How can I get rid of the "Evaluation" watermark which appears on my pad?
The evaluation watermark image appears if you do not specify a licence key in your application code or if you use a non-Wacom signature pad.
The solution is to insert your licence string at the appropriate place in your application code.
If you are using one of the non-Wacom signature pads which we support such as the ePad-ink this needs a special licence which must be purchased from Wacom and applied within the code.
If no licence is applied, then by default a watermark saying "Evaluation" will appear on the signatures.
A production licence for the standard Signature SDK and SigCaptX is provided in the GETTING STARTED document alongside the sample code at https://github.com/Wacom-Developer/sdk-for-signature-windows
The need for a licence key when using Wacom signature devices was removed with release 1.23.3 of the Signature SDK but reintroduced with release 3.13.2.
If you have an older release than 1.23.3 then removing the licence string from your code will not resolve the issue.
From 3.13.2 until 3.20.3 a short-style licence is required and the later, long-style licence (as provided on GitHub and on developer.wacom.com) will not work.
If you are using a release within the above range and do not want to upgrade your SDK please raise a support ticket (see link below) and request a short-style production licence.
If you have any further queries please raise a Support Ticket.
