Screen printing squeegee blade 9mm 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 9 mm and a hardness of 70 Shore A, this product is suitable for jobs requiring moderate blade flexibility and sufficient rigidity for the printing stroke. This hardness is widely used in general screen printing applications, helping operators balance ink deposition and image definition.

Key Features

70 Shore A Hardness – Flexibility for Various Printing Jobs

The 70 Shore A blade has medium hardness, allowing moderate flex when contacting the screen mesh. It is a popular choice for many general screen printing jobs.

Supports Ink Transfer and Color Reproduction

Under comparable printing conditions, a 70 Shore A blade generally transfers more ink through the mesh than a harder blade. This characteristic helps produce an ink deposit with coverage and color suited to the printing requirements.

Balances Ink Deposition and Image Definition

The 70 Shore A blade is suitable for printing text, logos and general designs. Combining the appropriate mesh count, stencil thickness and squeegee pressure helps control ink deposition while maintaining clearly defined lines.

9 mm Thickness – Supports Blade Rigidity During Printing

The 9 mm thickness contributes to blade rigidity during printing. Use a compatible blade holder and adjust the length of blade protruding from the holder to achieve the appropriate degree of flex.

Technical Specifications

Screen Printing Applications

▫ Textile and garment printing: Suitable for general designs requiring a balance between ink coverage and image definition.

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

▫ Manual and machine printing: Use with a compatible holder and adjust settings to suit operating conditions.

▫ 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 chemically aggressive ink systems or chemicals, particularly certain UV-curable inks. Check the specifications of the exact blade material grade before use.

Selection and Use Guidelines

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

▫ Use a correctly sized holder: Select a handle or blade holder suitable for a 9 mm thick blade. Clamp the blade evenly and securely.

▫ 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 and specialized cleaning agents.

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. Do not place heavy objects 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 reduce deformation and support consistent print quality. Allow the blade to rest after chemical exposure, and sharpen only when it is dry.
