I had a client bring me a coin to scan, we scanned it cleaned it up then made many additions to it. The client used us for thier first t-shirt order, and raved about the quality and design work. We never charged a design fee of signed over rights for this new design. The client came back to us for changes to the design for a new order. Now I find out they may be taking this design to a different printer. Can I copyright protect these two new designs? I have read much on this forum about this but am not sure if I can do this or not. What do i need to do to start the copyright process on all my wifes designs. She has also started her own clothing line with her own designs. I would like to try to protect them if I can.
