Query: Hand-written notation hard to read

I'm not commenting on the content, but this is hand-written musical notation that looks like it has been through a few generations or recopying. It looks sloppy, and when you are taxing your brain trying to learn exercises, you shouldn't have to worry about reading muddy and blurry print the publisher was too lazy to spend a couple hundred bucks to transcribe into sharp, readable text. My "62nd printing" looks like it has been through a photocopier about that many times.
