Packet Internet Groper

Ping is the name of a computer network tool used on TCP/IP networks (such as the Internet). It provides a basic test of whether a particular host is operating properly and is reachable on the network from the testing host. It also provides estimates of the round-trip time and packet loss rate between the hosts. It works by sending ICMP packets to the target host and listening for replies; its operation is analogous to active sonar in submarines, in which an operator issues a pulse of energy (a network packet) at the target, which then bounces from the target and is then received by the operator, hence the name.
Abbreviation: PING

Page

Page Description Language

The format used to describe the position of elements within a page elements as well as the page's relative position within a document. The output device then translates the format into a reproduction of the original image.
Abbreviation: PDL
Alternative Term: Page Descriptor

Page Makeup

1. Using a computer application to create a single or multi-page document, including the positioning of type, line art, photographs, etc. The document is then output to an imaging device. 2.

Pica

A pica (pronounced "PIKE-ah") is a unit of measure traditionally used in document layout. A pica measures 1 / 6 of an inch, and is used to measure the size of blocks of type, margins and other macroscopic elements of page layout.
1 / 12 of a pica is a point, which is the standard unit for measuring font size and leading. There are 72 points in an inch or 6 picas in an inch.
A measurement in picas is usually represented by placing a small letter p after the number of picas. "10 picas" is thus abbreviated to "10p". Likewise, points are represented by placing the number of points after a small p, such as 0p5 for "5 points", 6p2 for "6 picas and 2 points" or 1p1 for "13 points" which is converted to a mixed fraction of "1 pica and 1 point".
Abbreviation: p

Picking

1. When the tack of ink is stronger than the surface strength of the paper, some lifting of the paper surface occurs; this is referred to as picking. 2. An occurrence in printing whereby the tack of ink pulls fibers or coating off the paper surface, leaving spots on the printed surface.

Pico

Pico is an SI prefix in the SI system of units denoting 10-12 or one trillionth.
Confirmed in 1960, it comes from the Italian piccolo, meaning small.
Abbreviation: p

Picture Element

A picture element is one of the many tiny dots that make up the representation of a picture in a computer's memory. Usually the dots are so small and so numerous that, when printed on paper or displayed on a computer monitor, they appear to merge into a smooth image. The color and intensity of each dot is variable.
Abbreviation: Pixel

Piling

Pin Register

Pinholing

Pixels Per Inch

Pixels per inch or pixel density is a measurement of the resolution of a computer display, related to the size of the display in inches and the total number of pixels in the horizontal and vertical directions. This measurement is often referred to as dots per inch, though that measurement more accurately refers to the resolution of a computer printer. PPI may also be used to describe the resolution of an image scanner or digital camera.
Abbreviation: PPI
See Also: Dots Per Inch

Plastic Comb

Platemaking

Creating a printing plate that is completely prepared for use on the press. The process starts with a blank plate, which is then exposed to the image film, developed, and sensitized (if needed).

Point

A point is a unit of measure in typography. There are various sorts of points, used in particular locations and times:
   - PostScript Point or Computer Point: defined as 1/72 of an English inch or 0.35277 mm by Warnock and Geschke, the inventors of Adobe PostScript. Now the universal point in computers
   - American Printer's Point: defined as 0.013837 in or 0.35145 mm by Nelson Hawks in 1879
   - Fournier Point: the first definition of the printer's point, by Pierre Fournier. It was 0.34882 millimeters, which was 1/12 of a cicero
   - Didot Point: the French typesetting point defined by Ambroise Didot in the 18th century. It equals 0.37597 mm, which are 1/72 of a French royal inch (pouce)
   - Berthold Point: an attempt to create a point with a metric definition. 0.37593 mm or 1/2660 of a meter
   - German Didot Point: defined in 1954 as 0.376065 mm. This is the standard Didot point now used in Europe (unless replaced by metric typographic units)
On computer displays there are two accepted resolutions for typesetting, 72 and 144. Thus, one pixel represents one or two points respectively. The default setting for Macintosh Computers is 72pt per inch, the default for Windows is 96pt per inch.
The point is the standard unit for measuring font size and leading and other minute items on a printed page.
Twelve points make up a pica, there are 72 points in an inch, or 6 picas in an inch, a point is 1/12 of a pica. A measurement in picas is usually represented by placing a small p after the number of picas. "10 picas" is thus abbreviated 10p. Likewise, points are represented by placing the number of points after a small p, such as 0p5 for "5 points", 6p2 for "6 picas and 2 points", or 1p1 for "13 points" which is converted to a mixed fraction of "1 pica and 1 point".
Abbreviation: pt
See Also: Point Size

Point Size

The height of a typeface. A point equals 0.0138 inches.
Alternative Term: Type Size
See Also: Point, Unit Set

Portable Network Graphics

A .png is a lossless bitmap image format. PNG was created to both improve upon and replace the .gif format with an image file format that does not require a patent license to use. PNG is officially pronounced as "ping", but it is often just spelled out; possibly to avoid confusion with the internet tool ping.

Abbreviation: PNG
File Extensions: .png
