I was just working locally on this as a toy project. Assigning. Hi! Sorry for getting back to you so late. Can you send us a sample KRA that I can work with, and the settings you're using for the down conversion and export, respectively?

Created attachment 155297 [details] left- 'Force convert to 8 bit', right - manual merge and convert to 8 bit I've attached a comparison between the two. For some reason, selecting 'Force convert to 8-bit' when exporting as a PNG compresses the image significantly more than manually flattening the image and changing the bit depth to 8 bit.
