I've often wondered how a combo of RGB values would correspond to an individual ink channel and if it was even possible to linearize each channel given that there's somewhat of a translation layer sitting in between. Unless you're using a RIP that has access to individual channels, any patches you generate with the intent of targeting a specific channel are just a guess and probably won't actually isolate that channel.
