Colors are inaccurate
If the colors of your print do not match your expectations, try the following remedies:
1. Check that the paper type you have loaded corresponds to the paper type that you selected on the front
panel and in your software. At the same time, check the color-calibration status. If the status is
RECOMMENDED or OBSOLETE, you should perform color calibration. For the Z6800 see
Color calibration
on page 101 and for the Z6600 see Color calibration on page 105. If you have made any changes, reprint
your job if the problem has been solved.
2. Check that you are printing on the correct side of the paper.
3. Make sure that you are using the appropriate print-quality settings. See
Select print quality on page 83.
If you have selected the Fast options, you might not get accurate colors. If you change the print-quality
settings, reprint your job if the problem has been solved.
4. If you are using Application Color Management, make sure that the color profile that you are using
corresponds to the selected paper type and print-quality settings. If you have doubts about which color
settings to use, see
Color management on page 95. If you need to create a color profile, for the Z6800
see
Color profiling on page 102, and for the Z6600 see Color profiling on page 106.
5. If the problem consists of color differences between your print and your monitor, follow the instructions
in the “How to calibrate your monitor” section of the HP Color Center. Reprint your job if the problem
has been solved.
6. Print the Image Diagnostics Print. See
The Image Diagnostics Print on page 72.
7. Consult the HP Knowledge Center at
http://www.hp.com/go/Z6600/support/ or
http://www.hp.com/go/Z6800/support/ according to your printer model, for step-by-step color
assistance with different software programs (English language content only).

Colors between different HP Designjets do not match
If you print an image on two different printer models (for instance, on an HP Designjet Z6800 printer series
and an HP Designjet 5500 printer series), the colors of the two prints might not match well.
