Problem summary

• ****************************************************************
  * USERS AFFECTED: All GDDM users producing PostScript output.  *
  ****************************************************************
  * PROBLEM DESCRIPTION: 1. Gray colors (numbered 121 through    *
  *                      150) are printed slowly and appear      *
  *                      muddy. 2. RGB colors are incorrectly    *
  *                      converted to CMYK format. 3. Level-1    *
  *                      PostScript files with many image        *
  *                      components can cause stack overflow in  *
  *                      the printer.                            *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  1. RGB greys were converted to CMYK colors with non-zero CMY
  components; CMYK colors were only converted to PostScript
  "setgray" format if the CMY comopents were all equal, and the K
  component was zero. 2. RGB colors converted to CMYK format did
  not have the K component subtracted from the CMY components. 3.
  PostScript level-1 images left unused values on the stack.
  

Problem conclusion

• The problems are fixed by PTF.
