I have an 8-page document. Each page has one large photo and a text heading. Is there a way to export to pdf so that some of the pages compress their images while other pages do not? Three of the photos are low res (72 dpi) and do not look good with compression.
If not, I thought I might resample them up from within CorelDraw so they are comparable to the res of the photos on the other pages (~200dpi) and compress to around 85% jpg.

Really, nobody will notice difference if the PDF us LZW or ZIp, just a little difference of the file size because both are different algorhytms based on the same structure. The PDF will open fine on any system, no matter the internal file compression you choose.
If it's just for view and correct the PDF, you can use JPG file compression (with a few file compression) and images at 200 dpi. For hi-res printing you will need more resolution

That's interesting! A lot of articles on internet said LZW compression on 16-bit TIFFs creates a LARGER file...??? Usually they gave test comparisons, and the LZW was always much bigger. Do you have any ideas why your 'technique' of LZW settings are so successful compared to others....:-)....?

it's "larger" if you compare it with JPG file compression, but it's enough for most jobs
Seeking enlightenment. Why are you sending 16 bit tie files?
