Is there a way in Adobe Professional 7 to convert a color scan PDF to a B&W PDF file? TIA

Just great…Chicago politics has spread to all 57 states.
They told me if I voted for John McCain, my country would look like it is run by people with a disturbing affinity towards fascism. And they were right!

open the .pdf up

nake sure the acrobat window is active

press alt and prt scr

open up photoshop

choose new file

then paste

crop what you need

convert to greyscale

save as a jpg

open up acrobat professional

convert the jpg to .pdf

unless you have the file the .pdf was created from you can't modify it.

Easier way to do it within Acrobat Pro 7:

Open PDF

In "Tools" menu, go to "Print Production" then "Convert Colors"


If there are any spot colors in the file you'll need to go to Tools-Print Production-Ink Manager and check "Convert all spots to process"

Harold's way works well too since Photoshop will open .pdf files just fine (be careful with the resolution though, if you want it to remain high make sure you set the DPI to 300 when you open it)  However if you have type and vector objects you want to remain type and vector you want to stay away from Photoshop.

Charby's method ... well thats a lot more work then necessary ... plus JPEG compression degrades the image. Cheesy

Thats not 100% accurate

with Acrobat Pro, you can do some limited editing to any PDF (unless the security settings forbit it).

If you have Adobe Illustrator, you can open a PDF and edit it quite extensivly.

Plus there are some other 3rd party programs that can hack PDFs to various degrees.
