This should be a vector format PDF, 8 mil trace, 6 mil space for the large groups of lines,
Have fun.
And for completeness sake, attached is an image of a zoomed in area of what a 600 dpi office laser printer can do with this file on plain paper. (HP laserjet 4000) I find it interesting that all the 45 degree corners appear to have almost a complete brake in the trace, and most of the smaller bends become curves.
