Hi - is it possible to create a gradient transition over another? I created a master slide (right page of a spread) with a background that trasitions from dark grey to light grey. I want to add another gradient on top of it, positioned in between the two pages of the spread, to give the illusion of a book spine/shadow. . .but it looks funny because the "shadow" doesn't blend in with the main page gradient. Any ideas?
Set the transparency mode for the top gradient to Multiply in the Effects panel. If you want this on every page put it on the Master Page on its own layer and make that the topmost layer. Lock the layer to prevent accidentally drawing anything over it. If this is for print you might want to make a Text layer above this gradient layer and put all your text on that layer.
