The Swatches panel provides color swatch presets that are selectable from various categories. You can easily apply grays, solid colors, or gradient colors as presets.
To use a color swatch:
Accessing PANTONE® Colors
PANTONE® Color palettes are available from the main Swatches panel, and will automatically become a global spot color in the document palette when applied. They are also available from the pop-up Swatches panel on the context toolbar when a shape, line, or stroke is selected.
To access PANTONE® Colors:
On the Swatches panel (or pop-up Swatches panel), from the category pop-up menu, select your preferred PANTONE palette.
To display the PANTONE® Color name and number, select the Swatches panel's Panel Preferences menu and choose Show as List.
Registration color
Printing to PDF will allow you to include printer marks, including registration marks assigned with registration black (100%C:100%M:100%Y:100%K). Registration black will appear on any PANTONE or additional spot colors added. You can add this registration color as a swatch that can be assigned to an object on the page, creating an on-page registration mark.
To add a registration color as a swatch:
From the Swatches panel, click Panel Preferences, then select Add Registration Color.
You can then apply the swatch to an object on the page.
