I've read through a few threads here about white lines in Adobe Illustrator. However, I haven't found any solutions to my particular situation. I created a pattern in Illustrator and there are no visible white lines when I have the file open in the application. Once I export the file to either PNG or JPEG to post to social media, the white lines appear. Does anyone have any helpful hints for this? I'm including a screenshot of my pattern in AI (no visible white lines) and my exported file (visible white lines). Thank you in advance.
When I look at those two I see no visible white lines in either, same when Clicking and seeing full size (1920 x 1200 EIZO monitor).
Are you ensuring whole integer numbers for both sizes and positions?
They're there but only in the oranges in the second image(vertical line). Definitely an anti-aliasing problem but shouldn't show when printing.
Right you are, Larry, one in the middle.
Did you modify the default export settings to use Art Optimized for anti aliasing?
