Good morning,
Thanks for your message. Yes, the price includes the signing, grading and encapsulation of your book. If you wanted to include pressing services that would be an additional $20.
While you can't request a specific color of ink, all the artists will sign using what they feel is best for the book. Obviously, if your book has a dark background and black ink is not going to show up then the artist will use a different color so the signature is visible. You just can't choose the specific color, unfortunately.
If you have any other questions, please let us know. Thanks!
