Resolution of the Watermark

[Sigmund]

Hi,

we use the JS Report designer in our software to design reports. For sending emails, we use the dotnet to generate the report.
The watermark shows correctly in the JS Designer and the standalone designer.
When i generate the Report with the dotnet version on the production system the watermark is rendered bigger, so the right and bottom content are out of page. The same report works on my dev system.

Does the render resolution of the Watermerk comes from a Operating system setting? Can i set is to a constant?
I cannot provide an example.
