Frequently Used Terms
The following section provides a brief list of terms that are used frequently within this User Guide, as well as
the CalMAN RGB software.
Workflow:
SpectraCal uses the term “workflow” to refer to the set of software pages that together
contain the instructions and action buttons for a specific calibration process. CalMAN
RGB, for instance, includes the Standard Monitor Calibration workflow and the
Advanced Monitor Calibration workflow – both of which provide instructions and action
buttons for their respective calibration processes.
Host Computer:
The host computer is the computer on which CalMAN RGB is installed. A host computer
can be used to calibrate any connected monitors, or to calibrate a remote computer on
a shared local network.
Target Monitor:
The target monitor is the monitor you intend to calibrate with CalMAN RGB software.
“Target monitor” may refer to a monitor connected to the host computer directly, or it
may refer to a monitor that is connected to the host computer through a shared local
network.
CalMAN Client 3:
CalMAN Client 3 is the internal pattern source software used by CalMAN RGB during
calibrations. The Client 3 also stores calibration data from CalMAN RGB, which is then
accessed every time your computer is opened to ensure you monitor adheres to the
calibration adjustments made by the software. CalMAN Client 3 is housed in your
computer independently of the calibration software itself.
Light Meter:
A light meter is the device used to measure the chromaticity (the color of output light)
and luminance (the brightness of output light) of your computer monitor.
Pattern Window:
A pattern window displays reference patterns on your computer monitor, which are
then measured by the light meter and read by CalMAN RGB software. There are two
pattern windows used by CalMAN RGB – one within the CalMAN RGB application and
one uploaded from CalMAN Client 3.
DDC (Direct
DDC is a software feature included in the Advanced Monitor Calibration workflow that
Display Control):
allows you to control your monitor’s display settings through the CalMAN RGB software
itself.
LUT (Look Up Table)
: A LUT (lookup table) is a set of data-points stored in your computer during Advanced
Monitor Calibrations that provide correction values for the errors exhibited by your
monitor. The data in an LUT is used by your computer to compensate for the
inaccuracies detected in your monitor’s output signal.
ICC Profile:
Like a LUT, an ICC Profile is created and stored in your computer during the calibration
process. An ICC Profile informs computer applications of your monitor’s color errors.
The applications then use the ICC Profile to provide an output signal that compensates
for the monitor’s color inaccuracies.
