Okay, I'll be the first to admit that I know far too little about CMYK aside from processes. But at any rate, what's happening is that I'm going to need to send a few files to a printer and the guy paying the bill can only afford two colours. In this specific instance, black and yellow.
Does anyone know what the best way is to get Photoshop to ditch the magenta and cyan channels so I don't get any of those colours in the image at all? Basically it's a black and white image which we'd either like to retain a bit of continuous tone yellow, or to burn on a yellow over the existing black and white areas. Or can I literally just ditch the cyan and magenta channels? (in which case, should I start with the greyscale file or the colour file? Assuming I want preferably be able to do greyscale conversion from full colour data rather than just the yellow channel/black channels).
Many thanks for any help.
