This question was marked as a duplicate: This question already has an answer here: \includegraphics PDF, color problem but I don't see that it is. I had previously looked at that question, and even tried some of the suggested remedies. But my issue is not with the display (which seems to be the subject of that question) but with the printing. Perhaps I am missing something about the way in which pdf graphics are handled.
Original message:
I am writing a document that has a number of images produced via Inkscape (0.91) and included in my latex document (I'm using TeXshop on a Mac OS 11.5) as pdf files via \includegraphics. These render just fine on screen, but don't print well using various printers; you can see the issue already from printing to a pdf file.
The issue is that regions that have shading or blurring (two effects you can produce in Inkscape) don't print at all. At the bottom is an example; you can find the graphics file at http://people.brandeis.edu/~ruberman/concordance2.pdf. If you want to see the native Inkscape .svg version, it's there too: http://people.brandeis.edu/~ruberman/concordance2.svg
Any suggestions on how to handle this? Thanks!
