Title: 6-color 96 bit scanner available from HP. Any good for Prism? Post by: crenedecotret on September 11, 2009, 09:19:01 PM I'm currently using a Canon LIDE 60 with reasonable results.
The only strange issue i've ever had was grayscale always having a green tint in the shadows. Ordered a new IT8 from Wolffaust and never looked back. I just saw an Office Depot flyer advertising a 6 color scanner. It supposedly used two different kind of red, green and blue. Their explanation is that different lights produce different effects on pictures and this is to correct this. (sounds like a marketing description for metamerism if you ask me) They say that combined with 96-bit color depth, this is a much more accurate scanner in terms of color reproduction. Sounds quite good to use with Prism. Has any one ever tested this (Scanjet G4010)? I won't rush out and buy a new scanner since i'm already getting good results, but I thought I'd share the info.

So, if two lights produce different effects (well, duh, they're not telling us what we don't know) are they just using two different light sources? Is their light source not full spectrum? Just one caution. I'd try before I buy. I have run 48-bit and 64-bit modes with Vuescan on the Epson. At 96-bit with any kind of scan resolution you may as well start it just before you go to sleep for the night. AND, you had better like large files unless they have a new algorithm going on. Dunno.

There is a test done by Image Engineering of the HP G4010 or G4050 and Epson scanners etc. The color accuracy was higher but not that significantly higher. I do not think the scan time was also compared which is much longer if you need two scans to get the result. Another thing to mention is the register between two scans, if off it will influence the detail sharpness. In itself it is an interesting technology. On full spectrum: hardly any flatbed scanner has a full spectrum lighting. They are usually designed to scan CMY(K) composed originals (Photos, Films, Prints) and not nature and within that limitation they perform well. In that sense the two HP models are actually better as the two fluorescent tubes compensate their individual spectral output, not just overlaying the spectral curves bur some smart software can do better than that. Whether it is worth it has to be distilled from the 3rd report on this page:
