I'm using adobe illustrator, and I can't seem to use a stock eps file we purchased. If I remove the illustrated 'glow' elements from their original background, they turn black. What do I need to adjust/change, so that they fade to transparent when I move them to my own files..?
Is there any sort of alpha effect being used in the file?
You could put the elements into a different blending mode such as add or screen and that should remove the black as well.
