I am relatively new to Illustrator. I use version CS6 and I just discovered that when I apply an outer glow effect it is not visible in the PDF after saving apart from when you make the effect really strong. I am currently writing my thesis using latex and when I include the PDF in my latex document no outer glow effect is visible at all. Has anyone discovered a similar behaviour?
It was really just the PDF viewer I used. In my case, it was Preview from Apple.
Adobe Reader, the glowing effect was visible.
