AM Halftone dot integrity for conversions to 1-bit monchrome

A quick test I made... interesting how 3 programs convert to 1-bit. I love Photo-PAINT, but hopefully the next version will have better integrity relative to the others shown.

I intentionally used a low line screen to reveal the circle integrity.

Can you point me to any documentation on how to set the line screen in ghostscript?
Cannot be done in ghostview, right?

Seeing the difference pointed out here makes me feel like I should confirm my assumption... I've always assumed that converting to monochrome in DRAW uses the PAINT functions, so there is no difference, right?

Have you any idea how Andromeda's Screen Filters would stack up against these?
