Is there any program to convert CMYK images to CMY images ?
Jean-Marie PIERRARD
My Color Card printer uses dye-sublimation method for the three process
colors (YMC), while the fourth (K) color utilize resin thermal transfer.
This option is of particular importance when printing bar codes, where the
black must be dark. However, for coloured images, this effect is
undesirable.
In order to reproduce graphic pixels using only the dye-sublimation colors,
what I needs is a program or plugin that convert the pictures and photos
from the CMYK to the CMY color model. CorelDraw has such a converter, but,
as far as I know, only for uniform fills and strokes.
Thanks for any help anyone might have to offer. And sorry for my
approximative English!

Lab color or RGB. Under the File menu, select Color settings : CMYK setup...
Set the "Separation Type" radio button to "GCR", and the "Black Generation"
pop-up button to "None". Then mode convert the image mode back to CMYK. You
will have a CMYK image with a blank black channel.
Salut!

Have you loked at the manufacturer's website to see if other people have had
similar problems, or if there is a driver update available?
If you have the image as RGB, converting to multichannel creates CMY
channels. However you can not print a colour composite from multichannel
mode, & most file formats don't support it.
You could create an action to generate a CMY tri-tone in photoshop. It would
be very awkward to edit in this mode though & it would take a lot of
practice to get good results
You might also be able to adjust the CMYK conversion options, so that no
black is included in the eventual conversion.
Are you sure that the printer is actualy taking the data as CMYK, & not RGB,
as if it is converting the data its self, then I doublt you'll be able to do
anything to change it.
