Micrograph

From Tardis Wiki, the free Doctor Who reference

A micrograph was a form of identification. Shirna and Vorg owned a document which was micrographed by the Great Zarb, a Wallarian wrestler they had previously met at the instellar exhibition.

After his application to receive an entrance visa to the planet Inter Minor was rejected, Vorg presented Pletrac with this micrographed document, attempting to pass it off as being micrographed by the president Zarb, though Pletrac would later discover this to be untrue. (TV: Carnival of Monsters)
