Target Colorspace
The process that brings a device into compliance with a target specification or
standard. In the case of the Artisan™ Color Reference System, this involves
measuring the display’s screen output, comparing that output with a set of values
specified by the user, and adjusting the display’s color temperature, gamma, and
black and white luminance to comply with the specified set of values.
Each time you calibrate your Artisan™ Color Reference System the software
creates a Calibration Data File. This file contains items such as Target Colorspace,
Date, Bit Depth, Display Resolution, Refresh Rate, and Calibration Data. The
Artisan™ Software allows you to load previously created Calibration Data Files by
selecting them from the Calibration Data list.
A software routine that modifies numerical values sent to or from hardware devices
in order to make those devices' color output consistent.
A representation of the variety and range of colors that can be produced by a
specific color output device (such as a display).
Measured in Kelvins, color temperature is the color of light that an ideal black-body
radiator emits when heated to that temperature. So, if an ideal black body is heated
to 5000 K, then it will glow a reddish-white (this is the lower range of a display’s
color temperature). If that body is heated to 9300 K, then it will emit a bluish-white
(the upper range of a display’s color temperature). Setting a display’s color
temperature will define the display’s ability to display other colors.
A device located in a computer’s graphics card that translates digital output from
the computer into an analog form useable by the computer’s display.
A committee made up of hardware and software vendors. The purpose of the ICC
is to create cross-platform standards for color consistency and communication.
A data file used by color management systems to define color and match it across
hardware and software components. It works by defining the color of an abstract
color space (such as Sony RGB) described within a software program in the terms
of a device-independent color model.
The Target Colorspace specifies the colorspace that will be used each time a new
calibration is created. The colorspace information includes White Point
(Chromaticity and Luminance), the Black Luminance, and the desired Luminance
Response Curve (i.e. Gamma 1.8).
