Print quality varies from batch to batch.

I received my second batch of books and these look much better than the first box that I ordered. (I didn’t complain of a problem with the first order.)
On the one hand, I’m very pleased, but I’m also very annoyed that the first 30 books are being circulated with less than optimal quality!!!
I understand that Blurb uses different printing companies but this is now a problem to me as I wonder what quality the third reorder will be………..
OH for consistency!!!!!!
