You can get Stouffer step tablets from www.darkroom-innovations.com. I just
got the 35mm step tablet with 21 steps, .15 density/step (uncalibrated), for
$25.95 with ground shipping (only took a couple of days). This will give
your scanner a good workout. My SS4000 bottoms-out around the 19th step.

The Stouffer tablets are photographic silver, so they are pretty neutral.
The Q60 gray scales are not truly gray - just look at the L*A*B* values in
the data file to see how much your Q60 deviates.

You can get Kodak brand step tablets from www.tiffen.com. Look in their
Kodak Professional Accessories catalog. They have calibrated, but they're a
lot more money.

Rgds,
Cliff
