Chromaline ChromaBlue Photopolymer Emulsion – Ideal for Plastisol Ink Printing

Using Chromaline ChromaBlue Emulsion: Step-by-Step Guide

Note: Always work in a light-safe environment to prevent premature exposure.

Achieve outstanding screen printing results with Chromaline ChromaBlue Emulsion by following these step-by-step instructions for proper application and exposure.

Materials Needed:

• Mesh degreaser
• Chromaline ChromaBlue Emulsion
• Scoop coater
• Clean drying cabinet
• Exposure unit with photopositive film
• Lukewarm water source
• Dark, dust-free workspace

Instructions:

1. Degrease the Mesh

Apply mesh degreaser to both sides of the screen, creating a lather. Rinse thoroughly with water and allow the screen to dry completely before coating.

2. Coat the Screen with Emulsion

• Place the screen on a stable surface with a slight tilt.
• Pour ChromaBlue Emulsion into a scoop coater.
• Hold the coater at a slight angle and apply a smooth, even coat to the print side of the screen.
• Flip the screen and apply one coat to the squeegee side.
• For a thicker stencil, apply additional coats to the squeegee side while the emulsion is still wet.
• Note: One coat of ChromaBlue is equivalent to four coats of wet-on-wet diazo-based emulsions.

3. Dry the Screen

• Place the screen in a clean, dark drying cabinet with the print side facing down.
• Keep the drying temperature below 110°F (43°C).
• Allow the emulsion to dry completely before exposure.

4. Expose the Screen

• Position the film positive on the shirt side of the screen, ensuring full contact with the emulsion.
• Use an exposure unit to expose the screen.
• Exposure times vary depending on light source and coating thickness—use an exposure calculator for precise results.

5. Develop the Stencil

• Spray both sides of the screen with lukewarm water.
• Wait 30 seconds, then gently wash the print side until the image fully appears.
• Rinse both sides thoroughly and allow the screen to dry completely before printing.

6. Proceed to Printing

Once fully dry, the screen is ready for screen printing with plastisol inks.

7. Storage & Handling

• Keep the screen in a light-safe environment until use.
• Store ChromaBlue Emulsion in a cool, dry place to maintain quality.

Optimize Your Exposure Process

For best results, use an exposure calculator tailored to your setup. Exposure times depend on:

• Coating technique
• Light source
• Emulsion thickness
• Stencil detail requirements

Using an exposure calculator ensures consistent, high-quality results and helps fine-tune your emulsion process.
