Post exposure image washes out of screen
Posted: Mon Oct 17, 2011 1:51 pm
Hello, This is my first screen printing expirience as well as my first forum.
My first attempt, all the holes were filled leaving no image . I used one coat of emulsion and exposed it for 10 minutes under a BBA NO.1 photoflood 250 watt bulb... 12" over screen. The emulsion was mixed 24 hours prior to this attempt.
My second attempt, the image came though clear after exposure but washed off when I rinsed it with a kitchen sink sprayer, luke warm . I put two coats of emulsion on my 10" by 14" screen, letting the first coat dry before applying the second then I let it sit over night. This was exposed for the same amount of time with the same bulb at the same height.
I used speedballs ultimate screen printing kit. The emulsion sat in a 75 deg. garage for 2 months prior to second attempt.
I am very excited to get this going. Any help is greatly appreciated.
Thank you,
dude
