The philatelic use of the word Gutter is the space in form of paper left between two or more postage stamps that allows them to be separated or perforated.
Stamps with Gutter
When stamps are printed on large sheets of paper that will be guillotined into smaller sheets along the gutter it will not exist on the finished sheet of stamps. Some sheets are specifically designed where two panes of stamps are separated by a gutter still in the finished sheet and gutters may, or may not, have some printing in the gutter. Since perforation of a particular width of stamps is normal, the gutter between the stamps may or may not be of the same size as the postage stamp.
Several derivative terms exist:
Gutter pairs are two stamps separated by a gutter.
Gutter block is a block of at least four stamps where either the vertical or horizontal pairs, or both, are separated by a gutter.
Gutter margin is a margin dividing a sheet of stamps into separate panes.
