Many kudos to Banzif, who scanned that tank screenshot in PCGamer at very high resolution and sending it in. After a quick recompress and resize, I've posted them here:
The first one is the scan as I recieved it, and the second is the scan after being scaled down and smoothed out. Of course, both images suffer from the print resolution, but the second one is almost close to the screenshot quality we're used to.
