Under Curve Type, select one of the following options.   These 
selections affect the values boxes and the way the curves are 
displayed in the Profile Curves dialog box.  

■

Dot Area:  Adjust the curves in the Profile Curves dialog box to 
reflect dot area information. This is the default setting. 

Dot Area is the amount of area on the page the printed dot 
actually takes up.  The dot area curve shows you how much 
dot area you have versus how much you expected.  For 
example, if you request 50% Cyan, the printing press may 
print 75% Cyan in total dot area.  

■

Dot Gain:  Adjust the curves in the Profile Curves dialog box to 
reflect dot gain information.

Dot Gain is the percentage a dot grows during printing from 
what is expected.  The dot gain curve shows you the real 
percentage of each ink color versus the requested amount of 
each ink color with the percentage of dot gain.  For example, if 
you request 50% Cyan, and the printing press prints 75% 
Cyan, the difference of 25% is the dot gain.  

Under Editable Values, select one of the options.  

The first row of numbers is the default setting.  Make another 
selection as desired.

This selection changes the active percentage points (but not the 
appearance of the curves) in the Profile Curves dialog box.

■

The first row of numbers (10%, 50%, and 100%) is the default 
setting.  These percentages let you adjust colors in a light area, a 
middle range, and in a dark area.  

■

The second and third rows of numbers (40% and 60%, 40% and 
70%) are commonly used percentages for measuring dot gain.

■

The User defined area lets you select individual percentages as 
desired.  For example, selecting 5%, 50%, and 90% would let you 
adjust colors in highlight, mid-tone, and shadow areas.
