Plate Number Coil
{{Unreferenced, date=May 2022 A plate number coil (PNC) is a United States postage stamp with the number of the printing plate or plates printed on it. The plate number typically appears as one or more small digits in the margin at the bottom of the stamp. The plate number may be centered or, on some coil issues, located toward the right. Although most plate numbers are composed of just numbers, both a combination of letter and number may be used. In the case when a letter is represented in the plate number, an upper case letter usually appears at the beginning or at the end of the sequence with the former serving as a good identifier of the stamp printer. The plate number is on one stamp out of the number of stamps printed by a single revolution of rotary printing press used to print the stamps. Collectors specializing in PNC collecting typically save plate number coils in the following formats: # PNC5 - Plate Number Coil 5 - A strip of 5 mint stamps with the plate number coil ...

Postage Stamp
A postage stamp is a small piece of paper issued by a post office, postal administration, or other authorized vendors to customers who pay postage (the cost involved in moving, insuring, or registering mail), who then affix the stamp to the face or address-side of any item of mail—an envelope or other postal cover (e.g., packet, box, mailing cylinder)—that they wish to send. The item is then processed by the postal system, where a postmark or cancellation mark—in modern usage indicating date and point of origin of mailing—is applied to the stamp and its left and right sides to prevent its reuse. The item is then delivered to its addressee. Always featuring the name of the issuing nation (with the exception of the United Kingdom), a denomination of its value, and often an illustration of persons, events, institutions, or natural realities that symbolize the nation's traditions and values, every stamp is printed on a piece of usually rectangular, but sometimes triangular ...

Printing Plate
Printing is a process for mass reproducing text and images using a master form or template. The earliest non-paper products involving printing include cylinder seals and objects such as the Cyrus Cylinder and the Cylinders of Nabonidus. The earliest known form of printing as applied to paper was woodblock printing, which appeared in China before 220 AD for cloth printing. However, it would not be applied to paper until the seventh century.Shelagh Vainker in Anne Farrer (ed), "Caves of the Thousand Buddhas", 1990, British Museum publications, Later developments in printing technology include the movable type invented by Bi Sheng around 1040 AD and the printing press invented by Johannes Gutenberg in the 15th century. The technology of printing played a key role in the development of the Renaissance and the Scientific Revolution and laid the material basis for the modern knowledge-based economy and the spread of learning to the masses.

Rotary Printing Press
A rotary printing press is a printing press in which the images to be printed are curved around a cylinder. Printing can be done on various substrates, including paper, cardboard, and plastic. Substrates can be sheet feed or unwound on a continuous roll through the press to be printed and further modified if required (e.g. die cut, overprint varnished, embossed). Printing presses that use continuous rolls are sometimes referred to as "web presses". Developmental history William Nicholson filed a 1790 patent for a rotary press. The rotary press itself is an evolution of the cylinder press, also patented by William Nicholson, invented by Beaucher of France in the 1780s and by Friedrich Koenig in the early 19th century. Rotary drum printing has been claimed to be invented by Richard March Hoe in 1843, and perhaps slightly earlier by Josiah Warren. A1844 patentreplaced the reciprocating platforms used in earlier designs with a fixed platform served by rotating drums, and through a ...

Postmark
A postmark is a postal marking made on an envelope, parcel, postcard or the like, indicating the place, date and time that the item was delivered into the care of a postal service, or sometimes indicating where and when received or in transit. Modern postmarks are often applied simultaneously with the cancellation or killer that marks postage stamps as having been used. Sometimes a postmark alone is used to cancel stamps, and the two terms are often used interchangeably. Postmarks may be applied by handstamp or machine, using methods such as rollers or inkjets, while digital postmarks are a recent innovation. History The first postmark, called the "Bishop mark", was introduced by English Postmaster General Henry Bishop in 1661 and showed only the day and month of mailing to prevent the delay of the mail by carriers. In England during the latter part of the 17th century, several postmarks were devised for use with the London Penny Post, a postal system that delivered mai ...

Philatelic Cover
A philatelic cover is an envelope prepared with a stamp(s) and address and sent through the mail delivery system for the purpose of creating a collectible item. Stamp collectors began to send mail to each other and to themselves early on, and philatelic mail is known from the late 19th century onward. While some collectors specialize in philatelic covers, especially first day covers and cacheted covers, others regard them as contrived objects that are not reflective of real-world usage, and often will pay a higher price for a cover that represents genuine commercial use. However, mail sent by stamp collectors is no less a genuine article of postage than is mail sent with no concern of seeing the mailed item again. Philatelic covers include mail from first airmail flight and first day of stamp issues ceremonies. Over the years there have been numerous Expositions where special postmarks are made and where a post office is set up where mail can be sent from on the given date of th ...
