- Continer: gallon
- Handling: handle under yellow safelights (avoid exposure to sunlight, flourescent and incandescent lights)
- Mesh preparation: remove any contamination rsidual inks, cleaning chemicals, or dirt and dust. Murakami haza/ghost remover is a non caustic water soluble that will remove residual inks and emylsions. Murakami screen degreaser will help clean up other contaminants. Dry screen before coating.
- Coating procedure: On a clean dry screen apply one or two coats of emulsion to the print side. The rotate screen 180° and apply one or two coats of emulsion to the squeegee side. (additional coats may ne added to the print side if thicker stencils are required)
- Drying: Dry the print side dowm coated screen horazontally in a light safe area. 86-10 F° (30-40 C°) at 30 to 50% humidity with good air circulation. A screen drying cabinet with good heated airflow helps to maintain these conditions.
- Exposure: Clean the film positives and vacuum frame glass before exposure to minimize pinholes. Exposure is impacted by mesh colour, emulsion type, coating thickness, lamp type and the age of bulb. Exposure calculators help. Also remember that frosted film positives or with weak black density can reduce the resolution and definition qualities of the coated screen.
- Washout: Gently spray both sides of the screen with lukewarm water until the emulsion softens and then wash the print side of the screen until the image is fully open. Rinse both sides and dry.
- Reclaiming: Use Murakami screen cleaner to remove all excess ink from the frame. Remove the emulsion and rinse thoroughly. If required use a haze & ghost cleaner. Finally degrease, rerinse and let dry.
- Storage: A cool dry storage space is best to support the one year shelf life you can expect. Coated screens can be stored for up to a month when at 59-77 F° (15-25 C°) and 30-50% humidity.
