Using spot color channels
Spot color channels let you view, edit, and preserve spot color information in files. Whether you are importing a file that uses spot colors or you add spot colors in Corel PHOTO-PAINT, spot color channels ensure that your color information is maintained when you output the file. The spot color is stored in an 8-bit grayscale channel that preserves information such as which spot color to use, where to apply the ink, and at what density.
You can create a new spot color channel, assign a color and name to the channel, and then add content. For example, you can paint, draw shapes, apply effects, or paste content onto the channel. When you paste an object or selection to a spot color channel, it is added as an editable area. You can modify the editable area before you commit it to the spot color channel. For more information about modifying editable areas, see “Working with masks.”
When you preview your image, you can choose whether spot colors mix with underlying colors (overprint) or cover underlying colors. This can be used to simulate opaque or transparent inks.
You can also select, edit, and change the properties of existing spot color channels. For example, if you open or import an image that contains spot color channels, you can edit channel content, rename a channel, or change the spot color of a channel. When you view images, you can choose to hide or display the contents of spot color channels or change the order of the channels. You can copy spot color channels between images and you can delete spot color channels when you no longer need them.
Whether you are creating a new channel or editing an existing one, you can add or erase channel content by changing the color for the tool you are using. For example, painting with black applies a solid color, painting with white erases the color, and painting with gray applies a tint of the color.
You can save your work to the CPT file format if you will be doing further editing. You can also save to the PSD file format or export to the DCS, PDF, or EPS file format if you are ready to print.
