I have an order for black hoodies and they want army color green printed on it....not the problem. They want the same color printed on a 100%black polyester jacket that they will be providing. I've never printed on polyester and I'm wondering any info I may need. Can I use an additive to the plastisol green I use on the hoodies? will I need to print a white base? what would be the cure time? I also have no idea on how to price this because I have never printed polyester nor has anyone provided the garment for me before. Any ideas? It's for my boss'
