Reply To: Should gold overprint or knock out?

Gold ink is not exactly the same as other 'regular' inks, as it is much less oilier. I think I've heard it's best when printed directly onto the paper (a knock out), and it may cause smudges when printed on top of other inks.

By the way, as almost all inks, it's not really opaque, so the apparent color will change when printed over another color.

To be totally sure, you should ask your printer. He will know how his brand of gold ink behaves on his own press.
