Xerox 300x Guia Do Utilizador

Select a curve selection method for adjusting the points on color 
curves: 

■

Select Cyan, Magenta, Yellow, or Black to change the relative 
intensity of individual colors relative to each other.  For example, if 
cyan is printing too dark on the new transfer roll, (resulting in a 
cyanish-black from equal amounts of CMY) you can set the printer 
to print less cyan.  This function works like Gray Balance but 
allows for more fine-tuning.   

■

Select Black or CMY to change the relative intensity of all colors 
together, or the relative intensity of composite black (CMY) to true 
black (K or Black).  

■

Select CMYK to change the density, or relative lightness/darkness, 
of all primary colors proportionally.  This function works like 
Gray Linearity but allows for more fine tuning.

In the Curve Data field, adjust the calibration settings as desired:

■

Click the Restore Default button to return all values to the printer’s 
factory defaults.

■

Drag points on color curves (Cyan, Magenta, Yellow, Black,  CMY, 
or CMYK).  As you drag points on the curves, the numbers in the 
edit boxes change to reflect the selected color curve and the current 
values. 

■

Change the values in the percentage boxes using the increase and 
decrease arrow buttons on the boxes.

Make a test print to check your changes, as desired.  The 
Calibration Curves test print shows sweeps of colors and 
swatches at 5% increments.  Make a print any time to check your 
changes.
