Oh the joys of color matching - and explaining why color matching is a little bit of science and art.
We almost exclusive use PMS Solid coated with screen colors. Our screen inks are pretty glossy regardless of the substrate.
Be careful buying used books. While it's probably ok, if a page was left open on someone's dashboard or in a window, they colors will fade making the book somewhat worthless. We date all our books when we open them for this reason.
