sky (Blue) and fruits (Red). Choose one pattern that looks best from the four image patterns
adjusted for typical lighting conditions. This method is ideal for beginners, since it requires no
special tools or color matching expertise.
2. For professional users
A method in which a professional colorimeter is used to obtain accurate readings of the
ambient light.
Take an accurate light measurement with Eye-One from X-Rite and the Ambient Light
Measurement Tool software from Canon, and then enter the measurement data in printer
driver or PosterArtist 2007. This method brings right adjustment, since it relies on actual
measured data.
[Kyuanos-related questions]
Q. How is it different from other color management modules (CMMs)?
Conventional CMMs are based on ICC profiles, but Kyuanos is a different type of CMM that uses
profiles of colorimetric data.
Q. How is Kyuanos color matching different from color matching based on regular ICC profiles?
Kyuanos has a function for performing color matching under different conditions of viewing. Again,
color-matching systems based on ICC profiles lack that function.
Q. How is Kyuanos color matching different from color matching based on regular ICC profiles?
There are two main differences.
First, Kyuanos has a function that models device characteristics (based on colorimetric data
obtained by measuring printed color test patterns, or "color patches"). Color matching-systems
based on ICC profiles lack this function. Thus, the format of Kyuanos profiles is unlike that of ICC
profiles. Kyuanos profiles include colorimetric data obtained by measuring color patches. ICC
profiles, on the other hand, include color processing conversion tables generated from
colorimetric data obtained by measuring color patches.
Second, Kyuanos has a function for performing color matching under different viewing conditions.
Again, color-matching systems based on ICC profiles lack this function. Thus, Kyuanos profiles
include both colorimetric data obtained by measuring color patches and viewing condition
parameters.
In addition, color processing conversion tables in ICC profiles can be applied for Kyuanos.
