There are people who use this forum that could help but I think you are going to need to provide a bit more detail for anyone to help you.
Do you allready own the machine or are you thinking about buying one.
Is the job for indoor or outdoor use, the novajet has a very short lifespan outside unless you intend to laminate.
What material will the print be on and will it be mounted in anyway.
These are all questions I would be asking before I started giving tips on how best to complete the job.
