Xerox 300x 用户指南

The Profile Curves command is available only in the Expert 
Calibration user mode.  Refer to page 2-9 for instructions on 
selecting this user mode.  

Use the Profile Curves dialog box to set dot gain or dot area at more 
percentage points than in the Dot Gain dialog box.  Start with a base or 
standard printing press profile.  Create a modified profile to match a specific 
printing press, then save the profile for use in the Tektronix driver.   

Use the Profile Curves dialog box to modify the colors in a profile to match a 
particular printing press.  For example:

■

If the colors in a profile, for example SWOP Press, are printing too 
magenta, select Magenta and drag the curve or change the values 
to reduce the amount of magenta.

■

If the mid-tones are too dark in a profile, for example SWOP Press,  
select CMYK and drag the curves down or reduce the values to 
lighten all colors in the middle area.  

You can do one of the following:

■

Modify each primary color separately.

■

Modify the relative lightness/darkness of CMY and CMYK 
without color changes.
