Screen printing squeegee blade 9mm 75 Shore A

The screen printing squeegee blade is mounted in a squeegee holder and forces ink through the mesh openings in the image areas of the stencil onto the substrate.

With a thickness of 9 mm and a hardness of 75 Shore A, this product is suitable for jobs requiring a combination of blade flexibility and controlled ink deposition. It is an option to consider for general textile and graphic screen printing when a balance between ink coverage and image definition is required.

Key Features

75 Shore A Hardness – Balancing Flexibility and Rigidity

75 Shore A falls within the medium-hardness range commonly used in screen printing. Lawson’s guidelines identify 70–75 Shore A as a popular range for general printing applications.

When comparing blades of the same material grade, dimensions and mounting configuration, a 75 Shore A blade is generally harder than a 70 Shore A blade and more flexible than an 80 Shore A blade. This intermediate characteristic helps operators select a degree of blade flex suited to ink transfer and image reproduction requirements.

Helps Balance Ink Deposition and Detail Definition

Squeegee hardness affects the amount of ink deposited onto the substrate. Under otherwise equivalent conditions, softer blades generally deposit more ink, while harder blades tend to deposit less.

Based on this principle, 75 Shore A can be considered when a balance between ink deposition and image definition is required. However, the actual ink film thickness also depends on mesh count, stencil thickness, ink properties, squeegee angle and pressure.

9 mm Thickness – Supports Blade Rigidity During Printing

The 9 mm thickness contributes to blade rigidity. To maintain stable performance, use a compatible blade holder and adjust the length of blade protruding from the holder appropriately.

Durability during continuous printing also depends on material quality, chemical resistance, squeegee pressure, and cleaning and maintenance practices.

Suitable for General Textile and Graphic Screen Printing

A 75 Shore A squeegee blade can be used for textile printing with plastisol, water-based and discharge inks. In graphic screen printing, this hardness can be used for spot colors and tonal gradients. These applications provide general guidance for the 75 Shore A hardness level and must be considered alongside the properties of the specific blade material grade.

Technical Specifications

Screen Printing Applications

▫ Textile and garment printing: Suitable for designs requiring a balance between ink coverage and detail reproduction.

▫ Graphic screen printing: An option for spot colors, text, logos and tonal gradients.

▫ Fine-detail and halftone printing: Supports jobs requiring controlled ink deposition when combined with suitable mesh and stencil specifications.

▫ Use with various ink systems: Can be considered for plastisol, water-based, UV-curable and solvent-based inks, provided the blade material meets the required chemical resistance.

Compatibility note: A hardness of 75 Shore A does not, by itself, determine resistance to inks or solvents. Check the specifications of the exact blade material grade before use.

Selection and Use Guidelines

▫ Select the appropriate hardness: Run print trials to assess coverage, detail definition and ink deposition before production.

▫ Use a correctly sized holder: Select a handle or blade holder suitable for a 9 mm thick blade. Avoid forcing the blade into the holder or clamping it unevenly.

▫ Adjust printing parameters: Coordinate squeegee angle, pressure and speed. Avoid excessive pressure that causes the blade to flex too much.

▫ Inspect the printing edge: Ensure that the contact edge is free from wear, nicks and deformation.

▫ Check ink compatibility: Confirm chemical resistance before use with UV-curable inks, solvent-based inks and specialized cleaning agents.

Cleaning and Storage

▫ Remove excess ink and clean the blade with a suitable cleaning agent after use.

▫ Allow the blade to dry and recover after chemical exposure before reuse or sharpening.

▫ Sharpen only when the blade is dry and the material is suitable for reconditioning by sharpening.

▫ Store away from direct sunlight and heat sources, and avoid conditions that bend the blade or place pressure on the printing edge.

▫ Rotate squeegee blades during continuous production to allow time for rest and inspection.

Proper cleaning, printing-edge maintenance and adequate recovery time are manufacturer-recommended practices that help protect the blade and support consistent print quality.
