Manual color options
You can manually adjust color options for Edge Control, Halftones, and Neutral Grays.
Edge Control
The Edge Control setting determines how edges are rendered. Edge control has three components:
adaptive halftoning, REt, and trapping. Adaptive halftoning increases the edge sharpness. Trapping
reduces the effect of incorrect color alignment by slightly overlapping the edges of adjacent objects. The
color REt option smoothes the edges.
NOTE If you notice white gaps between objects, or if you notice areas that have a slight shadow
of cyan, magenta, or yellow at the edge, choose an edge-control setting that increases the
trapping level.
Four levels of edge control are available:
● Maximum is the most aggressive trapping setting. Adaptive halftoning and color REt settings are
on.
● Normal is the default trapping setting. Trapping is at a medium level. Adaptive halftoning and color
REt settings are on.
● Light sets trapping at a minimal level. Adaptive halftoning and color REt settings are on.
● Off turns off trapping, adaptive halftoning, and color REt.
Halftone options
Halftone options affect the resolution and clarity of your color output. You can select halftone settings
for text, graphics, and photographs independently. The two halftone options are Smooth and Detail.
● The Smooth option provides better results for large, solid-filled print areas. It also enhances
photographs by smoothing out fine color gradations. Choose this option when uniform and smooth
area fills are top priority.
● The Detail option is useful for text and graphics that require sharp distinctions among lines or
colors, or for images that contain a pattern or a high level of detail. Choose this option when sharp
edges and details are top priority.
NOTE Some applications convert text or graphics to bitmap images. In these cases, setting the
color options for Photographs also affects how text and graphics appear.
Neutral Grays
The Neutral Grays setting determines the method used for creating gray colors that are used in text,
graphics, and photographs.
