CIE optimization bypasses the normal procedure of processing every aspect of
the CIE color space used in applications such as Adobe Acrobat and
Photoshop. This feature increases print speed for documents printed from these
applications by optimizing CIE data. It has no effect on print jobs that do not use
CIE data. CIE optimization should be selected for speed not accuracy, so
printed output may be different from appearance on the screen.
In Imaging > Graphics, select the CIE optimization check box. CIE
optimization is available when KPDL is selected as the PDL.
With Halftone Screen an experienced user can print different shades of gray as
are found in photographs. Shades are produced by printing dots of various sizes
and shapes, and by spacing them closer or farther apart. Shading can also be
adjusted by the number of rows of data, the angle of the rows, and the shape of
the data.
Halftone Screen is available when KPDL is selected as the PDL. It is
unavailable when GDI compatible mode is selected in the Page Description
Language (PDL) dialog box.

Ink
This option is unavailable and is permanently set to Black.
Frequency
Displays the number of rows of dots per inch or centimeter. Set the range from
2.0 to 999.9, and select lines/inch or lines/cm.
Angle
Sets the angle at which rows are aligned. Set the range from -180 to 180
degrees.
Shape
Select the shape of the halftone dot:
Ellipse
Resists optical jump. An optical jump occurs when an area of an image
suddenly become darker. An ellipse shape provides a smooth gradation of
tones. Select Ellipse for images with dark areas.
Round
Resists moiré formation and dot gain. Moiré formation is an unintended pattern
that occurs when two or more colors are printed at the wrong angles. The
correct angles depend on the number of colors being printed. Dot gain is when
the halftone dots increase when printed, causing a moiré pattern. Select Round
for images with light tints and highlighted areas.
Line
Used for special effect. Select Line to change the effect by selecting a different
angle.
