[Color Concepts and Terminology]
Q. What does color temperature refer to?
When objects are heated, they emit light. This is called black-body radiation. Since the spectral
distribution of black-body radiation is determined by its absolute temperature, the
correspondence of color to temperature is established and colors can be represented as
temperatures. Reddish colors indicate a low color temperature, and as the color temperature
increases, the color changes from orange to white to bluish white.
Q. What are profiles?
In the context of color management, profiles are generally definitions of color characteristics for
individual devices. ICC profiles are currently a popular kind of profile. In contrast, Kyuanos
profiles include colorimetric data and conditions of observation that are not included in ICC
profiles. Color matching for a monitor and printer, for example, involves monitor and printer
profiles.
Q. How is color matching generally performed at present?
Color matching based on ICC profiles is most common in fields of graphic arts and printing. ICC is
an abbreviation for
International Color Consortium, an organization that defines ICC profiles.
Q. What are ICC profiles?
ICC is an abbreviation for
International Color Consortium. ICC profiles are one type of profile
defined by the ICC, and they have become a de facto standard in fields of graphic arts and
printing.
Q. What are viewing condition parameters?
Viewing condition parameters are parameters for color matching performed under different
observation conditions.
For example, in the case of color matching for a monitor and a printer, the input viewing condition
parameters are the white point information of the monitor and the monitor brightness. The output
viewing condition parameters are the white point information of the lighting of observation and
the brightness of the lighting where viewed.
Q. What is proofing?
Proofing is the step of checking how colors will ultimately be printed. In proofing, the colors as
ultimately produced in offset printing are simulated for checking.
