When I export vectors from Illustrator to transparent PNG and bring that image to Photoshop, the edges become darker especially when vector color is light, like white or light gray. How can I resolve this?
Not sure what your exact export settings are, but one likely reason is the Matte feature, which defines color to blend transparent pixels against. You will see this in the Save for Web dialog box. It has a few options there, what you might need is to set this to None.
No idea, what is the reason. But it's possible in Photoshop to shave your image:
- select the transparent area by using the Magic Wand (tolerance = 0, no anti-alias)
- enlargen the selection 1...2 pixels; Select > Modify > Expand
- press Delete
