In-Depth Information
yellow seen in Fig. 8-13 are in the range of 4 deltaE, and the colors in
green are low, around 1 deltaE. A few red colors are just above 8 deltaE.
By spinning this map in 3D, you can see how far off the measured data
is from the reference data and where in the profile this is taking place.
By clicking back to
True Color
radio button, the 3D map will show the
actual colors that the profile produces. When doing so, I see that the
higher deltaE values (seen in Fig. 8-13) shown in red are actually
the blue colors that the Epson profile has the largest issues reproducing.
ColorThink will also extract and save embedded ICC profiles from
images in a situation where you may need to load a profile on your
system that was originally embedded in an image. The Profile Medic is
very thorough, provides a list of possible errors broken down by their
problems, and presents this to the user, giving them the option to fix the
problem or move forward. The product doesn't appear to be as anal about
reporting errors after profiles are fixed like the ColorSync utility. Color-
Think is a powerful yet easy to use product and it is reasonably priced.
ColorThink can run under Mac OSX or OS9, or Windows XP/2000. For

Monaco GamutWorks
X-Rite/Monaco provides a very useful free utility to those owners of the
company's profiling products (MonacoPROFILER, PULSE ColorElite) that
provides some of the gamut viewing and profile analysis tools discussed
thus far. There are three separate work areas in GamutWorks:
Gamut
Viewer
,
Image Inspector
, and
Info Viewer
.
Gamut Viewer
The Gamut Viewer allows a user to open multiple ICC profiles and view
them in both 2D and 3D at the same time, as seen in Fig. 8-14. Multiple
profiles or images can be selected in the list window found in the upper
left of all three work areas. This provides information about the selected
items and the ability to show or hide the listed items. An elevator slider
allows you to slice through the gamut in both plots simultaneously. This
makes it easy to see how the entire distribution of colors throughout the
gamut ranges throughout the profile. Each profile can have different
color shading and there is control over opacity making it easy to see how
one profile's gamut may fit within the gamut of another profile. The 3D
gamut view can be enlarged and spun on its axis, making it easy to get
a bird's-eye view of the gamut even at very great enlargements. Gamut-
Works allows images to be loaded and their gamuts plotted as well, either
alone or over existing profiles. In Fig. 8-14, I have a custom Matchprint
profile loaded along with the Printer Test File image, which is represented
by the red dots in both the 3D and 2D views.
