Hello Ajay, in this case I can't help you because I don't understand your question: it's too specify and overtakes my little knowledge of ghostscript and advanced printing. However I suggest you two useful discussions on stackoverflow: Embed ICC color profile in PDF and CMYK Overprinting and Knockout in Ghostscript.
