    Semi-transparent block, pure black and rich black problems

    Psychophage

      Hi!

      I'm new to inDesign, and I'm currently designing a book cover, for which I need some special effects. I'll try to explain as best as I can.

      The background is rich black, on top of it I have a text in white (all over it). I applied a block with 80% opacity, in rich black color. I cut out some shapes in it. The point was to have the text in dark gray all over the book cover, but in white in the places where I have the shapes.

      Everything is working exactly like I want, but a friend of mine told me if I apply rich black over white, I'll get a kind of magenta gray, so I have to apply pure 100 K to avoid that and get the dark gray I want. I tried that, and of course, applying some pure black block on top of my rich black cover gives all the cover a "grayish black" look. How can I work around that? I tried setting my semi-transparent block to "darken", but it didn't change anything.

      I put the links to the pdf, I hope that's ok.

      That's the one with rich black: https://dl.dropboxusercontent.com/u/68049919/coverlayout_print_richblack.pdf

      and that's how it looks with the pure black: https://dl.dropboxusercontent.com/u/68049919/coverlayout_print.pdf

       

      Thanks a lot!
