The laminate purposely used on the cards makes them REALLY difficult to scan. The result creates something that looks like a moire pattern in the finished scan.
Last attempt I scanned them in at 800dpi and then used the techniques I found here - <a href="http://graphicssoft.about.com/cs/photoshop/ht/apsremovemoire.htm" rel="nofollow">http://graphicssoft.about.com/cs/photoshop/ht/apsremovemoire.htm</a>
Even after all that, too much of the finely painted detail was lost in the process by the unsharpening and blurring. I wasn't happy with it.
