A book I received had two pages with what look like ink spots on them.  One page has a couple of drops and the other has a blotch about the size of a dime.  But it looks to me like it was a printing problem that resulted in the spots as opposed to a member getting ink on the pages.

Is the book still postable?  I don't mind it for myself but I was wondering if I will be able to repost the book when I am done. 

Yes, I think it is postable.

A printing error should always be OK unless it makes the book unreadable (missing or repeated chunks of pages, bad cuts that remove text, blotches of ink that render the text unreadable, etc).

What Sara said.  This subject comes up once in awhile and this seems to be how TPTB interpret the guidelines in this situation.

Yes, it is postable.  I have seen the same thing myself.  Like you though, I always worry a little bit that someone will think it's unpostable.  Have a great day!

Good to know.

Thanks everyone.

The book I am reading right now was purchased new, and has that a couple of places.  It's a printing error, and IMHO, completely postable.
