Yes, pictures can be printed direct on to wood but you need or will require a company who have specialist printers that are able to do so as this is not something that you can do with your traditional office printer.
When printing pictures or images onto wood this is something that we can do, the main requirement we require is that the wood is flat to make sure that the image is printed on as clear and in the best quality.
We have printed onto different types of wood for different projects and depending on what the print is for sometimes dictates the type of wood we have used. For invitations we have printed on 3mm thick plywood that really works well or for more special images these can look well on a thick piece of oak.
Anyone who is after a quality piece of wood to have a picture printed on then solid Oak is a firm favourite. Oak is the most popular type of wood that people look for when they are after a quality piece of timber, in general if you ask someone what is the best type of wood then Oak is the wood that they will come back with.
