I publish files to pdf only as a proof sheet for our customers to review. The proof quality doesn't have to be the best. We don't print from pdf's anyway. I've been experimenting with different settings to get the smallest pdf file size possible. I've come to notice that CMYK is smaller than RGB. Seems kind of backwards to me but whatever. Trouble is most clients are happier seeing rgb colors in the pdf. All my pdf's are password protected whereby only allowing low res printing. I also set it to convert all fonts to curves. Once the pdf is created I open the pdf in Acrobat Pro and hit a corel macro to further reduce the size. This method usually takes a 450k file down below 200k. If I use "document distribution" and only input the password parameters the same file is 300k and again reduce by Acrobat Pro, it goes down to 75k.
Anyone have any input as to what will make for the smallest file size? How about what acrobat pro does to further reduce the size? Be nice if I could skip that step altogether.
Keep in mind I don't have any problems with the process I use as it's all done with macros very quickly. Just seeking advice on how to reduce file size.

Here's an update just for giggles. I now have two separate macros to create my pdf's for proofing. One if color is critical and another if it is not (see attached). In this case red is red notice that file size is only 43k. The other macro uses rgb as pdf colors and it's 198k. We keep a file on the server that is just for proofs to be emailed out. Right now we have 3,250 files.
Size does matter lol

I agree with Jeff, CMYK should be larger than RGB (4 channels instead 3).
Under "Configuration" go to the "Objects" tab, choose JPG file compression, a big amount of compression (more than half) and reduce the resolution of bitmap (if the file include bitmaps). remember that was only for view purposes, not for print. bw the PDF should include always the Color Profile. if you don't include the color profile, the file will be smaller but the color could change and the result maybe was wrong. Although you use RGB color mode, you should enable color profile on the PDF
