Problem that we have had trying to get away from screen printing these kinds of labels is we use ecosolvent (which the go to technology for digital printing labels) for wide format and there aren’t any of the durable films required for aerospace applications available for that inkset. I think latex is better for that but I don’t know the tech well and I’ve heard not great things over the years. Since we are a contract print shop, I charge what I need to charge for screen printing and if they don’t want to pay, then I don’t need the business. The certs and conformance information required is a huge pain for us so we charge document fees too. We are looking to get into UV LED technology so we can print on durable materials digitally. Problem is, that’s going to be an expensive endeavor if you are just an in house print shop. As for cutting, the edge plotters are great bc of the pin system. Keeps the registration tight. Regular plotters are never going to be as accurate so you need to go to flat bed digital cutting which is another expensive piece of equipment. You can get everything used but I would still expect to spend $100k to get what you need.
We still have an Edge 2 and plotter that we use specifically for short run durable labels, but you are right, every week it gets more expensive and harder to find the supplies.
