Editing Error (section)

{{main|Errors, freaks, and oddities}}
In [[philately]], an ''error'' refers to a [[postage stamp]] or piece of [[postal stationery]] that exhibits a printing or production mistake that differentiates it from a normal specimen or from the intended result. Examples are stamps printed in the wrong color or missing one or more colors, printed with a vignette [[Inverted Jenny|inverted]] in relation to its frame, produced without any perforations on one or more sides when the normal stamps are perforated, or printed on the wrong type of paper. Legitimate errors must always be produced and sold unintentionally. Such errors may or may not be scarce or rare. A ''[[Postage stamp design error|design error]]'' may refer to a mistake in the design of the stamp, such as a mislabeled subject, even if there are no printing or production mistakes.
