Depends! Determining your exposure time comes down to two factors - the type of emulsion you’re using, and the mesh count of your screen. One way to find out is to use our free exposure calculator (get it here). Print it out on a transparency, and burn it on your screen. While burning, block all rows except one with an opaque paper. Follow the directions provided to calculate your correct time, but the idea is that as you move the paper down, each row will have a different burn time. Wash the screen out, and the row that washes out best will give you your burn time!
At home burning can be a little challenging at first, but the exposure calculator certainly makes things a lot easier.
