Screen printing squeegee blade 7mm 70 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 70 Shore A, this product is suitable for jobs requiring a flexible blade with sufficient rigidity to control ink transfer. It is an option to consider for manual printing and small-scale production when a balance between ink deposition, coverage and image definition is required.

Key Features

70 Shore A Hardness – Balancing Flexibility and Pressure Transmission

70 Shore A falls within the medium-hardness range and suits many general printing jobs. The blade combines the ability to flex against the screen mesh with the rigidity needed to transmit pressure and control ink.

7 mm Thickness – Flexibility During Operation

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. This characteristic is useful when flexibility is required. Adjust pressure and blade protrusion appropriately.

Helps Balance Ink Deposition and Detail Reproduction

Medium hardness is suitable for jobs requiring an appropriate ink deposit and clear image reproduction. Coverage, ink film thickness and detail reproduction also depend on the mesh, stencil, ink properties and operating parameters.

Suitable for Manual Printing and Small-Scale Production

The blade can be used with a compatible manual squeegee handle for sample printing, short runs and jobs requiring flexible control of the printing stroke. When used on a printing press, check the blade holder and adjust operating parameters to suit the printing requirements.

Suitable for Various General Printing Jobs

70 Shore A is a versatile hardness for many screen printing applications. It can be considered for text, logos, solid color areas and general designs requiring a combination of ink transfer and image control.

Technical Specifications

Screen Printing Applications

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

▫ Graphic screen printing: An option for text, logos, solid color areas and designs with moderate detail requirements.

▫ Manual and sample printing: Suitable for short runs, color trials and jobs requiring adjustments to the printing stroke for each design.

▫ Machine printing: Use when the blade holder accommodates the 7 mm thickness and operating parameters are appropriate for the blade.

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

Compatibility note: A hardness of 70 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 surface.

▫ 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 printing 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.
