Jagged/pixelated Edges between surfaces

Hi, I have a problem that bugs me for years now and I never found a proper solution for: Edges that look fine in Illustrator or exported as JPEGs are jagged/pixelated when exported as SVGs added to a PDF. It´s especially visible where the dark surfaces meet. There is a little room, where the background shows through.

 

My workflow is the following: I draw the outlines and color them with the paint bucket tool. Afterwards I expand and merge same colors with the pathfinder.

 

One option I found is to go go to path - offset path and expand the forms just a tiny little bit. It closes the gabs between the surfaces, but then the other outlines become pixelated, because there are two outlines really close to each other now. It looks better, but still not 100% professional.

 

Thanks in advance.

I can see the anti-aliasing problem.

I also understand why they are not visible in a jpeg export when Art Optimised is used.

I think Offset Path is an option to hide these anti-aliasing problems on screen, but they should not be visible on printers that use PostScript or the PDF Printing Engine.

But I cannot see other outlines become pixelated when Offset Path is used.

In the attachments you can see screenshots of the SVG version with and without the offset path. I have marked one area, where you can see the different smoothness of the outlines. Can you see it?

Yes, I can see it. It improves some areas, so maybe selectively using offset path could help.

Can you please describe step by step what you are exporting where and why this ends up being a JPEG.

 

To get rid of that efficiently, what you could do is of course design this in a way that shapes are actually stacked.

Thanks for your quick reply.

 

I export it as a JPEG under file - export - export as - and select JPG.

 

I could design it that way, but apart from being a very tedious workflow, especially when the illustrations get more detailed, it would also make the paint bucket tool completely unuseable. It separates the shapes automatically, which creates the problem. Why even provide the tool, if you can´t use it?
