Don't Expect Exact Color Rendering in Future Copies of Same Book
As per Blurb's recommendation, I made one copy of a photo book to evaluate the color rendering. As I was quite pleased, I ordered 5 more copies. The color rendering was not as good as the original book. The warm tones were just a fraction off from the original. So, in the end, I would have been better off ignoring their recommendation and ordering the six total books as one order from the start.
