I just know UBC has no raised seal on their official transcripts. The paper used is watermarked, has UV luminescent lint of various colours, the university logo, and come straight out of a printer, including the registrar's signature. Although they look plain blue, when you copy or scan them they show "VOID", just like a check. That, and the post mark on the outer envelope and special stickers they put on the seal of the inner, slightly smaller envelope, which are stamped with the date and a two-tone ink registrar's signature stamp. They can put, if absolutely necessary and requested, a round registrar' ink stamp on the original transcript. Most receiving institution consider these security measures to be sufficient. Sorry if this is not helpful.
