And invert refers to an error in printing in which one or more colors are 'inverted' in relationship to the others. The error can occur when a stamp is printed on more than one press and one or more sheets is sent through the second press oriented incorrectly. This was more common in the early years, today stamps are printed in a continuous run making it almost impossible to occur.
The most famous example would be the inverted Jenny airmail stamp. In the 1960's the US purposely created large numbers of inverts to reduce the value of a couple of accidental sheets with the Dag Hamerskold stamp. The most recent was a high value candle stamp in the 1990's.
