RobertIt is almost impossible to get the cards perfectly straight when you scan them, after you do the scan you need to import the image into Photoshop where you can turn the image anyway you want with extrme accuracy. If you are going to print out the images I suggest you scan in at 300DPI if you wnat to post the images somewhere on the web then you need 72 DPI becasue that is the maximum for any computer monitor. After printing your image you can compare it to the original and then go back into photoshop and make color corrections.
Hope this helped it takes a little bit of knowledge but it is easy.
