Unlock exceptional screen printing results with Murakami HV Emulsion. Follow these straightforward steps to achieve flawless prints and elevate your creative projects:

Required Materials:

Mesh degreaser Murakami HV Emulsion Scoop coater Clean drying cabinet Exposure unit with photopositive Lukewarm water source Clean and dim working space

Instructions:

1. Degrease the Mesh: Apply a mesh degreaser to both sides of the mesh, creating a lather. Thoroughly rinse the screen and frame with water, allowing it to air dry completely.
2. Coating Process: Place the screen on a stable surface, slightly tilted upward. Pour an adequate amount of Murakami HV Emulsion into the scoop coater. Hold the scoop coater at a slight angle and evenly apply the emulsion to the print side of the screen. Achieve 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, apply additional coats to the squeegee side while the emulsion is wet. Note: One coat on each side of Murakami HV is equivalent to four coats of wet-on-wet application with typical diazo-based emulsions. Allow each coat to thoroughly dry before applying the next.
3. Drying: Position the screen in a clean, dark drying cabinet with the print side facing up and at an upward angle. Ensure the drying cabinet’s temperature remains below 110 degrees Fahrenheit (43 degrees Celsius). Allow the emulsion to dry completely before proceeding.
4. Exposure: Place the photopositive in contact with the emulsion side of the screen. Expose the screen using your exposure unit. Exposure times may differ based on your setup. Achieve accurate exposure for optimal results. Utilize an exposure calculator to determine the ideal time.
5. Development: Gently spray both sides of the screen with lukewarm water. Wait around 30 seconds. Gently wash the print side of the screen until the image fully opens. Thoroughly rinse both sides with water. Allow the screen to fully dry before moving to the printing stage.
6. Printing: With the properly exposed and developed screen, you’re ready to begin the screen printing process.
7. Final Steps: Handle the screen and emulsion in a light-safe environment to avoid premature exposure. Store Murakami HV Emulsion in a cool, dry place to maintain its quality.

For optimal emulsion results, use an exposure calculator tailored to your specific setup. Exposure times can vary based on factors like your coating technique, light source, emulsion type, and thickness. Utilizing an exposure calculator ensures precise exposure times, allowing you to fine-tune your emulsion process for top-tier screen printing results.
