12. If PANTONE colors are inaccurate, refer to the Color Management chapter within Using your

13. Color accuracy using EPS or PDF images in page layout applications such as Adobe InDesign and
QuarkXPress do not support color managment of EPS, PDF or Grayscale files.
If these types of files have to be used, try to ensure that the EPS, PDF or grayscale images are
already in the same color space that is to be used later on in Adobe InDesign or QuarkXPress. For
example, if the final objective is to print the job in a press that follows the SWOP standard, at the
time of creating the EPS, PDF or grayscale the image should be converted into SWOP.
14. Check the procedures described in
Colors are inaccurate on page 175.
NOTE: The HP LFP Knowledge Center is an excellent source of color accuracy information, the
database includes step-by-step procedures on achieving the best color image quality when using
various applications. Go to
