I found a cool texture that I wanted to use in a National Geographic magazine. The problem is that once I scanned I get the crosshatched, moire artifacts. I know there is several ways to get rid of this in Photoshop, I scanned at 300 dpi and downsampled to 150 dpi and it helped, I also tried to use the median filter but it was a bit to much, even with the unsharp filter afterwards. Any suggestions???
