What's chalky paper? Gustamps explains.

When new stamp collectors come across chalky paper stamps, they often wonder why the stamps are printed that way. Gustamps explain that the chalky coating makes it virtually impossible to remove the postmark from a stamp, without disturbing the stamp's design. Gustamps point out the reason for this extra feature on some stamps is for security so that postal authorities can be sure the stamps can not be reused, saving costs on any lost postal revenue.
