The purpose of grilling stamps was to break the fiber of the stamp paper so that when a cancel was applied the ink would soak into the paper and make washing the cancel off much more difficult. A grill is essentially an embossment of the stamp paper, in the form of a very small "waffle" pattern. (See left, illustration below.)

Grills on the earlier issues were very well defined. However, grilling stamps after they were printed introduced an extra step in the production process that added costs and delays, and, in order to reduce both, the practice of grilling up to six sheets at a time was adopted during the printing of the large "banknotes" of 1870-71. As a result, the grill impressions on these stamps are usually faint and incomplete. Such poor grills could scarcely be said to be doing their job, and soon afterward the experiment of adding grills to US stamps was ended.
