The SOLABS QM solution includes a third-party application called ADLIB. This application is used to do part of the document conversion process, when converting documents in SOLABS QM 10.
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 SOLABS QM update projects where we are migrating to more recent version of ADLIB.
Once the project is completed, the configured watermark of SOLABS QM 10 will be used again.
