INSTRUCTIONS FOR HANDLING & USE
Murakami Aquasol SP-1400 (similar to most emulsions) should only be applied and handled under yellow safe lights, to deter from exposure to UV lights, fluorescent and incandescent lights as well.
Murakami Aquasol SP-1400 is not pre-sensitized. Upon purchase, you will need to mix the sensitizer according to the instructions on the container. Gradually pour the solution into the emulsion while mixing thoroughly. To reduce air bubbles, let your emulsion stand for two hours before using.
Thoroughly clean your mesh with a degreaser before application. Remove any contamination, residual ink, leftover cleaning products, or dirt and dust is important. Garston sells a variety of degreasers and haze or ghost removers to help prepare your screens before application:
Weh applying your emulsion, you will need a clean, dry coating trough or scoop coater for the process. To avoid uneven application, make sure the surface of your tool is nick free. Apply one or two coats of the Murakami Aquasol SP-1400 to the print side of your mesh. Then, rotate the frame 180 degrees and apply either one or two coats of your emulsion to the squeegee side. Coating both sides of the screen will eventually help securely bind your image to the fabric during production. For thicker stencils, If you need to use a thicker stencil, use additional coats of your Murakami Aquasol SP-1400 as needed.
Place your screen horizontally with the print side down. Make sure you are in a clean light safe area. Alternatively, you can also use a screen drying cabinet to help with heated airflow and to maintain these aforementioned conditions. To completely dry your coated screen, you will need to have:
Exposure to your screen will be caused by mesh color, emulsion type, thickness coating, type of lamp you are using and age of the bulb itself. Exposure times depend on the mesh count. Exposure counts listed below are used in reference to a 5KW Metal Halide lamp with a distance of 40°.
Mesh Count 86-White: 150-175 seconds
Mesh Count 110-White: 120-150 seconds
Mesh Count 200-Yellow: 90-120 seconds
Mesh Count 300-Yellow: 60-75 seconds
Mesh Count 350-Yellow: 30-50 seconds
Gently spray both sides of the screen with lukewarm water to rinse out the Murakami Aquasol SP-1400, wait a few seconds to allow emulsion to soften then wash print side of screen until image is fully open.

INSTRUCTIONS FOR STORAGE:
Your Murakami Aquasol SP-1400 Emulsion should be kept in a cool dry area. Unsensitized emulsions will have a shelf life of at least one year if properly stored at room temperature. For best results, we recommend using the sensitized emulsion within 2-3 weeks. If you choose to leave your screens coated, they can be stored up to one month, but only if they are stored in these conditions:
Extending the Life of Your Emulsion
Always gently mix your Murakami Aquasol SP-1400 emulsion before use and every time you use it.
Keep your emulsion in a cool area, being in the heat will break down the components of your emulsion quicker. You can keep emulsion in the fridge (read the instructions on your product before doing so), but freezing your emulsion will render it useless.
Keep the lid to your emulsion tight, avoiding air and light leaks
To keep track of when you last used your emulsion, add a date to the container when you are storing it. Temperature and humidity are two large factors in the expiration of emulsion.
