slightly lower angle (60-75 degrees) to push the ink through the mesh effectively. In both cases, maintaining consistent pressure and angle ensures even prints, reduces ink waste, and prolongs the life of the screen.
Durability and maintenance: how water-based inks wear out squeegees faster than plastisol
Water-based inks are more abrasive and can cause squeegee blades to degrade faster than plastisol inks. Frequent exposure to moisture softens and warps the edges of rubber blades, reducing their effectiveness over time. Regularly rotating squeegees, cleaning them thoroughly after each use, and using sharpening tools to maintain blade edges can extend their lifespan. Plastisol-friendly squeegees experience less wear but still require periodic sharpening and proper storage to maintain peak performance.
Top squeegee brands for water-based and plastisol printing: a buyer’s guide
Choosing a high-quality squeegee brand ensures consistent print results and long-lasting durability. Some of the top brands include:
-
FIMOR: Known for its high-end polyurethane squeegees that provide exceptional durability and performance for both ink types.

Investing in reputable brands reduces the need for frequent replacements and ensures optimal printing results.
Manual vs. automatic press squeegees: do you need different squeegees for water-based and plastisol inks?
Manual and automatic screen printing require different considerations when selecting squeegees. For manual presses, softer squeegees with lower durometers help reduce strain and provide better ink flow control. Automatic presses, which apply consistent pressure and speed, work best with harder squeegees to maintain precision in high-volume production. Water-based inks require manual presses to use softer blades, whereas plastisol can be handled effectively with firmer options, whether in manual or automatic settings.
Eco-friendly squeegee options: sustainable choices for water-based ink printing
Sustainability is becoming a priority in the printing industry, and eco-friendly squeegee options are gaining popularity. Biodegradable and non-toxic squeegee blades made from recycled materials help reduce environmental impact. Some manufacturers now offer long-lasting squeegees that require less frequent replacement, minimizing waste. Additionally, using cleaning solutions with fewer harsh chemicals extends the lifespan of squeegees while reducing pollution.
Cost vs. performance: investing in the best squeegees for uour ink type
Balancing budget and performance is key when purchasing squeegees. Cheaper rubber squeegees may seem cost-effective initially but wear out faster, requiring more frequent replacements. High-end polyurethane squeegees, though more expensive, offer greater durability and precision, making them a better investment for long-term use. For businesses with high print volumes, investing in durable, high-quality squeegees reduces downtime and ensures consistent print quality.
Troubleshooting ink issues: when your squeegee is causing printing problems with water-based or plastisol inks
Incorrect squeegee selection can lead to printing problems such as ink bleeding, uneven coverage, or premature drying. If water-based ink dries too quickly, switching to a softer squeegee with a rounded edge can improve ink flow. For plastisol printing, inconsistent prints often result from using a squeegee that is too soft, requiring an adjustment to a firmer blade. Regular maintenance, sharpening, and adjusting pressure settings help resolve these issues and optimize printing results.
Conclusion
Choosing the right squeegee for water-based and plastisol inks is essential for achieving professional-quality prints. Understanding how material, durometer, blade shape, and technique affect ink application ensures consistency and efficiency. Regular maintenance and investing in durable squeegees help prolong their lifespan, reducing costs over time. Whether using a manual or automatic press, selecting the appropriate squeegee enhances print precision and streamlines the screen printing process. By considering these factors, screen printers can optimize their workflow and achieve superior print results.
