What's up, all? I posted another video tutorial today showing how to swap out channels in your separations. The method, although shown using a simple spot color separation file, can be used on any form of separations from spot to index to simulated process.
You may find it useful to utilize this method if you've already output the film and want to change a few or have a press waiting to get an updated screen. Here's the link.
