HP's G4050 flatbed scanner employs a novel two-pass technique to extract maximum detail.
HP G4050
Desk Dominating
If you like your scanner to dominate your desk, the G4050 could be for you, being easily larger than the already-big HP G3010 we’ve tested. Inside the big box is a unique scanner CCD that is sensitive to six colours instead of the usual three (red, green and blue). This mode is switched off by default and the reason is a major increase in scanning time once it’s turned on.
Performance and Scan Quality
Scan quality is already quite good in standard mode and we couldn’t see a major pay back for the long waits in six-colour mode. Film scanning takes ages too and for a scanner of this price we’d expect classier film frame previewing and selection facilities.
The G4050, ultimately, promises much but doesn’t deliver a great deal extra.
