Machin Definitives - When Production Goes Wrong
IntroductionChallenges in the production of postage stamps have always existed and whilst technology and quality control has improved to help prevent these, many of the same challenges faced in the 19th century are still current.
Advances in technology have led to the desire by the Royal Mail to improve efficiencies in mail sorting and to improve the security of stamps to reduce the potential for forgery. This has led to the use of phosphor overprinting, elliptical shaped perforation holes and a range of other features which their 19th century colleagues didn't need to worry about.
This exhibit is intended to provide an overview of some of the difficulties encountered by showing examples of where it went wrong, but still made it into circulation.
