Thin grid lines in PDF export
I am using the current version of Numbers (3.2).
The problem I am facing is that it seems to be impossible to export a spreadsheet with invisible grid lines to a PDF. Every time I do so, thin (I guess 1px) grid lines appear in the PDF where the should be none. I attached two images of a simple test sheet: The first picture is Numbers, the second is the resulting PDF export.
Any ideas how to fix this?
Thanks!
