I have a 300-page Pages manuscript composed of individual PDFs in full color.
How can I desaturate the document [change color to B&W]?
Is it possible in Preview in MountainLion, e.g.?
iMac (27-inch Late 2009), OS X Mountain Lion (10.8.4)
Open a copy of your PDF with Apple ColorSync Utility (Applications/Utilities). At the bottom of the window, you will see Filter on which you will have a choice of black and white, or grayscale. This will change all of your images in one swoop when you click the apply button.
Thanks, Viking…it did what you said, but didn't give me needed results…
My fundamental issue is to compress 1.3GB in Pages to under 400MB as a PDF...
Using the Print function I get it down to a PDF of 517MB…if I move from Pages to Doc [136MB] to PDF [118MB] it is TOO compressed and I lose sharpness when CreateSpace prints it.
Any suggestions for compression?
It's a 300-page manuscript with each page a separate PDF.
Thanks….walter
BTW I'm printing the 3rd volume of my weekly Potpourri blog…an item in Potpourri follows:
Viking raiders fully deserved their reputation for sensuality and recklessness. In 1012, e.g., when they feasted with the captured Archbishop of Canterbury--held for ransom. It got out of hand and the Archbishop was pelted to death with the bones of the animals eaten at the banquet. --Daniel J. Boorstein
I would hope that you have discovered the File menu ▸ Reduce File Size in Pages, before you initially made it a PDF from the print function. The ColorSync Utility also has a Reduce File Size, however again, your resolution may suffer, or it may not. Give it a try on a copy of your PDF based on the first sentence here. I just took a Pages v5.2.2 document with a single PDF image (from jpg) in it from a 500K PDF down to just 27K.
When I used Compress File Size in the File menu on Pages, it gave me a zip file [1.01GB down from 1.03GB] which I couldn't turn into a PDF. Ideas?
You're correct: ColorSync damaged resolution.
[I hope you didn't take my Viking info personally…I appreciate your helpful efforts.]

Have you double-clicked that zip file to see what is inside?
We are out of the convenient, non-time consuming options. You may be faced with individual reduction of the images that went into those 300 PDF files that were embedded into your Pages document.
Sorry for the delay in responding…[we put our dog to sleep and caring for 93 YO mom]
Finally today I got to dealing with the issue and cut 15% from the book:
from 306 pp. to 264…that solved the problem of CreateSpace's size limit for a PDF.
Now I'll see if both the b/w and color versions come out sharp and clear.
Thanks for your help along the way…walter
