Whenever I export a shape or vector with a transparent background (as a PNG)—I get a strange faint border around the image after export. If I place the image back into illustrator, the border shows, and when I zoom in, it disappears.
(In the image, I have placed the exported IMG on top of the pre-image to show that border)
Are there any solutions to this issue?
Try if selecting Art Optimized for Anti-aliasing in the PNG Options helps.
That still didn't work, but it did make the faint outline black—and that's still not what I'm looking for. (The image is what it does with the "Art Optimized.") I am saving it as 300PPI with a transparent background. I've explored many posts, possibly regarding this issue, but I haven't found a solution yet. Are there any other solutions?
Can you share an Illustrator example, so we can have a look at it?
Are you suggesting that I share the file with you? I have the .ai file, but I'm unsure of how to upload/send it to you.
Sometimes it is got to do with the system as well...
Can you please share the file .ai to see if it happens on other system as well....
Yes, if you could share the .ai file (or the problematic part of it) using CC files sharing, Dropbox, WeTransfer, Google...
May I ask for your email, so I can send the file over to you?
I cannot detect something special with your file, but I can see the faint line in GPU Preview.
GPU preview is fast, but does not give you the best quality.
When switching from GPU to CPU Preview the faint lines disappear.
Thank you for your suggestion—but when I export as a PNG, I'm still seeing a faint line around my shape. I even turned off GPU completely in the performance settings, and I'm still finding the faint line.
As as I can see it is a display problem in Illustrator.
Zooming let it disappear and with Cmd E (switching to CPU Preview) it also disappears on my machine.
I checked the png in Photoshop with a background layer of the same color and no lines were visible.
I brought up this topic because while I was exporting these PNGs from Illustrator into a 3d platform, implementing these PNGs as UI, I saw the strange borders. And this is on a platform other than Illustrator, leading me to believe that it isn't just an Illustrator display problem.
Were you able to fix this? I had the same problem at work today when saving a png, couldn't fix it.
