I had created 24x24 pixels size outline icons (width: 1 pixel) on AI6 and I also used the Path/Outline stroke at the end. When I paste it as shape layer, smart object etc. to Photoshop it looks fuzzy.
The icon located in pixel perfect without any decimal value and I didn't resize it in Photoshop.
What am I missing? could be that there is no way doing that for small icons?
