Or you could try a modification of*'s option #2, but instead of using
Screen or Print settings for creating the PDF, modify the downsampling and
compression settings by first selecting one of those, then using the "Edit
Job Options" button and select the "Compression" tab page. Then you could,
for example, set it to use bicubic downsampling for images above 150dpi to
150dpi, which is probably the lower limit for decent quality printing on a
desktop printer, and set the compression quality to medium, or whatever.
Then "Save as" and give your custom setting a name to use in the future, and
experiment with different settings to see what tradeoff you get between PDF
file size and printed image quality. Of course, the more TIF images used in
the document, the greater the file size, so you may want to develop some
rule of thumb for what percentage of average page area can be images, versus
text or graphics, depending on document length too. If you are distributing
the PDF file and not the PM file, then there's no need to change the
original high quality TIFFs placed in the PM file, unless you need to
actually change the image dimensions or scale them down relative to the page
size, which may help to reduce the file size, as* pointed out,
especially for those nearly full page images.
Anyway, I would definitely look into tweaking those downsampling and
compression settings in the Acrobat distiller to get your best tradeoff
between file size and printed image quality, and then you could avoid having
to keep two different versions, when a full 300dpi version is probably going
to be too big anyway.
That's my 2 cents,
