A table shows all currently defined spot colors. The columns provide the following information:
- V (Visible): If you click the eye icon in this column you can hide or display a spot color.
- No. (Number): Enter here a number for the spot color.
- Name: Enter here a name for the spot color.
- Halftone Frequency: This column determines how fine the typesetter will present halftone screens. The standard value is 150 lines per inch (lpi). Read more about this topic in the Wikipedia Article.
- Halftone Angle: This determines the angle of halftone screens. The standard value is 45°. Read more about this topic in the Wikipedia Article.
If dotted areas are rendered as a halftone screen, then the halftone 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 AI and PDF format with spot colors.
