The procedure is as follows:
set color settings
Before preparing for printing:
Set up the color settings in Adobe® Photoshop®.
- Color Working Space is the critical setting.
- Adobe RGB (1998) and ColorMatch RGB are each good for graphic arts.
Set to 'Ask when opening' for all profile mismatch situations.
save photos in Photoshop
Take an image in RGB color from a scanner, digital camera, or other
source.
In Adobe® Photoshop®, convert the image to CMYK profile by making
a mode change from RGB to CMYK, with correct profiles set for monitor, Color
Working Space, and CMYK profile (identified as a 'Working Space') in the Color
Settings dialog.
File in CMYK color, save in TIFF format.
Save the file in CMYK color in TIFF format for use in other
applications.

To print from Photoshop, choose Print under the File menu, and print
directly to the HP Designjet printer.
