Thanks again for the suggestions. Sure, I understand that there is no way to totally eliminate plastic in the workflow, so I am just trying to figure if there are ways to minimize it. Also, I tend to be more okay with cellulose acetate than polyester or polyethylene, ha. I found a very informative page dealing with alternative printing processes, if anyone else is interested in perusing it.
