I would be very careful with Allure Metal sheets. Those can possibly damage your printer if you don't do the settings properly and they can be finicky at times when loading.
We've tested those before and were good the first round of tests. The second time (before we almost agreed to the manufacturer to sell them) it became a hassle feeding them in both the P800 and P5000 (worked great the first time), and each time they attempted to feed, we received skew issues or problems of it not being fed correctly. After a handful of attempts again, we agreed not to sell them in case customers got them from us and had issues (or worse- damage their print head or printer). Since those plates are not authorized by Epson, it's a chance to take if you want to attempt it.
Quality is good and nice for direct printing, but can "surely" be a hassle down the road. At the moment, I would attempt Dye-sub; even though there are a few more factors, but this way it's under warranty and certified by the manufacturers of the products (especially printer).
