Mapping Pen Colors
You can create design-color to print-color, output-transparency, output-grayscale, output-screening, and output-width mappings, via the Pen Table - Map Design Colors to Output Pen Symbology dialog. This dialog opens when you click the Map Pen Colors button in the Global Actions section of the Modify Pen Table dialog. This mapping method is implemented in the same manner as the color maps in the printer driver configuration file, and can be considered a user interface for that feature. This approach lets you create color and width resymbolization on a per-stroke basis. This is the only way some results can be achieved, such as screening multi-colored associative patterns and custom line styles.
The pen map list box consists of the following columns:
- Design Color — Only color indices 0 through 254 may be mapped. Output symbology cannot be assigned to the background color (index 255).
- Enabled — Individual pen maps may be disabled if desired. This preserves the settings in the pen table file, but prevents them from affecting the print. The Enabled column may be useful if you want to use both pen table pen maps and .pltcfg files' color maps. Unless disabled, pen table pen maps override those in the .pltcfg file.
- Print Color — Optional specification of print color using the RGB color model.
- Transparency — Optional transparency value, with a range of 0 to 100. 100 indicates fully transparent, 1 indicates opaque, and 0 indicates no transparency values should be defined in pen mapping.
- Grayscale — If checked, the print color is converted to grayscale.
- Screening — Optional screening factor, with a range of 1 to 99. This control is used to "wash out" a color towards white in the printed output. A 50% screen, for example, moves a color halfway to white. Screening can be used to save ink, or to de-emphasize elements plotted in that color. A screening value of 100 means do nothing.
- Width — Optional print width in either millimeters or inches.
