First you have to make sure that the screen is clean and degreased. Next, you take you screen into the darkroom where you will apply photo emultion with a scoop coater. You pour a bit of emultion into the scoop, then tilt the scoop so that the emultion is in contact with the screen. You pull the scoop upward leaving a thin layer of emultion on the screen. If there is excess it can be carded off with a credit card. Then you put away to dry.
After it has dried you put it on a raised piece of foam, and then you put your oiled black and white images face down on the screen, followed by a piece of glass to hold everything in place. The UV lights are turned on and left for 4 mins. Afterwards you quickly take the screen to a sink, rinse it to stop the chemical process, and use water pressure to remove the lighter portions of the emultion.
Lastly you take the screen, screw it down with printing hinges, and tape the edges were there is no emultion. You tape down a flop, flood the screen with the squeegee, and then print on the flop. You used the flop to gage where your paper should be. After that you flip the flop, place your paper, and print. Afterwards you scrap off the excess ink to save, and clean your squeegee, screen, flop, and area.
