Just an update about what happened...
Contacted Apple Support and sended via Email examples of problem...
They said "ok, we print another copy and send it to you!" Nice and Good but the final result is the same!!!
So final conclusion is, "Do Not Print Books in Black and White!!!" if you pretend to have something quite similar to a real B&W Photo Book.
Probably this is due to the fact that all digital imaging, also B&W, are printed on color printers which do not use just Black for B&W prinouts but anyway all colors. So depending on printer settings results, at least for B&W are horrible.
