That's a lot of work, I made my zip pdfs and then on the output pdf
I jpg'd it, When all is said and done my folder is 3gb!
it's just a 12pg plus cover

Thanks I almost ruined the file!!!

Whats their privacy policy?  just kidding

Hey Thanks! going to check it out!

you just reminded me we have Bates Nut Farm right up the road here!

Order from here and see if they can overnight it. It's only about 6-8 hours from San Diego. And no, Sierra Nut House is not an asylum.

If quality is of any concern, I wouldn't compress anything. What I might do, in a rare pinch, is make two files. One that is an all raster pdf not compressed, and one that is all vector pdf. Drop both files into Command Workstation and impose them both identically. Then, make the raster file a MASTER and treat the vector file as an IMPRINT. CWS will process the file much more quickly in this fashion and you won't lose quality.

ZIP is a lossless compression if you use the maximum quality setting so it should not degrade anything.

What if I do a zip pdf after the jpg pdf?
see above

yeah doing that keeps the images jpg so I'm assuming that is bad

Ah! so if I make a pdf and then put that in a saddle stitch template
and make a new pdf it will lower the quality?

see that is good info, I didn't think of that, I thought only editing the images would cause a problem

Thanks David!

That was good info, sheesh so many times I didn't do that 
I didn't order as it wouldn't get here in time for mothers day for my Mother in law
sheesh now I have to come up with something else 

jpeg compression is a lossy compression, meaning it discards pixels (removes redundant pixels) every time it is resaved.

If you were to open and resave the pdf multiple times, you would see a difference between the 1st save and the last save as far as image quality is concerned.

You know those super huge files?
One day the copy guy was having a problem with a file
and I resorted to making a .jpg compressed pdf
This makes a considerably smaller pdf and it worked.
I would never edit a .jpg pdf, and I name it 123456_jpg.pdf
I did a test and don't see any difference in the prints.
Is there something I don't know that would cause a problem?
would there ever be a color change?
I have been doing Zip compressed so many years now.
This is helpful on large files that need to be converted to cmyk in the pdf process also,
device cmyk makes a huge file of big files.
I have the image quality to maximum on my setting
