33 50Hz strobe disc pdf very poor quality

Well, printed off the 33 50Hz pdf and the lines are all over the place.
Checked the other pdf`s and they all have nice crisp lines>
Is it possible to update the 33 50Hz pdf to a nice clear image Please
(not my printer at fault)

33.33rpm 50Hz

I've uploaded an improved version of this disc
