Hi Laubender​, I copied, via clipboard, just the graphic from Illustrator to InDesign and exported to PDF. I had the same issue. The graphic has 3 colours, each with a gradient (dark-light-dark), as if the colour emanates from the middle (light) and gets darker toward the edges of the design. Maybe it is just something wrong with the way I created the graphic in Illustrator. Cheers, Ken
