  • Inverted Clipping Mask / Knockout Mask…

    Posted by Eric Barker on June 5, 2009 at 10:29 pm

    I’ve never had much use for clipping masks, it just seems much easier to create a layer mask, or if at all possible, a vector mask, instead. However, one thing I’ve always wondered is if there was any way to do a inverted clipping mask, or a “knockout mask”. I often need to have something like a rectangle of pixels with text in them knocked out (alpha’ed). Using just two layers: a shape layer and a text layer, is there any way of accomplishing this? In the past I’ve simply converted the text into a shape, and then used that to create a vector mask for the shape layer. But this can get combersomb after a while, is there anything more efficient?

    In case anyone, like me, stumbles upon this because they have the same question. I just found the answer:

  • Place text above rectangle
  • Open Blending Options of text (by double clicking the layer or right click->blending options)
  • Under Advanced Blending you’ll find the “Knockout” option:
  • Set that to shallow (to knockout just the layer below)
  • or deep (to knockout everything until it reveals the background layer)
  • Reduce the fill opacity to 0%
  • done! Hope that can help someone 🙂
