Manual color options
Use manual color options to adjust the
Neutral Grays
,
Halftone
, and
Edge Control
options for text, graphics,
and photographs.
Setting description
Setting options
Edge Control
The
Edge Control
setting determines the rendering of
edges. Edge control has two components: adaptive
halftoning and trapping. Adaptive halftoning increases
edge sharpness. Trapping reduces the effect of color-
plane misregistration by overlapping the edges of
adjacent objects slightly.
Off
turns off both trapping and adaptive halftoning.
Light
sets trapping at a minimal level. Adaptive halftoning is on.
Normal
sets trapping at a medium level. Adaptive halftoning is on.
Maximum
is the most aggressive trapping setting. Adaptive
halftoning is on.
Halftone
Halftone
options affect color output clarity and
resolution.
Smooth
provides better results for large, solid-filled print areas and
enhances photographs by smoothing color gradations. Select this
option when uniform and smooth area fills are important.
Detail
is useful for text and graphics that require sharp distinctions
among lines or colors, or images that contain a pattern or a high level
of detail. Select this option when sharp edges and small details are
important.
Neutral Grays
The
Neutral Grays
setting determines the method for
creating gray colors used in text, graphics, and
photographs.
Black Only
generates neutral colors (grays and black) by using only
black toner. This guarantees neutral colors without a color cast. This
setting is best for documents and grayscale viewgraphs.
4-Color
generates neutral colors (grays and black) by combining all
four toner colors. This method produces smoother gradients and
transitions to other colors, and it produces the darkest black.
Match colors
The process of matching product output color to a computer screen is quite complex because printers and
computer monitors use different methods of producing color. Monitors
display
colors by light pixels using an
RGB (red, green, blue) color process, but printers
print
colors using a CMYK (cyan, magenta, yellow, and black)
process.
Several factors can influence the ability to match printed colors to those on a monitor. These factors include:
Paper
Printer colorants (inks or toners for example)
Printing process (inkjet, press, or laser technology for example)
Overhead lighting
Personal differences in perception of color
Software programs
Print drivers
Computer operating system
Monitors and monitor settings
