AW: display and print different image quality - solved

[Tiemo Hollmann TB]

Add FYI: Thanks to William, I found another more straight forward approach.
I still have two logo images, a small dimensioned one for display on my card
and a larger (hidden) one for containing a better resolution for printing in
a larger scale. Now I export a snapshot of the larger img to a local and set
the text of the small img to this local. Using this workaround the small
displayed AND larger printed quality of the small logo image is fine.
I don't know why, but the result of the print resolution differs completely,
if you set the text of the small image directly to the text of the large
image (bad resolution) or if you set the text to the exported local. Having
set the resizequality both times to best before.
Thanks
Tiemo
