A ketubah is a piece of art... like my husband and my ketubah it may be completely original, or it may be a print which the couple will personalize. All are art. All are beautiful.
I found a cute blog post from a bride who forgot that her Ketubah required a white pen in order for the signatures to be seen.
We were able to use regular pen... but I can guarantee that my husband spent a lot of time practicing his Hebrew script to ensure that it was written correctly. (And what is sweet is two of our witnesses ended up getting married about 2 years after our wedding).
