cmyk file from indesign to grayscale

Hi

have 100 page in file in indesign cs2:

what the bast way to convert cmyk file from indesign to grayscale?

thank

You can do this in the PDF by Acrobat Professional (here 7):

Tools > Print Production > Convert Colors > CMYK: Convert
Choose a Gray Profile, for instance Dot Gain 20% for Coated.

I'm using neither Gray DotGain nor Gray Gamma but a Gray
Profile which is derived from a standard profile.
ISO Coated delivers Black Ink ISO Coated in Photoshop.
Unfortunately such a profile isn't accessible in Acrobat.

Hi Gernot

this it's only away!? i dont have acrobat...

thank

Please ask in the InDesign Forum:
<http://www.adobeforums.com/cgi-bin/webx/.ee6b33c/>

As far as I remember it has been discussed there.
No alternative (besides going through Photoshop).

If this is high quality print job the best way is to do this is convert each image in Photoshop so you will has the best contrast.

print a PDF out of In Design using the color management upon export. Select your 20% dot gain profile as the destination.
