Would it really have mattered if I used the larger file she sent me, and left the artifacts in place? Probably not, but it would have irked me. I'm also irrationally prejudiced against unnecessarily large file sizes, even in this age of cheap broadband and storage: if I can fit 50 pages of sheet music into a 950 kB pdf, sticking a 3 MB image on the front page just feels *wrong*.

Then again: On paper it doesn't matter. Why not use the best possible quality there?
@solarkraft that's exactly what I ended up doing. A large file for printing, + a small file for the tablet users
