- Plotter
-
A device that draws lines on a piece of paper based on commands received from a computer.
It differs from a printer in that it uses a pencil to draw the lines so it can draw a continuous line where as a printer uses a series of dots.
Multi-color plotters have different color pencils.
Plotters are used when precision is necessary, such as in engineering applications.
Permanent Link

Pantone Matching System
A registered name for an ink color matching system used to compare, match and identify specific colors.
Permanent Link
- PMT
-
Photomechanical Transfer
A process where original copy is exposed to a photosensitive paper, which is then mated with a receiver paper.
The two are process together, which results in the image being transferred to the receiver paper, producing a black and white print.
No negative is needed in this process.

-
An identifying number that is unique to each purchase oder.
The PO number allow the correct purchase order to be referenced for tracking and billing transactions.

Print On Demand
Printing documents electronically when needed, rather than printing stock in advance and keeping it in storage.
Permanent Link
- Point
-
1.In regard to type, it is used to state the size of the type.
The ’’point size’’ of the type is measured from the bottom of the descender to the top of the ascender.
There are 12 points in a pica and 72 points in an inch.
2.When using in regard paper, it is the measurement of the thickness of the paper. 1 point equals 1/1000 of an inch.
The thickness of 10 pt. stock would equal 10/1000 or 0.010 in.
Permanent Link
- Point of Presence
-
A location where a network may be connected.
This can be done through dial up lines or lines can be leased to connect the network.
Permanent Link
- Point of Purchase
-
- Point of Purchase Display
-
A display that is located on the counter or in the area where a product is purchased.
Permanent Link
- Point-to-Point
-
A feature of a communications system that enables one or more stations to check with other systems to see if there is a message ready to be sent.
Permanent Link
- Point-to-Point Network
-
When only two stations can check to see if a message is ready to be sent.
They share the same transmission line at the same time.

- Point-to-Point Protocol
-
PPP
The most popular protocol for establishing dial-up connections to the Internet.
Permanent Link
- Point-to-Point Tunneling Protocol
-
PPTP
A new technology used to allow TCP/IP data to be transmitted over non-TCP/IP networks.
A common use for PPTP is to join physical networks together to form “virtual internets” using the Internet as a means to accomplish this.
The PPTP ensures that messages sent back and forth on the “virtual internet” are secure.

Permanent Link
- Polarization Filter
-
A transparent optical medium which only allows electromagnetic waves of one polarization to penetrate. Of the light waves normally moving in all directions, polarization filters only allow to pass those components of an oscillation that come from a certain direction.
These directed light beams hit the measured object and are then reflected partly in a mirror-like way. Unlike diffuse reflection, direct reflection does not alter the oscillation direction of light.
These components can be eliminated with a second polarization filter positioned at 90 degrees.
Densitometers with polarization filters show identical values for wet and dry prints which are, however, slightly higher than on devices without polfilters.

- Polarizing Screen
-
Filter
A filter that transmits light traveling in one plane while absorbing light traveling in other planes. When placed on a camera lens or on light sources, it can eliminate undesirable reflections from a subject such as water, glass, or other objects with shiny surfaces. This filter also darkens blue sky.

- Polaroid
-
A process in which finished photographs are produced within the camera device itself; the first major development in photography since the genre was invented.
The process works on the basis of developer substances in paste form, which are distributed over the imaged film after a photograph has been taken and act on the film by diffusion.
This method was invented by Edwin Herbert Land (1909-1991), who founded the Polaroid Corporation in 1937, and launched the first Polaroid Land camera in 1947.
This camera produced a black-and-white paper image one minute after the photograph had been taken.
The millionth instant camera was sold in 1956. The first Polaroid color camera was launched in 1963.
Polaroid declared bankruptcy at the end of 2001, as the technology has become obsolete, in large part due to the popularity of digital photography.

- Poly Bag
-
A clear bag, made of polyurethane instead of paper, used as an outside mailing envelope.
Generally used to mail magazines and newsletters.
Permanent Link
- Polyester
-
Polyester is a substrate that is durable and weather resistant, which is used as a base material for some types of film, printing plates and label facestock.
It can withstand high levels of abuse and abrasion, and resists most solvents and oils.
Polyester has high heat resistance and high tensile strength.
It is generally clear but is available with opaque and metallized finishes.
Permanent Link
- Polyester Plates
-
A plastic substrate used for analog and digital offset printing plates.
The polyester substrate is coated with an emulsion of either silver halide, which is imaged with lasers, or a toner-based coating, which is similar to the technology used for laser printers and copiers.
Polyester plates are suitable for smaller print jobs of less than 25,000 impressions.
Improved technology has resulted in plates that produce excellent results, allowing them to be used for almost any type of short run application.
