When Grayscale is On the object’s colors are converted to gray scale if your plotter supports gray scale. colors are mapped to the nearest color (which can limit the range of colors used for plotting) if you turn off dithering. you can turn off dithering to avoid false line typing from dithering of thin vectors and to make dim colors more visible. this can give the impression of plotting with more colors than the ink available in your plotter (if your plotter supports dithering). You can Enable Dithering to approximate colors using dot patterns. you can scroll to select the first 7 ACI colors directly or pick Other to select an ACI color from the complete color palette. this is how you can create a monochrome plot style (override the object color by selecting Black as the plot color).

or you can assign a specific plot style color to override the object’s color at plot time. You can Use object color for the plot style color so objects will plot using the same color in plots as they appear on your screen. the remainder of this section briefly describes the various editing options in the plot style table editor. the primary difference between stb and ctb plot style table files is how objects are mapped to plot styles. You can edit stb & ctb files using the same methods – this is practical for editing named plot style table files. You can change properties of specific plot styles (without having to select the desired style first) in the Table View. Use the Form View when you want more than one plot style to have the same setting(s) (practical for color dependent styles). The plot style table editor can be viewed in two different formats. – you can only edit table file types (ctb or stb) that the active drawing was set up to use if you pick Edit on Page Setup. You can also pick the Edit button in the Page Setup dialogue box to edit the plot style table file attached to the current page setup.

double-click on the desired table file icon to open a plot style table file for editing.

or use Add-A-Plot Style Table Wizard to create new table files.

You can edit these supplied table files and save them with a new name to create new customized table files

for example, the acad.ctb plot style table file plots objects (if possible) the way they appear on-screen.

named plot styles are also saved in plot style table files but these tables use an “stb” file name extension.ĪutoCAD is supplied with several plot style table files.

objects can then have a plot style as an object property just like objects can have color and linetype properties.

When you Use named plot styles you can assign specific styles to each object explicitly and you can assign styles Bylayer.

color dependent plot styles are saved in plot style table files with a “ctb” file name extension.

you should use this approach if you plan to use the monochrome plot style table for monochrome output devices.

this approach is similar to plotting in earlier AutoCAD releases and it is probably the easiest method to understand and use.

When you Use color dependent plot styles you map each object to a specific plot style according to the object’s color on-screen.

if you create new drawings from a template (or use Saveas) the new drawing will use the same plot style behavior.

once you make a new drawing it will use either color dependent plot styles or named plot styles and you cannot change this.

you must select the plot style behavior that you prefer BEFORE you create a new drawing.

There are two different ways to use plot styles. You must first attach a plot style table to a layout with the Page Setup before you can use plot styles when you Plot.

technical drawings used to make blueprints should normally be created using monochrome plot styles.

objects retain their color on-screen but are sent to the output device as if they were black (white on black backgrounds).

for example, lines may be faint or seem “pixilated”. One way to improve output on monochrome devices is to use a monochrome plot style that substitutes black ink for all screen colors.

if you try to send color output to these monochrome devices your plots may not be of optimum quality.

laser printers) produce output using only black ink or toner (i.e.

you may want to change some object properties at Plot time (only) and this is what plot styles were designed for.

if your plotter can output objects as they appear on-screen (and if this is what you want) then plot styles are not required.

You do not have to use plot styles in AutoCAD.
