Why does Illustrator add white lines to my pattern when exporting?
I have an object in Illustrator with a chevron pattern that I created in Illustrator. When I export as a
.png file or rasterize image file, it shows horizontal lines.
Anyone have a clue why it does this? I am at a complete loss. It's not the seams of the pattern.
Below is a
.png file export of the image:
My solution was to save as a PDF, open it in photoshop and save it as the raster image. I believe it was poor anti-aliasing as @Scott suggested, which Photoshop handles much better. Art optimized did not improve the issue. It's not an idea solution by any means, but it does work.
Be certain to export with Art Optimized anti-aliasing selected.
Note the hairlines coincide with the dashes on the right. It's a flattening issue which Art Optimized will most likely solve.
If possible, placing a solid, pink-filled shape behind the chevrons would also probably solve the issue by providing the color which Illustrator should use to anti-alias.
This is one of those things with patterns in AI that irks me... poor anti-aliasing.
