there are two things in postscript,
CRD = color rendering dictionary (like A2B I think)
CSA = color space array (like B2A of a ICC I think)
both are from postscript level 2
CSA only allow three chanel input, so a convertion from cmyk to cmyk dosn't work. this limitation was stoped with CPSI-version 2017. postscript 3 rip are working fine with three and for chanel data.
