Murakami Photocure SR Screen Printing Emulsion – High-Resolution Photopolymer Emulsion for Solvent, UV & Plastisol Inks

Using Murakami Photocure SR Emulsion: Step-by-Step Guide

Unlock the potential of exceptional screen printing with Murakami Photocure SR Emulsion. Follow these simple steps for precise application and impeccable prints:

Materials Required:

• Mesh degreaser
• Murakami Photocure SR Emulsion
• Emulsion scoop coater
• Clean drying cabinet
• Exposure unit with photopositive
• Lukewarm water source

Step-by-Step Guide:

1. Mesh Preparation: Degrease the Mesh

• Apply mesh degreaser to both sides of the mesh, creating a lather.
• Thoroughly rinse the screen and frame with water, then allow it to dry completely.

2. Coating Process: Apply Photocure SR Emulsion

• Position the screen on a stable surface, slightly tilted upwards.
• Pour a sufficient amount of Murakami Photocure SR Emulsion into the scoop coater.
• Hold the scoop coater at a slight angle and apply the emulsion to the print side of the screen.
• Ensure even and consistent coverage with a smooth, steady pass.
• Flip the screen and use the scoop coater to apply one coat of emulsion to the squeegee side.
• For a thicker stencil, add more coats to the squeegee side while the emulsion is wet.
• Note: Applying one coat on each side of Photocure SR is equivalent to four coats of wet-on-wet application with standard diazo-based emulsions. Allow the emulsion to fully dry between coats.

3. Level Drying:

• Place the screen in a clean and dark drying cabinet.
• Ensure the screens are completely level with the print side facing down.
• Maintain the cabinet’s temperature below 110 degrees Fahrenheit (43 degrees Celsius).
• Allow the emulsion to thoroughly dry before proceeding.

4. Film Positive Placement and Exposure:

• Position the film positive on the shirt side of the screen, ensuring contact with the emulsion.
• Expose the screen with your exposure unit.
• Exposure times may vary based on your light source and coating methods.
• Accurate exposure is essential for optimal results. Use an exposure calculator to determine the ideal exposure time.

5. Development:

• Gently spray both sides of the screen with lukewarm water. Wait about 30 seconds.
• Gently wash the print side until the image is fully visible.
• Thoroughly rinse both sides of the screen with water.
• Ensure the screen is entirely dry before moving to the printing stage.

6. Printing:

• With the properly exposed and developed screen, you’re ready for the screen printing process.

7. Final Steps:

• Handle the screen and emulsion in a light-safe environment to avoid premature exposure.
• Store Murakami Photocure SR Emulsion in a cool, dry area to maintain its quality.
