Interesting, do you have any pictures? Do you know if the print you bought is the same as the official Japanese print? I recall the same issue with the (first) English version of BLAME.
Sorry for the half assed image, spoiler for volume 1 chapter 5 :
The photo is a bit brighter than reality and I'm under natural light so it's kinda readable, but if you're reading at night with a weak light you have to really concentrate to see something. Even if I've read the scans, the
fight with the executor (they translated their name in the first volume has 'condamned' btw) was mostly unreadable. But the other 'normal' scenes seem to be ok, I think they wanted to do something like 'muh somber darkness'.
