Image quality Office plugin

[intellimade]

My customers requirement is to make an Office Word document, enter text input which differs each period, put some Cognos graphs in there, and update them periodically.

The problem is: the image quality of the Cognos graphs in Office is really not sufficient. They look compressed and vague.
I found an old request on the IBM site from 2013, saying this is feature by design.

Anybody familier with above, and how would you accomplish the above?
Since there are 50 graphs app. copying them everytime is not an option; and the customer needs to enter manuel text which differs every period (and isnt in the DWH).

Thanks!
