:Oops: If you’re asking questions like that, I don’t think you understand the idea behind digital printing yet. Maybe you should do some more research, because it doesn’t sound like you have a handle for this line of work yet.
First of all, nothing much thicker than .030 will go through a VersaCamm without ruining it.
Next, inks are all transparent, unless you get a machine that prints white, which isn’t an option on the VersaCamm, as I know it. So, you can print to a light or pastel type of color, but not with accurate results.
Getting roll stock banner material in various colors is available from any banner company, but that doesn’t mean they’re good for digital printing.
Before you get your machine, go to a trade show or two and watch how the many machines do their thing. Don’t necessarily listen to the salespeople pitch, but ask your questions and see what the machines do first hand… then re-think what machine you want or need.
