Squeegees: A Critical Tool in Silkscreen Printing

Importance of the Squeegee

Among the tools used in silkscreen printing, the squeegee plays a pivotal role. It is responsible for effectively forcing ink through the screen and onto the substrate to be printed. Whether in hand-printing or machine operations, the quality of the squeegee directly impacts print quality.

Types and Specifications of Squeegees

Squeegees come in various materials and hardness levels, each suited to different applications within silkscreen printing. Standard brand squeegees are available in sizes up to a maximum length of 2.4 meters (8 feet). The blade can be custom-cut and sealed into the appropriate handle or molding. A strong coupling between the molding and blade ensures precision and control during printing. At UrekaGo, we also offer molding or blades separately for your convenience.

Squeegee Blades

The hardness of a squeegee blade is measured using a durometer scale:

- 50 to 60 Durometer: Indicates a soft squeegee, which leaves more ink on the surface.

- 60 to 70 Durometer: Represents a medium squeegee, offering a balance between deposit thickness and control.

- 70 to 80 Durometer: Denotes a hard squeegee, which results in thinner ink deposits.

Polyurethane squeegee blades have largely replaced rubber ones in areas where solvent resistance and durability are crucial, especially for long runs. They offer sharper edges and are recommended for machine printing. Polyurethane blades are available in translucent or colored options to indicate the manufacturer or hardness level.

Specifications of Polyurethane Squeegee Blades

- Color: Translucent or colored

- Size: Approximately 9.5 mm x 51 mm (3/8" x 2")

- Hardness: Ranges from 50 to 80 Durometer

- Length: Available in any length up to 3.6 meters (12 feet)

Polyurethane is versatile and comes in different shapes besides the standard square edge cut. Options include "D" cut, "S" cut, and rounded edges suitable for textile printing. These specialized cuts can enhance performance depending on the application.

Advantages of Polyurethane Squeegees

Polyurethane squeegees offer several advantages over traditional rubber blades:

- Resistance to "blade swelling," maintaining shape and performance.

- Lifespan that is 10 to 30 times longer than ordinary rubber.

- Reduced need for frequent sharpening.

- Lower pressure on the screen, reducing wear and tear.

- High tear resistance, ensuring longevity.
