 |
|
Hello, I need help making this into a 2 color image without having the pink sink through the photographs on back. When I delete the cyan and yellow it ruins the pictures on the backside. I could really use some help on this, we need to get it to press soon.

Maybe try using 'select > colour range', selecting the background pink colour with a sharp threshold, and then inverting the selection. Creating a non pure pink selection, which can then be deleted from the magenta channel.

Thanks so much for the advice, I have been trying to do that and I am a bit confused. What do you mean by selecting the background pink colour with a sharp threshold? I guess I don't know as much about this as I thought. Could you walk me through it maybe?

Ok I had a think about it... If your image hasnt been flattened or anything what about pasting the pixels from the separate layers into the channels to which they belong. Would still have to crop the pink background but would solve the bad selection edges problem.
