Hi Karen
This is a theory, but I would say that photo type paper would be best, as it is shiny and when ever I've printed a photo, I have to be careful not to smudge the ink. Also I would have the printer set to 'best quality' as it uses more ink I think, then have the wooden blank as close to the printer and do the 'transfering' as quick as possible. A paint roller or ink roller might be good too.
Hope this works, (if you try it) I think it's a great idea. Would you show some oictures if you do it please?
