Using Murakami WSR Emulsion: Step-by-Step Guide:

Unlock exceptional screen printing results with Murakami WSR Emulsion. Follow these simple steps for precise application and impeccable prints:

Required Materials:

• Mesh degreaser
• Murakami WSR Emulsion
• Diazo which is included with the emulsion
• Emulsion scoop coater
• Clean drying cabinet
• Exposure unit with photopositive
• Lukewarm water source

How to Use Murakami WSR Emulsion:

Mesh Degreasing:

1. Apply mesh degreaser to both sides of the mesh, creating a lather.
2. Thoroughly rinse the screen and frame with water, allowing them to dry completely.

Coating Process:

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

Drying in Level Position:

1. Place the screen in a clean, dark drying cabinet.
2. Ensure the screens are level with the print side facing down.
3. Keep the cabinet temperature below 110 degrees Fahrenheit (43 degrees Celsius).
4. Allow the emulsion to dry thoroughly before proceeding.

Positioning Film Positive:

1. Place the film positive on the shirt side of the screen, ensuring it’s in contact with the emulsion.
2. Expose the screen with your exposure unit.
3. Exposure times may vary based on your light source and coating methods.
4. Accurate exposure is crucial 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.
6. Gently wash the print side until the image becomes fully visible. Thoroughly rinse both sides of the screen with water.
7. Ensure the screen is completely dry before moving to the printing stage.

Printing:

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

Final Tips:

Handle the screen and emulsion in a light-safe environment to prevent premature exposure. Store Murakami WSR Emulsion in a cool, dry area to maintain its quality. By following these steps, you can harness the potential of Murakami WSR Emulsion to achieve exceptional screen printing outcomes. Elevate your prints using this premium emulsion and realize your creative vision with precision and confidence.

For optimal emulsion results, use an exposure calculator customized to your setup. Exposure times may differ based on factors such as coating technique, light source, emulsion type, and thickness. An exposure calculator ensures accurate exposure times, allowing you to fine-tune your emulsion process for outstanding screen printing results.
