[MiKTeX] Generate a grayscale ps document from a document with colored graphics

[Stefan B. <sbi...@ul...>]

Hello,

I have a latex document with colored graphics. For some reasons, I need 
the whole or most of my document with my figures in grayscale. My 
questions are:

1. Is there a way to do this in Miktex when you generate the document or 
later on, to convert the colored dvi or ps document into a grayscale 
document?

2. Can I define somewhere that the document should be in grayscale 
except for some special pages?


Thank you very much in advance for your help.

Stefan
