Imaging

In the Imaging tab, click Graphics > Halftone Screen.

Clear the Use printer's default screens check box.

Set the available options to the desired values:

Ink

Lists the halftone screens available. For black and white printers, this option

appears 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.

Select Increase accuracy of screens for better print quality, possibly

increasing print time.

Click OK.

Adjusting Grayscale

The grayscale adjustment settings change the Brightness and Contrast of

graphics. These settings are useful if graphic images are printing too light, too

gray, or too dark. Text remains unaffected.

In the Imaging tab, under Adjustment, select Custom.

A preview image in the Adjustment Settings dialog box illustrates any

brightness and contrast changes.

Drag the Brightness slider right to lighten, or left to darken the graphic images

of the print job.
