everyone....A while back a good flatbed that was on sale was talked
about by some of you. What was that scanner? I need a good flatbed
scanner and I was wondering if that scanner would be appropriate. I
already have a slide scanner so I would not need any thing like a
slide adapter that some flatbeds come equipped with. Any
I recently bought a ScanMaker 8700, the Pro (or Design?) version
with extra software, for $1,000. According to my personal (and
somewhat subjective) testing:
o It has a similar Dmax and cleaner greyscale histogram than the
$3,500 Agfa T2500, but significantly more shadow noise.
o It's reflective Dmax is about 2.5 but usable dynamic range is
1.5 to 1.9 depending on what's being scanned.
o It's transmissive Dmax is at least 2.8 almost all of which is
usable, again depending on the target.
o This is far less Dmax than the typical specs, but is
supposedly excellent real-life performance for this class of
o It's capture of a smooth greyscale gradient is excellent,
implying that it's A/D conversion is good.
o It's sharpness across the full legal size scanner bed is very
good, without the "sweet spot" that many scanners have of
higher sharpness in a band down the middle.
o It's evenness of tone across the scanner bed is excellent (i.e.
it's not "bright" down the middle and "dim"
towards the edges).
o It's alignment between the RGB CCD sensors seems excellent
across the entire scanner bed.
o I haven't been able to determine whether it lives up to its
2400 dpi resolution claims. It resolves some pretty small
details, like the microprinting on US currency or on the signature
line of my bank account checks and some resolution targets I have, but
none of these are calibrated so I don't know how good a performance
I'm actually seeing.
o It comes with transmissive and reflective IT8 color calibration
targets and a proprietary ICC profile generator which seems to do an
excellent job of creating scanner-specific profiles. The quality
of color management seems excellent.
o By and large the ScanWizard Pro software works very well and
has all the control you could wish for. It also allows you to
select multiple areas on the scanner bed and scan them as separate
images in a batch operation.
o It also comes with SilverFast Ai 5.5, Genuine Fractals Print
Pro and an OCR program but I haven't worked with these yet.
o It has a separate, internal tray for transparencies and a
variety of adapters. But you asked only about reflective scanning so
I'll stop here about transparencies.
o It has both FireWire and USB interfaces. I use Mac OS 8.6
which works great with Firewire. I haven't tried USB. With
the OS, VueScan (from hamrick.com) works only with USB, not
o Except for the one flaw of being noisy in the shadows this is
an excellent scanner and I've made some beautiful scans with it.
