Comment (by yohann):

 Replying to [comment:7 cehoyos]:
 > Sorry, I don't think that would help either: Is an additional fourth
 channel (with infrared / transparency information) with the original
 resolution possible?

 The scanner has very few options in that regard, it's either grayscale or
 RGB for the colorspace. No fourth channel option.

 (By the way, the scanner model is Lasergraphics Scanstation and not
 Director as I first thought)
