a process of printing which is the exact opposite of <#intaglio>, that is, the inked portion of the <#plate> is raised above the surface of the plate, as opposed to be being recessed below it. Letterpress (also see <#typography>) has been used to print <#overprint=overprints> on U.S. <#stamp=stamps>. It is also used in perfecting (back printing) inscriptions on the gum of many stamps, and to print most modern <#stampenv=stamped envelopes>.
