Raster data for Pure black text printing

[shermin]

Hi,
  One of the RIP used for CUPS is pstoraster right?So if i want to modify only the cmyk separation in my RIP,do i need to add only a patch of code for pstoraster as RIP for my device  and whether all the rest of things will be done by pstoraster???

2)How will i bring my RIP in between the pstoraster execution.?
