I am transitioning from Corel and beginning to design in Illustrator and Photoshop. My images/designs are very clear in the programs but when I export into a png file, they become pixelated, despite proper settings for high resolution. I never had this issue in Corel. I must simply be doing something incorrectly when exporting. I'd greatly appreciate someone's expertise and insight on this. Thanks.
We can't know. You have not provided any exact system info, document info, export settings and so on.
I am using Illustrator and Photoshop CC. When exporting from illustrator, I'm selecting a png file with a high resolution of 300 ppi. Anti-aliasing, type optimized (hinted). Background: transparent.
