That colour image is indeed a PNG and in my original file compression is turned off. For convenience and size I decided to turn it on for the file posted here.

No bookmarks etc is not an issue at the moment as it first needs to be printed. Publishing online with a pdf that has bookmarks is of later concern.



The windows 10 pdf printer does sound attractive, but I'm using windows 7 and office 2010. I can install windows 10 in a virtual box so I can create a pdf there, but I need to use office 2010 because office 2016 adds a ; to my chemical formulas created with an equation (for example Co2(CO)8 where the 2 must be in subscript and then a 0 must be directly above the 2). Can you install office 2010 in windows 10?

Yes, I have a Win 10/Office 2010 combo on one of my laptops.

Great

The software used to create the black&white drawings (not the color png) allows saving in quite a lot of formats.

Would it be possible to keep them as a vector when using one of the formats that chemdraw supports? Attached is a screenshot.
