Halftone Screen
Option
Description
Ink
Color used in the printed output. For Monochrome
models,
Black
is the only available ink color.
Frequency
Number of rows of dots per inch or centimeter. Enter a
numeric value in the
Frequency
text box, and select
lines/inch
or
lines/cm
.
Angle
Select the angle at which rows are aligned. An angle is
measured in degrees, ranging from -180 to +180.
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.
Grayscale
Option
Description
Print text as black
Prints all color text as black. This is useful when you
want to reduce the amount of data sent to the printer
for color print jobs, which can provide faster printing. It
is also useful for increasing the detail for light colored
text printed by monochrome printers. White text and
image colors are unaffected.
