Grayscale
Use the Grayscale options to adjust the appearance of graphics and text produced.
Grayscale adjustment settings let you change the Brightness and Contrast of
graphics. Grayscale adjustment settings are useful if graphic images are printing too
light, too gray, or too dark. Text remains unaffected.
1 Click Adjustment to open the Adjustment Settings dialog box. 1
A preview image in the dialog box illustrates any brightness and contrast changes.
2 Drag the Brightness slider right to lighten, or left to darken the graphic images of the
print job.

You can also change brightness by entering a numeric value in the text box at the
right. The brightest setting is +100; the darkest is -100. Zero is the default mid-level
setting. Adjusting brightness is useful when graphic images are printing too dark or
too light. Text remains unaffected.
3 Drag the Contrast slider right or left to increase or decrease proportion of light to
dark in the graphic images of the print job.

A high contrast setting decreases the grayscale spectrum, making light grays lighter
and dark grays darker. A low contrast setting increases the grayscale spectrum,
making light grays darker and dark grays lighter.
You can also change contrast by entering a numeric value in the text box at the right.
The highest contrast setting is +100; the lowest is -100. Zero is the default mid-level
setting. Adjusting contrast is useful if graphic images are printing too gray, or too
black and white. Text remains unaffected.
Shape Select the shape of the halftone dot. The choice for the
best halftone shape depends on the pattern and
number of colors for your image.
Ellipse Resists optical jump, which is when areas of
an image that should be smooth suddenly become
darker. An ellipse shape provides a smoother
gradation of tones. Choose 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.
Choose for images with light tints and highlighted
areas.
Line Used for special effect. You can change the
effect by selecting a different Angle.
Increase accuracy of
screens Uses a very precise halftone screen which provides
better print quality, but may increase printing time.
