I am trying to export a map to JPEG. There is always a disruption in one or more of the layers. I made sure that there are no transparent layers except the raster, which is placed at the bottom of the TOC. There are two XY events layers. Usually one of the GeoDB point layers (the biggest in size) is disordered randomly depending on the DPI and JPEG quality chosen by shifting a block of it (not only a few points). I found out that 145 DPI @ 30% JPEG quality fit my purposes.
Is there any practical way of figuring the best DPI and JPEG Quality required instead of trial and false attempts which won???t last as long as the map is progressively modified?
