I recently ordered $100 worth of author copies in order to sell at conventions, etc, and discovered that ALL of them have an identical printing error that was not present in the proof copies that I approved. The front cover bleeds into the spine by as much as 2-3 millimeters and is clearly visible on EVERY book.
For the record, I used KDP Paperback's cover creator to make these covers and did not screw with the placement of the front cover image after I uploaded it. It's obvious to me now that the cover creator is flawed, and I will not be using it in the future.
If I cannot resolve this issue with KDP customer support, or if the new covers I upload have the same problems, I will be forced to pull all my books from KDP Paperback and go with someone else.
Needless to say, I am pissed.
