Using Murakami SP-1400 Emulsion: Step-by-Step Guide:

Attain exceptional screen printing results with Murakami SP-1400 Emulsion. Follow these simple steps for precise application and impeccable prints:

Materials Needed:

• Mesh degreaser
• Murakami SP-1400 Emulsion
• Diazo which comes with the emulsion
• Emulsion scoop coater
• Clean drying cabinet
• Exposure unit with photopositive
• Lukewarm water source

How to Use Murakami SP-1400 Emulsion:

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. Coating Process: Position the screen on a stable surface, slightly tilted upwards. Pour an ample amount of Murakami SP-1400 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 SP-1400 is equivalent to four coats of wet-on-wet application with standard diazo-based emulsions. Allow the emulsion to fully dry between coats. Level Drying: Place the screen in a clean and dark drying cabinet. Ensure the screens are completely level with the print side facing down. Keep the cabinet’s temperature below 110 degrees Fahrenheit (43 degrees Celsius). Allow the emulsion to dry thoroughly before proceeding. Film Positive Placement: 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 vital for optimal results. Use an exposure calculator to determine the ideal exposure time. 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. Printing: With the appropriately exposed and developed screen, you’re ready for the screen printing process. Final Steps:

Handle the screen and emulsion in a light-safe space to avoid premature exposure. Store Murakami SP-1400 Emulsion in a cool, dry area to preserve its quality.
