You can use a plot style
to assign color, screening, grayscale, and dither properties.
Assign Plot Style Colors
The default setting for plot style color is Use
Object Color. With this setting, the object retains its layer or
individually set color. If you assign a plot style color, the color
overrides the object's color at plot time. You can specify one of
255 ACI colors, a true color, or a color book color. The plotter
must be configured for True Color if you want to plot True Color
plot styles.
NoteIf you use a plot
style table saved in AutoCAD 2000 or later, the True Color values
change to the nearest match in the current version's palette.
Use Screening
You
can select a color intensity setting that determines the amount
of ink placed on the paper while plotting. The valid range is 0
through 100. Selecting 0 reduces the color to white. Selecting 100
displays the color at its full intensity. Screening is effective
only if your plotter is configured to plot colors or grayscale.
Also, dithering must be enabled.
Use Dithering
A
plotter uses dithering to approximate colors with dot patterns,
giving the impression of plotting with more colors than the ink
colors available in the plotter. If the plotter does not support
dithering, the dithering setting is ignored.
The most common reason for turning off dithering
is to avoid false line typing from dithering of thin vectors and
to make dim colors more visible. When you turn off dithering, colors
are mapped to the nearest color, which limits the range of colors
used for plotting. Dithering is available whether you use the object's
color or assign a plot style color.
NoteDithering disables
merge control.
Convert to Grayscale
When
you select Convert to Grayscale, the object's colors are converted
to grayscale if the plotter supports grayscale. Light colors, such
as yellow, are plotted with light gray values. Dark colors are plotted
with dark gray values. If you clear Convert to Grayscale, the RGB
values are used for the object's colors. Conversion to grayscale
is available whether you use the object's color or assign a plot
style color.
To assign a plot style
color
- Right-click a CTB or STB file. Click
Open.
- In the Plot Style Table Editor, Table
View tab, click the Color field for the plot style you want to change.
- On the Color drop-down list, click the
color you want to use or click Select Color to display the Select
Color dialog box and do one of the following:
- On the Index tab, click a color or enter
the ACI color number (1-255) or name in the Color box. Click OK.
- On the True Color tab, in the Color Model
box, specify a color. (Enter a color value in the Color box or specify
values in the Hue, Saturation, and Luminance boxes.) Click OK.
- On the Color Books tab, in the Color
Book box, select a color (use the up and down arrow and click on
a color chip.) Click OK.
To use screening
- Double-click the plot style table that
you want to modify.
- In the Plot Style Table Editor, Form
View tab, select the plot style you want to change.
- In the Screening box, enter an intensity
value between 1 and 100.
- When finished, click Save & Close.
You can edit properties for multiple plot styles
while in the Plot Style Table Editor.
NoteA common practice
when using screening is to set the plotted color to black for each
style so that the screening will be a percentage of black.
To enable or disable dithering
- Double-click the plot style table that
you want to modify.
- In the Plot Style Table Editor, Form
View tab, select the plot style you want to change and select Dither.
- Select On or Off.
- When finished, click Save & Close.

To enable or disable conversion
to grayscale
- Double-click the plot style table that
you want to modify.
- In the Plot Style Table Editor, Form
View tab, select the plot style you want to change and select Grayscale.
- Select On or Off.
- When finished, click Save & Close.
