Raster or Vector: To increase the odds of your print looking exactly as it does on screen, you can change the amount of raster (as opposed to vector) in your Design software when exporting to PDF. Note: this will increase the filesize. The reason is that when there are vector elements in the PDF, they must be rasterized before print - thus the term RIP.
