Elia,

you can simply go to the "image" menu and change it to CMYK. The reason it looks
different is that the RGB image on the screen is much better (has a wider gamut)
than what the printer can render. The CMYK is not only separated into 4 colors
(Cyan, Magenta, Yellow and Black) but also narrowed down to what the printers
can put out. You may try to manipulate the CMYK image.

Many new printers can now print from RGB reducing the gamut automatically. If
your can not try to find a newer printer driver. Kodak may have it. See their
web site.

Also if you print on normal paper (I am not familiar with that printer) the
result is dull compared to a glossy, coated paper.

Good luck.

Subject:  RGB to CMYK?




Dear Users,

I have RGB images that I'm trying to print on a disublimation printer
(Kodak XLS 8300).  The printer will only print a CMYK version of the
images.  In the conversion from RGB to CMYK, the colors in the image change
in a manner that is far from desirable, to say the least (My blunt boss:
"These images are crap




à").  In addition, the journal we want to submit to
requires an electronic version of the images, and they want them in CMYK.
My question is: How can I make up for the changes in color that occur as a
result of the conversion from RGB to CMYK?!  The image processor I use is
Adobe Photoshop.  Please, any suggestions will be greatly appreciated.

Thank you,
Elia
