Creating Grayscale PDFs

It's very frustrating that there is no easy way to create a grayscale .pdf file. You can print in grayscale; why can't you create a grayscale .pdf? Anyway, for those times when you need to send a client a grayscale .pdf, there are steps you can take to make your color .pdf grayscale.

You'll need Adobe Acrobat and Acrobat Distiller.

Open your .pdf in Acrobat and choose Save As. Change the format to PostScript and click on Settings. Under Output, change Color to Composite Gray. Save the .ps file and then drop it into Distiller to remake the .pdf. Voila, a grayscale .pdf.
