With Adobe Reader DC I can successfully place a digital signature in a pdf document. The private key related to the signature resides in a Qualified Signature Creation Device (USB stick with a smart card).
The produced signature is reported as valid after the signing. However, it is visually not readable as the letters in the text are placed on top of each other. Reinstalling Adobe Reader did not help. The issue persists on both my desktop and notebook computers.
The certificate appears perfectly readable on the preview screen before pressing Sign button. Here is a snapshot of the visual result after pressing the Sign button.
Configurations and versions:
- Adobe Reader DC, 2017 Release,
Version File Version 17.009.20044.25828,

I will appreciate any help in solving this issue.
Sorry for the delay in response.
Firstly, I would suggest resetting Reader preference: How to reset Acrobat Preference settings to default.
Then try customising signature preference: Custom Signature Appearances — Digital Signatures Guide for IT Let us know if that helps.
If you already have found a solution to this problem, please update the thread with your findings that will help others.
I'm having the same issue on Acrobate X Pro. It just started.
I deleted the preferences folder and the security folder as well deleted and remade my signatures, all to no avail.
