Halftone Screens
When an image is output to an imagesetter for printing processes or laser printed artwork, etc., the image is converted into a pattern of dots according to well defined Halftone Screen settings. Each Halftone Screen contains a pattern of dots of different sizes or shapes, simulating the effect of different tones and colors.
Ruling Maps
You can predefine screen settings and add them to a Ruling Map. A Ruling Map contains various rules that specify how the screen settings are to be applied. You can re-use a Ruling Map whenever necessary. When creating a job, you can select a specific Ruling Map for processing to avoid any problems due to mistakes.
In the Halftone Screens dialog box, you will see all the available Halftone screens in the upper panel, and all available Ruling Maps in the lower panel. You can use this dialog box to create your own Ruling Maps containing specific halftone screen settings.
NOTE: Any Halftone Screens displayed in italics are not yet licensed, and cannot be used. If you want to license these screens, you must follow the licensing procedure described in the Apogee Licensing Guide.
