I'm a little late to the party, however, I hope this helps @klevteev or somebody else...

Code: Select all

// CMYK mode file: remove all channels except for the composite channel
if (documents.length > 0) {
    if (activeDocument.mode == DocumentMode.CMYK) {
        try {
            for (var i = activeDocument.channels.length - 1; i >= 0; i--) {
                if (activeDocument.channels[i].kind != ChannelType.COMPONENT) {
                    activeDocument.channels[i].remove();
                }
            }
        } catch (e) {}
    }
} else {
    alert("There must be at least one open document to run this script!");
}
