I've got a project coming up where the end-user would like to do two
kinds
of "proofing" on both a color laser device and an inkjet device. One
goal is
to do offset proofing. The other is to do what I would call
"presentation"
type of printer/proofing. For the presentation stuff I suggested an RGB
workflow but
There is no but. That recommendation is how it needs to be done if they
are serious about doing what they claim they want to do.
[but] it looks like that is not going to be possible as they want to
do sort of a "wide gamut" CMYK presentation printing.
No. The behavior of the laser printer and inkset are surely completely
different from each other, not just in terms of gamut but in terms of
the shape of the gamuts. They need to make conversions from an original
file, be it RGB or CMYK, for each output device, if they want the best
possible results on each output device.
IOW, re-purpose the
existing CMYK files and print them using an assumed/assigned wide
gamut CMYK
space.
This doesn't make sense. What are they repurposed for? Inkjet or laser?
Once repurposed, using some unapplicable "wide gamut" assumed/assigned
profile isn't going to do anything but screw up how they are treated in
applications, and if color management is used when printing, will screw
them up even more. It sounds like they are asking for magic. I suggest
you contact some Orthutangans who will be more than happy to help you
do what you want.
One suggestion by the customer was to take use the CMYK profile from
the inkjet device and use this as the source/assumed profile for the
color
laser/toner device.
That's insane. It's so crazy that if it actually works (chances=slim to
none), I don't want to know about it.
Rather than do that, I'd like to find a wide(er) gamut
CMYK space that I can use as a source/reference profile on both
devices.
It's called RGB. That's why it exists. They need to get over their RGB
phobia. And if they can't get over it, then they must accept a
compromise which will be more complicated, thus more prone to user
error, and it won't provide the best results on each device.
So, my question is, is there any known well-behaved wide CMYK spaces
out
there or do I need to manufacture my own? Something in the range of
AdobeRGB
or BruceRGB as a CMYK space would be ideal I think.
If the requirements are something like AdobeRGB or BruceRGB, just use
Adobe RGB or Bruce RGB. Problem solved.
