Thanks, Hans. I have never used transparency in PNG, and often it’s more 
practical to avoid the detour of Powerpoint-type software and just show 
pdfs… hence my request.

The 2.25 property-defaults method unfortunately doesn’t affect markup 
outside of scores. Harm’s method from the other sub-thread seems to 
partly do…

I suppose I might make a feature request for a background-color paper 
variable.

Best, Simon
