Having upgraded to SU 2018 running MacOS High Sierra I’m having trouble with some pages in Layout not printing full colour. It’s usually the first page that is fully or partly pastel. The rest of the pages are print fine even if it is the identical drawing. This wasn’t happening when I first upgraded but now is a permanent bug.
It seems that I no longer have the direct function to print directly to a PDF without this happening. Sometimes I can get around it by exporting the drawing and playing around with the export options but this does not always work. Other times I shut down and on restart it will export full colour on all pages.
