Multichannel mode

This mode uses 256 levels of gray in each channel. Multichannel images are useful for specialized printing.

These guidelines apply to converting images to Multichannel mode:

• Channels in the original image become spot color channels in the converted image.

• When you convert a color image to multichannel, the new grayscale information is based on the color values of the pixels in each channel.

• Converting a CMYK image to multichannel creates cyan, magenta, yellow, and black spot channels.

• Converting an RGB image to multichannel creates cyan, magenta, and yellow spot channels.

• Deleting a channel from an RGB, CMYK, or Lab image automatically converts the image to Multichannel mode. (See "About color channels" on page 93 for more information on channels.)

• To export a multichannel image, save it in Photoshop DCS 2.0 format.
