I've plotted some data (in R for those that are interested), and exported my plot to PDF to make some final edits to the figure. When I open the original exported PDF in adobe reader, the file displays properly
I thought this was just a display problem, so made my edits etc. however when I export the final edited figure back to PDF it looks just like it did in illustrator.
I've had illustrator do something similar before
but when I exported that plot it comes out the correct way, which is why I thought it might just be a display problem
I really need the image to have the smooth interpolation between the colours as it was in the original exported PDF. How can I make illustrator keep this information?
