The rendering styles associated with the PCL driver do not match those 

associated with the PostScript driver.

The Pure Black Text/Graphics option affects the printout for black text and 

 on a page. Under most circumstances, leave this option set to On. When 

Pure Black Text/Graphics is on, black colors generated by applications (for example, 
RGB = 0, 0, 0; CMYK = 0%, 0%, 0%, 100%; or K = 100%) are printed using the 
maximum amount of black toner allowed by the calibration curve. This means the 
black text and line art will not exhibit halftone 

calibrated correctly) and will not be misregistered, since there is only one toner used. 
In addition, this setting eliminates 

.

For some jobs, it is preferable to clear this option, for example, if the page includes 

 fills that use black. The following table describes the behavior of the Pure 

Black Text/Graphics option with black data defined in different color spaces.

Use the Pure Black Text/Graphics option only when printing composites, not 

when printing separations. 

Prints 100% black

With the default profile, prints a rich black using 
all toners.

Prints only with black toner, because CMYK 
simulations preserve the black channel. The actual 
amount of toner used depends on the current 
simulation and the calibration state of the printer.

Prints only with black toner, because spot color 
simulations preserve the black channel. The actual 
amount of toner used depends on the current 
simulation and the calibration state of the printer.
