I'd be game for some instruction. It looks like your overall method is pretty much what I'm used to, though much more refined. I noticed you doing some things with channel options I think that are alien to me, but I lack basic instruction on using PS features from a color separators point of view.
If other printers are like myself, they're focused on color interaction on-press when separating and working against the clock so to hell with taking time to learn more about how to use PS, I'll just keep floundering around until I get what I want. I know it's a bad m.o. but get annoyed reading tutorials on these basics that are geared toward other industries. It'd be nice to learn while keeping your 'eyes on the prize' so to speak. Make that tut vid and I'll buy one.
