This term can refer to either the printed denomination of a stamp or to its monetary market value to a collector or dealer. The term also refers to the relative light or dark of a color, on a scale from white to black; thus, a high-value color is a very light pastel shade. A low-value color is very dark.
A relatively modern type of stamp that uses a form of key plate to produce the basic (but blank) background design. Computer printers then print the denomination on the stamp at the time it is vended. U.S. variable- denomination and Autopost stamps are included in this category, as are the various Frama and other types of foreign computer-vended stamps.

Vertical Pair, Imperforate Horizontally
Vertical pair of stamps lacking horizontal perforations between stamps and with horizontal straight edges at top and bottom. Perforations are present at left and right sides.
A term that relates more to centering than to overall condition. A stamp that has very fine centering is slightly off center, but has clear more-or-less evenly spaced margins surrounding the design. Imperforate examples have four decent margins.
The central design portion of a stamp. In most cases, this is a portrait, but it can include other strong design elements contained within the border as well. A second and much less commonly used meaning of the word comes from an early French term that described pictorial labels with no postal value.
