Embossing Or Not?! Bedazzled :)

Quote:

Engraved stamps show the ink lines slightly raised above the surface of the stamp and show corresponding depressions on the back. The degree of this depends on the relative depth of the engraved lines and on the ink and the paper used. Typography, the exact reverse of engraving, shows a slight raising of the lines on the back. More important for our purpose is the fact that the pressure of the typographic printing plate causes the ink to be squeezed toward the edges of the printed surfaces. This is visible as a fine frameline around the printed parts when one looks through the stamp under high magnification. The degree of this "framelining" depends on the pressure applied during printing and on the viscosity of the ink, and is a typical characteristic of each issue.
