I admit I don't understand this statement.
Create a new document in Photoshop. The size isn’t critical but try to make
the horizontal about 1200 pixels. You want to view as much of
this document at 100% zoom ratio in Photoshop filling most of
the display you are testing. The color space of the document
2. Choose Edit-Fill and when the Fill dialog appears select Use:
Black, BlendingMode: Normal, Opacity 100%.
3. Choose Image-Mode-Assign Profile in Photoshop CS or
Edit-Assign Profile in CS2. From the list of profiles you need
to select your display profile. What this does is ensure that
Photoshop will simply send the numbers in this document
directly to the screen. This will aid in evaluating the display
4. You will need to select the Rectangle Marquee from the
Photoshop toolbar or simply hold down the M key. Make sure
that in the option bar the Feather is set to zero and that the
Style: pop-up menu is set to Normal.
5. You will need to make a rectangle selection in this document. It
can be just about any size but try and make it so it fills about 50 percent
of the document in the center. You will need to be able to see inside and outside
of this marquee so don’t make it too large or too tiny.
6. Hide the marching ants. This can be done by selecting View-
Show-None or by holding down the Command/Control H
7. At this point, You need to fill the entire display with this black
document so we need to go into full screen mode. The easiest
way to do this is to press the F key twice. Hide the tool bar and palettes. By holding down the Tab key,
8. At this point, you should have a screen filled with only black!
You we need to call up the Curves command. Since the
menus are hidden, you’ll need to use the Key command,
which is Command/Control M. The curves dialog should
appear. Move it over to a corner since you will want to see the
effect of the hidden rectangle marquee.
9. At this point, you will move the black curve point up one
numeric value at a time. To do this, simply press the up arrow
key on your keyboard once. The output value will change from
zero to 1. If instead the values pops up to 2, enter 1 into this
output field and all subsequent pressing on the up arrow will
ensure only one value is added. Keep pressing this up arrow
key until you can just see the separation from the rectangle
marquee. That is, you want to just barely see the rectangle. You
may need to press the up arrow key several times. Ideally, you
want to see separation between a value of 0 and 1. I can see
this on the Artisan.
Keep moving the up arrow slowly once you see the separation.
The next thing you want to do is examine how neutral each
step is. Not only should each step show the same density
difference from the last, but also each progressively gray step
should be neutral. It is not uncommon to see a gray square go
from neutral, to slightly green, to slightly magenta, and back but that's NOT ideal.
