The QM10 solution includes a third-party application called ADLIB. This application is used to do part of the document conversion process, when converting documents in QM10.
When the "Adlib Evaluation" watermarks appear on your converted documents in the Validation environment, it means that the licence key for the software has not yet been entered.
This commonly happens during QM10 update projects where we are migrating to more recent version of ADLIB.
Once the project is completed, the configured watermark of QM10 will be used again.
