G'Day Rodney,
If typed the name as it is on the stamp E.E.U.U.DE VENEZUELA

it doesn't happen. However, for Colombia it will happen as there are some inscriptions that do not have dots.
I would not call the printed name on the face Moiré. Moiré is more of a geometric interference pattern. There is a set of Venezuela that has a geometric pattern printed on the face as a security measure. I would consider that pattern closer to Moiré.
