Screen printing squeegee blade 7mm 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 7 mm and a hardness of 75 Shore A, this product is suitable for jobs requiring a combination of blade flexibility and controlled ink deposition. Selecting the appropriate dimensions, holder and operating parameters helps meet general textile and graphic screen printing requirements.

Key Features

75 Shore A Hardness – Balancing Flexibility and Rigidity

75 Shore A falls within the medium-hardness range. When comparing blades of the same material grade, dimensions and mounting configuration, it is generally harder than 70 Shore A and more flexible than 80 Shore A, making it suitable for various printing jobs.

7 mm Thickness – Flexibility During the Printing Stroke

Compared with a 9 mm thick blade of the same material and hardness, mounted in the same way, a 7 mm blade generally flexes more readily. Adjust blade protrusion and pressure to maintain the appropriate working angle.

Helps Balance Ink Deposition and Detail Reproduction

Trelleborg’s guidelines recommend the 70–75 Shore A range for a variety of mesh and ink combinations, balancing ink transfer with detail control. Actual print quality also depends on the stencil, printing edge and printing parameters.

Suitable for Textile and Graphic Screen Printing

Murakami’s guidelines recommend 75 Shore A squeegees 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. Check the compatibility of the specific blade material grade.

Use with Compatible Manual Holders or Printing Presses

The 7 mm blade must be fitted in a compatible handle or blade holder. For machine printing, select the printing speed according to actual blade flex, pressure and image requirements. Blade thickness alone does not determine operating speed.

Technical Specifications

Screen Printing Applications

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

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

▫ Manual screen printing: Use with a compatible squeegee handle and adjust the angle and pressure to suit the job.

▫ Machine printing: Can be used when the blade holder accommodates the 7 mm thickness and operating parameters are adjusted appropriately.

▫ 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 correct blade holder: Ensure that the holder accommodates the 7 mm thickness and grips the blade securely and evenly along its entire length.

▫ Adjust blade protrusion: Avoid excessive protrusion, which increases blade flex and affects the working angle and ink deposition.

▫ Coordinate printing parameters: Adjust squeegee angle, pressure and speed according to the mesh, stencil, ink and substrate.

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

▫ Run print trials before production: Assess coverage, detail definition and ink film uniformity to finalize operating parameters.

Cleaning and Storage

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

▫ Avoid prolonged soaking in solvents or the use of highly aggressive chemicals.

▫ 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 in a cool, dry place away from direct sunlight and heat sources. 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.

Appropriate cleaning, printing-edge maintenance and adequate recovery time help protect the blade and support consistent print quality.
