First of all thank you very much for your attention and tips!!!! Sorry for my English, it’s not my language but I try. I was thinking about a low relief kind of signature. I’ve seen it but have no idea how to do it. For metal jewery, for example, there are stamps that are hammered on a piece to insert letters etc. I thought for resin there could be some way to get the same effect. If you have any idea of how to do it, please let me know. Thanks again for everything!!
