Why do I always find out about these things so late in life ........ ?
Rendering at a higher resolution than your device and downsampling is not a necessary trick. It is also something that you might guess and observe. I would do it with text when my destination printer is an ink jet (some of them hav more than sixteen levels of ink per pixel), and for reasons of compatibility with operator of that ink jet, I am doing the whole page as a 34 megapixel PNG or TIFF. Usually, though, I produce a PDF, so that operators hav nothing to do but run Acrobat; no formatting, colour corrected with -dUseCIEColor (in my GhostScript ps2pdf.bat). At 600 dpi, you just about need to be printing on transparencies, inspecting work with a microscope, or just zooming into actual size (printer pixel==screen pixel) to appreciate such things as anti-aliasing from a downsample.
For perspective, high-quality printed color output (like you see in glossy magazines like National Geographic) is done at 300 lines per inch. -- David gnome@hawaii.rr.com authenticity, honesty, community
