I
 

I/O

Input/output. Typically refers to sending information or data signals to and from devices.

IC

Integrated circuit.

ID

Identification.

IFO File

IFO file -- Navigation information file for a title set in the DVD-Video disc format. See also DVD Volume.

Image area:

Portion of paper on which ink can appear.

Impedance

The total of the resistive and reactive opposition, measured in ohms, that a circuit presents to the flow of alternating current at a given frequency.

Imposition

When a publication like a magazine is printed, the pages are printed on larger sheets of paper or reels. Multiple pages can be printed on the same sheet, for example 16 A4 pages will fit on a B1 sheet (8 on each side). After the printing the sheet is folded down to slightly larger than A4 so that when the edges are trimmed off the pages are held together by just the spine. In order to ensure the pages run in the correct order and are the correct way up after folding, they are printed in particular positions on the sheet. The placement of the pages on the sheet is called the imposition.

Imposition:

Positioning printed pages so they will fold in the proper order.

Impression:

Putting an image on paper.

Imprint:

Adding copy to a previously printed page.

Incoming Scene

 Indicia:

Postal information place on a printed product.

Injection molding

A manufacturing method where molten material is forced into a mold, usually under high pressure, and then cooled so the material takes on the shape of the mirror image of the mold.

Ink fountain:

The reservoir on a printing press that hold the ink.

Inkjet Printing

the method used for applying an image on the surface of a CDR; can be black or color.

Input selector

A routing switcher or auxiliary bus used to expand the number of video or key inputs that can feed an input of a digital picture manipulator or keyer. Many keyers only accept one key source and fill, but by connecting an input selector to those inputs, many more source and fill signals become available just by selecting crosspoints on the input selector.

Input-looping

A device's input loops back out so that the incoming signal can be sent elsewhere.

Insert

printed material placed in the front of a CD jewel case. AKA folders & booklets.

Integrated circuit

An electronic device in which both active and passive circuits are contained in a single miniature multi-pin package.

Intensity modulation (IM)

Used in fiber optics as a method of transmission in which the analog signal directly modulates the light source.

ISO-9660

ISO-9660 -- The file system used for CD-ROM. See also UDF (Universal Disc Format).
