After one week after having received my printed book I have noticed, at my deepest dismal, that the initial acceptable B&W neutral tone has started shifting to a very bad greenish cast. Now, after one month almost, I have a good book, decently printed on a beautiful paper with a terrible green cast, unpresentable to anybody who understands what's B&W. Could you just tell me what's wrong in the printing process? No tested paper or/and inks? Obviously, that shouldn't happen. I'm deeply disappointed and looking for some explanation about this. Best wishes
