Define Spot Colors

ToDo

• Visible: Check this option to display the spot color.
• No. (Number): Enter here a number for the spot color.
• Name: Enter here a name for the spot color.
• Halftone Frequency: This determines how fine the typesetter will present half-tone screens. The standard value is 150 lines per inch.
• Halftone Angle: This determines the angle of half-tone screens. The standard value is 45°.

If dotted areas are rendered as a half-tone screen, then the half-tone screen angle should be different from the angle of the dots to avoid Moiré effects on the printed map.

• Appearance: These values are used for the spot color view (the spot color view is a simulation of the map printed with spot colors). They are also used when exporting the map in the Adobe Illustrator format with spot colors.
