I may found the problem or some root causes:
1) Document setup
- rgb/16 -> rgb/8
2) export
- rasterize nothing or unknown only - between these two options are also big differences of course, even the output do not differ that much
- of course jpg quality : hint to affinity devpros: would be nice to have more options here (like imagemagick provides gauss blur, etc.) - set to 70 from 80 half the size of my productfolder
- rgb color palette
remarks:
the option rasterize nothing may cut some layers over layer masks with gradient opacity (e.g. bottom layer is image, top layer a rectangle with opacity gradient fill ) ... of course I may change the overlay of image, but this would mean to change the whole document (87 pages) with a lot of grouped layers to come to the same effect
