Try a separation of about 1/8" (2-3mm) between screen and surface.
Make sure the ink is the right kind and mixed well and thinned to the
proper consistency. Use a sharp rubber or PU squeegee of the correct
length, at about a 45 degree angle to the screen. Make a single
stroke, then cover the printing surface lightly with ink using another
stroke (closer to 90' angle) with the screen lifted. Practice on
plenty of clean paper. You'll have to hold the paper down or it will
stick to the screen, and so might your panel.
