Make sure your emulsion has the diazo sensitizer added. If you are mixing a new jar of emulsion, please date the cap to indicate emulsion has been added.

Fill your scoop coater with emulsion. It's better to use more than run out while coating a screen.

Do two passes on each side: one with the scoop coater nearly perpendicular to the screen to fully coat the screen, and one with the scoop coater nearly parallel to scrape off all the excess emulsion.

Leave the screen in the darkroom overnight to let the emulsion dry.

Position your positive centered and reversed on the top of your screen. Tape the corners.

Place the screen face down in the light box. Place the foam inside of the frame to prevent reflections from the lid exposing the emulsion behind your positive.

Close the lid and turn on the lightbox.

After exposure, remove the positive and rinse both sides of your screen. Let it sit for a few minutes.

With the nozzle close to the screen, wash out the emulsion. You can hold the screen up to the light to make sure you’ve washed everything out. Any remaining emulsion will cure under the shop lights once you the screen out of the darkroom, so be thorough.
