The paper used in most books SUCKS. Bleed through is going to be an issue unless your signing the inside flap of a hard cover volume. If you are going to use a fountain pen then a fine nib with a fast drying ink would be my suggestion. And for that the best possibility is to try lots of pen and ink combinations on as close to matching surface as possible.

But even though I prefer fountain pens over other choices, for your application it may not be the best selection.

AbE:

Warning. If you bought ink with the calligraphy set it probably should never be used in a fountain pen. Lots of calligraphy ink contains shellac to add in drying and permanency and if it fries in a fountain pen it pretty much ruins the pen.
