Jeff, I'm not sure I would agree with that.
In my experience this appears to be an "overprint". The initial printing of the cards (with perfs) and certificates is done by a legitimate outside print shop and then they are brought in for finishing. A database is used to insert the PS'ers names. As evidence... run you finger tips lightly across the words "To view my other items" and then across your User ID name and you will feel the difference. They were done by different printing methods.
If in fact eBay did use an outside service it is a company that is doomed to failure. Third party print shops generally would by reliant on quality workmanship for survival in a very competitve industry.
