What's the deal with the color info after you've grayscaled an image that was CMYK? Shouldn't it just be varying amounts of black?
Sending something to be printed in a newspaper for the first time and wondering if I can just export a PDF in greyscale from InDesign(How?) or if not, and I make all the components that I'll place into black and white in Photoshop, is Image>Mode>Grayscale a good way to do it?
The paper prints some things in color, so I wouldn't want it to actually use any of the other color inks if I'm trying to do black and white, correct? There is going to be black in the piece and so I made a background layer that was CMYK=0,0,0,100. Is that the right way to go about it?

Re: Grayscale has C,M & Y? B&W newspaper printing?
Thu, May 24, 2007 - 7:37 PMin my experience, the best and most error free way to end up with a strictly black and white or grayscale PDF, is to make all your imported images either 1 bit black and white images, or grayscale. and yes, image>Mode>Grayscale through photoshop is the way to do that.
i believe there is an option somewhere in Acrobats print settings and options that you can set to grayscale, but it's not always as reliable as the option above.
only reason you would need a background layer of 100% black only is if you're doing a full reverse. as long as all your elements, imported and otherwise, use only black, whether 1% or 100%, it should work just fine and export as a strictly black and white and/or grayscale PDF. and it's easy enough to check. one your PDF is made. just look at separations under print production in Acrobat.
