When I try to print color separations using ColorBurst for Windows, the RIP produces a composite print where the separations are re-combined. Why does this happen?

• The Windows version of ColorBurst produces the separations as a composite print that shows traps and overprint. This feature cannot be disabled.
  
  The Macintosh version of ColorBurst can be used with the Stylus Pro 7800 to produce color separations with individual layers of color per page.
