I can't see why you can't somewhat reproduce it (only if you want to compare your copy).
1) You have a pdf file and view at 500%
2) Since I didn't crop the image, you can compare your shot with mine at 1:1
Now speaking of screen resolution, it wasn't matter imo because when viewing the chart at 500%, even a super old 840x1024 turns into a 4200x512000 which is plenty of resolution.
Now if yours at 1:1 is smaller/bigger than mine meaning you were further/closer to the screen respectively.
I just hope it helps a potential buyer who may looking.
I checked the image at 300% and didn't feel a tripod would improve much.
