Colors are inaccurate
If the colors of your print do not match your expectations, try the following:
1. Check that the paper type you have loaded corresponds to the paper type selected in the front
panel and in your software. To check on the front panel, use the View loaded paper key . At
the same time, check the color calibration status. If the status is PENDING or OBSOLETE, you
should perform color calibration: see
Color calibration on page 74 . If you have made any changes,
you may wish to reprint your job in case the problem has been solved.
2. Check that you are printing on the correct side of the paper.
3. Check that you are using appropriate print-quality settings (see Printing on page 59 ). If you have
selected the Speed or Fast options, you may not get the most accurate colors. If you change the
print-quality settings, you may wish to reprint your job at this point in case the problem has been
solved.
4. If you are using Application Color Management, check that the color profile 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 73 .
5. If the problem consists of color differences between your print and your monitor, please follow the
instructions in the “How to calibrate your monitor” section of the HP Color Center. At this point, you
may wish to reprint your job in case the problem has been solved.
6. Print the Image Diagnostics Print. See The Image Diagnostics Print on page 172 .
7. Try using the color adjustment options to produce the colors you want. See Color adjustment
options on page 77 .
If the problem persists despite all the above actions, contact your customer service representative for
further support.
Color accuracy using EPS or PDF images in page layout applications
Page layout applications such as Adobe InDesign and QuarkXPress do not support color management
of EPS, PDF, or grayscale files.
If you have to use such files, try to ensure that the EPS, PDF, or grayscale images are already in the
same color space that you intend to use later on in Adobe InDesign or QuarkXPress. For instance, if
your final goal is to print the job in a press that follows the SWOP standard, convert the image into SWOP
when you create it.
