RGB PURE BLACK

PURE BLACK TEXT

SETUP Menu Settings
ON*, OFF
Enables you to specify how black and gray data with the equivalent ratio of R to G
to B should be processed when device dependent RGB data is converted into
device dependent CMYK data using "RGB Source Profile" of the printer.
If ON is specified, black and gray data with the equivalent ratio of R to G to B is
printed using the black (Bk) toner only, regardless of the selected setting for
OUTPUT PROFILE.
If OFF is specified, black and gray data with the equivalent ratio of R to G to B is
printed according to the selected setting for OUTPUT PROFILE.
IMPORTANT
If black or gray data is printed, and if unsmoothed gradation or graininess appears
on the printout results, specify OFF for this item and set OUTPUT PROFILE (See
p. 5-97) to NORMAL.
NOTE
In combination with certain settings, black and gray data with the equivalent ratio of
R to G to B may be printed using the black (Bk) toner only, even if OFF is specified
for this item.
The following are examples.
- When PURE BLACK TEXT (See p. 5-98) is set to ON
- When RGB SRCE PROF. (See p. 5-95) is set to NONE
- When OUTPUT PROFILE (See p. 5-97) is set to TR Normal or TR Photo
If OUTPUT PROFILE (See p. 5-97) is set to NONE, the setting for this item is
ignored.
ON*, OFF
Specifies the printing method for text in black (R=G=B=0%, C=M=Y=100%/
Bk=N%, or C=M=Y=0%/Bk=100%). Usually, it is recommended to leave this item
set to ON.
If ON is specified, you can print black color created by an application, using only
the black (Bk) toner. Since only the black (Bk) toner is used to print black text, the
color (CMY) toner will not be misaligned around the text.
