Fig. 3 - HexImage Separation Profiles
3) Separation profiles contain the color
characteristics which affect the output of
the printer or printing press, including ink
set, dot gain, screening and paper stock.
Here you should choose the separation
profile that best describes the printing
process you will be using. You can also
create your own profiles for your specific
printing conditions.
Next, you can select Perceptual (for
images), Relative Colorimetric, Saturation
or Absolute Colorimetric as the Rendering
Intent. Perceptual is best suited for
photographic images, while Relative
Colorimetric is better to use when
separating artificially created images with
many bright and chromatic colors.
The preview window allows you to check
ink densities throughout the image (see
Fig. 2). After changing selections, clicking
the “Update Preview” button will update the
preview window with new ink densities.
Once you are satisfied with your selections,
simply click on the "Separate" button.
Fig. 4 - HexImage Global Color Correction
4) HexImage generates a new multichannel
document that contains the sixchannel
Hexachrome separations. (Keep
in mind that Adobe Photoshop does not
provide support for the Hexachrome color
space, so the preview may not be
accurate. However, the previews within the
HexImage windows are accurate.)
Now you can go to the Filter menu and
select HexImage Color Correction.
HexImage allows you to do either global
(see Fig. 4) or local (see Fig. 5). After
color corrections are made, you can apply
the color correction to the Hexachrome
image.
The separated document should be saved
as a DCS2.0 file for placement into Quark
or other applications.
