image compression in digital signature documents

[BruceLevan]

I use a digital signature from another company and I will be switching.

My reports contain large JPEG images from the electron microscope. Each image is over 5 MB. I sign the report (with the images) with a digital signature and send it to the client. But the file is compressed far too much and the images have lost all the details. A file of 20 MB gets compressed to less than 2 MB. I cannot control the amount of compression with my current digital signature provider.

If I switch to Adobe Sign, does it provide anyway to control the compression of my digitally signed report?

Alternatly if I buy Adobe Acrobat and Adobe Sign, can I control the compressiion of my digitally signed report?

So Adobe Acrobat compresses my e-signature when I sign and I have spent a while morning trying to resolve in every way possible, no success. No advice online, no support or help and no resolution to this frustrating issue.
