Ok, I've spoken with a very knowledgeable person at Nazdar and he said that my solution was very easy since the jacket is PVC coated and the VF series ink is perfect for this type garment. So anyone wanting to print on anything PVC coated has their answer. Sorry for posting the question before doing the research but I figure this will be here for others that might have similar problems.
