Yes. And you should use it often because parameters change such as light source output, humidity and other factors.
If you're just practicing, you only need an area as big as the calculator so you can coat and expose multiple times on one screen.
Try different coatings also. One inside, one out. one inside, 2 out etc.
Finer mesh counts generally expose faster. Dyed fabric requires time adjustment.
Why would it sound like a dumb question if it's something you really don't know?
You asked and now you know
