When you receive a trial license key from Windward that key is coded to create a watermark on all the output produced by that license. Not just the Designer output but Engine output too.  The .NET, RESTful, and Java engines will also watermark their output to prevent commercial use of our trial licenses.

Once you become a Windward customer Test licenses will continue to watermark their output but your Designers and Production licenses will no longer watermark or protect their output.
