Andrei,
From "Photoshop in Black and White" Jim Rich & Sandy Bozex ISBN
1-56609-189-6
To make your own calibration ramps
Make a new file, 8"wide by 1" high.
Select Grayscale, and 72 dpi.
Then with the foreground color set to the default 100% black and the
background color set to the default while, use the Gradient tool in
the tool box to create a ramp.
Then select Image: Map, Posterize from the menu and posterize it in 21
levels if you want 5% increments. Now you have a ramp you can send to
an output device to check calibration. The value requested in
photoshop should be the value read by a densitometer.
of course you can use any size or resolution to suit your needs. Even
posterize it to 101 levels for 0% to 100%.
I hope this helps, Jeff
