overprint effect on photos
i want to layer two photos with 2 different color channels on top with a overprint attribute in indesign, i made sure my fill color were spot colors and i activated my overprint view, it works for shapes but not photographs. and my friend achieved the effect simply by activating overprint in attributes, but i don't know why it is not working for me. please help me out. the first image is my attempt, and the second is my friend's.
