Has anyone ever screenprinted onto wood? I am new to this whole area in general.

I imagine I would need to get the wood very flat and very smooth. Then probably cover the surface in something to stop the paint bleeding (being absorbed into the wood and making lines blurry). And from there just behave as normal really?

All thoughts appreciated!

I have never done this so I have no advice for you. Sorry. But whatever you coat the wood with you need to be sure the ink used will bond to it.
