thin white lines in illustrator export (or import illustrator artwork into photoshop)

[hemag nova grafik]

hi guys

when i export an artwork in illustrator (export for screens) i get very thin white lines in the artwork.

 

the same lines appear when i copy paste the art from illu to photoshop.

 i guess it has something to do with resolution and pixels but i cannot fix it. i know i can place same-colored backgrounds but i want to avoid this unnecessary work and also, the lines would probably persist between the different backgrounds. that would work if your art has only one color but not if there are many different colors. 

the only way so far is to convert the art in illustrator to an pixel-image and then copy it to photoshop. but this solution is also not satisfactory.

Those are anti-aliasing issues.

Are the artboards and the artwork aligned to the pixel grid exactly?

And you do not resample when exporting?

thanks for your answer. well no, the artwork is not perfectly alignet to pixel grid.
when its perfectly alignet then the issue is not visible in illustrator:

 

but it is still visible in photoshop:

the issue is still visible in illustrator and photoshop when i use non-pixel-perfect shapes such as for example this triangles. then i still see some of the lines. not all but some of them.

sorry for the bad screenshots they barley show the issue

[hemag nova grafik]

ah now they do 🙂 nevermind the screenshots are ok

Unfortunately this is how antialiasing works. What are you planning to do with them in Photoshop? Antialiasing is not needed for them, so how about turning it off for scaling?

how can i turn it off for illustrator export and how do i turn it off when copy something from illustrator to photoshop? i use it a lot for copying stuff from ai to psd, but mostly single-colored things where this issue does not exist.

When you export, do you use Art Optimized Anti-aliasing?

You can also apply a non destructive Rasterize Effect in Illustrator with anti-aliasing turned off before copy-paste into Photoshop.

well that is the topic of this thread - how do you do that? 🙂 i don't because i never head about this function

[Ton Frederiks]

In the export for screens window, you see a little cogwheel that you can click to change the settings.

thank you, i did not know about this settting, its also barley small 🙂 well it works for png but not for jpg. and the problem still persists when i copy stuff from ai to psd. i guess there is no solution for that? i find it quiet strange that in 2024 we are not able to copy art from ai to psd without loss of qualit, is it really like that? 🙂

[hemag nova grafik]

ps: what kind of non-destructive rasterize effect are you talking about?

[hemag nova grafik]

ah i found it, its called ,convert to pixel image' in german, and that works fine also when copy stuff to photoshop. well thanks a lot, thats what i was looking for! have a nice day

Good to hear that helped!

Here is a description on how to use the raster effect as a graphic style:
