FMXPress was used on this to match the original art. Yes it looks grainy but that was the style used in the art, It worked well.
We tried to bump the screen freq up using ellipse, and double dot but it looked awful. Anything under the print pass size works well with fmx. We do use this dither alot on the small stuff.......
