The #443 is 148 microns - it's medium-coarse. You'll end up with a lot of green.

The number 480 is 74 microns - better, but definitely not pure; this is about medium on a set of bubble bags.

Fine on a set of bags is around 25 microns.

Good choices for screen printing mesh are about a 74 mesh count (approx 220 micron - coarse for first screening); around 200 mesh count (approx 70 micron - medium for second screening); and around 350-400 mesh count (approx 25-40 micron - fine for last screening).
