| Illuminant |
Mathematical
description of the relative spectral power distribution of a real
or imaginary light source, that is, the relative energy emitted
by a source at each wavelength in its emission spectrum. |
| Illuminant
A (CIE) |
Incandescent
illumination, yellow orange in colour, with a correlated colour
temperature of 2856K. It is defined by its energy output in the
wavelength range of 380-770nm. |
| Illuminants
D(CIE) |
Daylight
illuminants, equal in colour quality to noon daylight, or equal
to a black body heated to 6,500K |
| Imagesetter |
An output device to image bitmap data onto litho film or paper.
Comes in drum and flatbed models. |
| Indexed
Colour |
A
colour system that defines a palate of colours to be used in a specific
image. Often this makes images small and manageable. |
| Infra-Red
Dryer |
A
method of stoving ink films employing radiant energy from sources
such as gas-heated panels, filament lamps or low temperature electrical
radiants. |
| Ink |
A
material which is capable of being applied to a substrate to leave
a permanent mark. |
| Ink
Adhesion |
The
bond between ink and film. |
| Ink
Trough |
This
is where the ink is held in pad printing. Also called ink well,
ink reservoir, ink bath. |
| Inkjet
Printer |
A
type of printer that sprays tiny streams of quick-drying ink onto
the paper. |
| Inkjet,
phase change |
This
type of inkjet technology uses solid wax inserts instead of traditional
inks. The wax is heated to liquidity and deposited onto the substrate
through the print head, where it hardens on contact. |
| Intensity |
The
amount of light reflected or transmitted by an object with black
as the lowest intensity and white as the highest intensity. |
| ISDN |
Abbreviation
for Integrated Services Digital Network technology that supports
both voice and data services over copper telephone lines. |
| ISO |
Abbreviation
for the International Standards Organisation that designates international
standards. |
