Whats up with the pixelization?

I tried re-importing the .jpgs, remaking the MC, and nudgeing it around and I’m still getting this pixelation. Notice it on the the type “SWISS NATIONAL BANK” on the “N”. I’m working on my graphic design portfolio and would hate for my all portfolio pieces to have some sort of small pixelation like this. Any suggestions/solutions?
