As the product managers for HexWare and Hexachrome, Ken Wagner and myself,
Amy Fannon wanted to reply to the messages discussing the functionality of
HexImage. If you have any questions or concerns relating to HexWare or
Hexachrome in general please feel free to contact us directly at

"... After converting to a Hex profile in Photoshop you can *kind
of* get a preview of the Hex file as the multi-channel document has LAB
values specified as the Hex ink primaries for each color channel. But you
are not per say using an ICC Hex profile for previewing in Photoshop."
We do offer a preview solution within HexImage. Although HexImage will work
with RGB, CMYK or LAB images, we are going to assume RGB is the starting
point for this explanation.
When we first initiate our HexImage separation tool, what actually happens
is that the RGB image is converted to Hexachrome, using the selected
Hexachrome profile. It is then converted back to RGB for the purpose of the
preview (keep in mind that colors that were out of the Hexachrome gamut will
be reflected in the new RGB preview). The Hexachrome separated file that is
generated embeds the source (RGB) profile and the Hexachrome profile. This
has to be displayed in PS as RGB since PS has no support for Hexachrome and
would otherwise generate an inaccurate preview in multi-channel mode.
As Dan mentioned, there is also the ability to do global and local color
corrections on the Hex-separated file. The preview that is generated for
the HexImage color correction tool works in the same manner as the preview
for the separation tool, except that the profiles used are the ones embedded
in the Hex-separated document, not user-selected.
Another point we wanted to make is that there is another valuable tool
within HexImage, called RGB Proof, specifically designed for proofing. Once
an image has been separated and optionally color-corrected, this tool can be
invoked from the Automate menu. This will convert the Hexachrome file back
to a high-resolution RGB file using the embedded source and separation
profiles. This proof will accurately display in RGB the Hexachrome output
and can be saved and used for MANY purposes.

"And how about hard proofs? Any suggestions?"
There are several analog and digital systems that are PANTONE licensed
Hexachrome proofers:
As of April 26, 2002:
Dupont Digital WaterPoof/Chromalin AX4
Dupont WaterProof/Chromalin CV
Polaroid Polaproof Digital Halftone Proofing System
Fuji ColorArt
Kodak Approval XP4
Kodak Matchprint Negative Color Proofing Film with HiFi Proofing Set
(formerly a product of Imation)
Roland HiFi Jet Pro
Roland HiFi Jet
Another point to make is that HexWare ships with two products, HexImage
which is the plug-in for Photoshop but also HexVector which is a plug-in for
Illustrator 9/10 that allows you to work in Hexachrome, convert to
Hexachrome and print Hexachrome directly from within Illustrator.
Best Regards,
Amy & Ken
