Neutral Grays
The Neutral Grays drop-down menu controls the selection of a device-dependent color table that is
embedded in the product firmware. You can adjust the Neutral Grays setting independently for text,
graphics, or photographs. The following options are available:
●
Black Only. This option generates neutral colors (grays and black) by using only black toner.
This option guarantees that neutral colors do not have a color cast. Black Only is the default
setting for the Text and Graphics components.
●
4-Color. This option generates neutral colors by combining all four colors of toner, which
produces smoother gradients and transitions to non-neutral colors. It also produces the darkest
possible black. 4-Color is the default setting for Photographs.
Color Themes
The Color Themes group box contains the following RGB color options, which determine how colors
are rendered:
●
Default (sRGB)
●
Photo (sRGB)
●
Photo (Adobe RGB 1998)
●
Vivid (sRGB)
●
None
Default (sRGB)
NOTE: To activate the Color Themes controls, clear the HP EasyColor check box.
Select Default (sRGB) for most printing needs. This setting instructs the product to interpret RGB
color as sRGB, which is the accepted standard of Microsoft and the World Wide Web Consortium
(W3C). Colors are matched to optimize the RGB colors on the screen and to provide vivid images
and graphics.
