Working with density curves
1 Click Setup>Density Adjustment.
The Density Calibration dialog box appears.
2 Highlight a density file and then click Edit, or click New to create a new density file.
The Density Adjustment dialog box appears.
3 Select a channel to edit from the Channel list.
4 Edit the curve as described below.
Adjusting the Density curve
The density curve translates input dot values read from the file into output dot values that appear on the printed media. The Density
Adjustment dialog lets you make precise adjustments to the density curve by adjusting color channels individually, or by
simultaneously adjusting all channels. You can save settings you create as .den files. In this way, you can build a library of density
files for future use.
The horizontal axis (left to right) and vertical axis (bottom to top) represent density expressed as a percentage of coverage. If you
do not adjust the density curve, or if you click the Reset button, the density curve is not a curve at all, but a straight line. This means
that no adjustments have been made- a 50% density magenta value read from the file will print at 50% coverage.
To edit each color channel individually
Click on the Channel list to select a color, and then edit the curve by clicking and dragging points on the curve to a new value. To
delete a point, drag the point off of the top or bottom of the chart.
To simultaneously edit all channels
You can adjust all channels at the same time by modifying the curve in the same way, and then clicking Apply to All. Keep in mind
that any modifications made to all channels will override changes you may have made to the individual channels. Click Reset to
return the density curve to its default setting.
