command to convert pdf to eps with no loss in resolution

I want to convert a .pdf file to an .eps file of the same resolution on a unix based machine. If I use

"pdf2ps file.pdf file.eps"

the resulting .eps image is not the same as the .pdf image. Colors are much lighter as compared to the .pdf one. Also, the size of file.pdf is 115 KB, and that of file.eps is 3.6 MB.

Can someone please guide me how to properly convert a .pdf file to .eps file. I am using Mac OSX Snow-leopard (10.6.8).

Thanks M

I would recommend looking at this question here, but to summarize the part I used to do the same thing is:

pdftops -eps filename.pdf
