Excuse my question but there is something I don't understand 
here... I'd like to be sure we are not scratching where it doesn't 
itch. 

PDF files don't show images at a better resolution, they just 
"encapsulate" and show them. So, if you have a 2000x2000 px jpg, 
putting it inside a pdf will not add resolution (nor lower it, if 
it's not compressed), but just add a wrapper around it. The 
resolution is a property of the image file.

OTOH, different image formats do change the quality: jpg and 
(some) png are lossy formats while tiff is looseless. 

So what kind of images are you talking about? Are they produced by 
you and your team (and using what tools/methods), scanned from 
physical artifacts, or taken from other sources?

Maybe there is no need to do all this pdf magic.

Again, this is quite similar. You can produce pdf from svg: both 
are vector images and are resolution independent. But emacs con 
show svg files directly (see 
https://www.emacswiki.org/emacs/EmacsSvg).

Best...
