I'm looking to create a mock up of a book that features an effect similar to the jacket of Stefan Sagmesiter' Made you look. Basically I want to have a 'page' that's a thin sheet of coloured plastic that masks off some red text behind it. When you turn the 'page' and you can see the red text behind the body copy. Kind of like this, but just one page... Anyone got any advice on print methods or techniques to achieve this?
