How can I get rid of the "Evaluation" watermark which appears on my pad?

With the Signature SDK for Windows the evaluation watermark image appears if you do not specify a licence key in your application code, if you are using an expired licence or if you are capturing signatures from a non-Wacom signature pad.

The solution is to insert your licence string at the appropriate place in your application code as explained here.

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.  Please "Submit a request" using the link at the top of this page if you need to do this.

If no licence is applied, then by default a watermark saying "Evaluation" will appear on the signatures.

A production licence for the Signature SDK for Windows "Lite" version (see link below) and its browser subcomponent called SigCaptX is provided in the GETTING STARTED document alongside the sample code at https://github.com/Wacom-Developer/sdk-for-signature-windows

The term "Lite" is explained in detail here:  How do I obtain a licence for the Signature SDK for Windows and how much does it cost?

NOTE

The need for a licence key when using Wacom signature devices was removed with release 1.23.3 of the Signature SDK for Windows 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.
