Problem: exporting png or jpg gives me not aliasing

You have to first switch to RGB color space and then the anti-alias works.

Problem solved!

I started another design and didn't face the same problem. So I figured that something in that 1st file is causing this. First I checked all photos and elements deleting them one be one... and finally got to one png file (was outside of my canvas and it took a while to find it (narrowing files from links) and by removing it, everything got better. I did flatten png in PS and saved it and vola! - suddenly everything works with that png.

Hi there,

Sorry to hear about the trouble. Could you please share a few more details like:

• OS & version of InDesign
• Is the issue related to a specific document or all? Are you able to replicate this in a new document?
• Could you please share the document with us? You can upload it to the Creative Cloud (https://helpx.adobe.com/in/creative-cloud/help/share.html) and share the download link.
• Are there any recent changes made to your system? For example, any antivirus, system updates, plugins, or web extensions installed recently.
• Does resetting InDesign Preferences (https://helpx.adobe.com/indesign/kb/indesign-preferences-support-file-locations.html) help to resolve the issue?
  Disclaimer: Please note that resetting preferences will remove all the custom settings, and InDesign will launch with default settings. You can also take a backup of the folders in case you want to. Location is mentioned in the article.

We will be looking forward to your response.

Well, you may have discovered a new bug with InDesign.

Could you provide a sample document?

Put it on Dropbox or a similar service and share the download link.

Plus a screenshot of the export preferences for PNG and/or JPEG.

And: Do you export a selected element or a page?

( Could make a difference as well. )

Thanks,

The easiest way to fix this:
Export to PDF, open the PDF in PhotoShop and export from that to PNG.

You may use the legacy export for web feature with previewing the output.
