Toshiba GA-1121 User Manual

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 

 (as long as the copier/printer is 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. 

PostScript applications (such as QuarkXPress) may convert elements defined as 

RGB = 0, 0, 0 to four-color CMYK black before sending the job to the GA-1121. 
These elements are not affected by the Pure Black Text/Graphics option. For details, 

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 
copier/printer.
