Join Mordy Golding for an in-depth discussion in this video Using the Knockout Group setting, part of Illustrator: Seeing Through Transparency.
Okay, so now we understand exactly what a knockout is inside of Illustrator.…Again, it's a default behavior whenever you're dealing with overlapping objects…with different colors, where the top object knocks out or removes the actual…part of the object that exists directly beneath it.…That prevents colors from mixing on press, giving us unwanted color changes.…However, in the world of transparency, the whole concept of knockout is…completely different.…Because if you think about it, if I take let's say just this shape right here…and I'm working on this file here called flower2.ai, and I select this element…right here and I choose to actually make it transparent by maybe applying an…Opacity of 50%, so now I'm telling that object to only be 50% in opacity.…
What does that mean?…That means I won't be able to see through that object and obviously I…want to see through it to see what appears beneath it.…I mean that's the whole point of transparency--…the ability to actually see through an object and to see what's behind it.…
