"""I assume you know that you can render to disk at even larger sizes, then use a graphic editor like IrfanView to resize/resample down to half the original, so as to get a form of anti-aliasing applied to your image. It makes the edges even smoother, and usually ends up adding additional colors from the basic 256 (8 BitsPerPixel) mode to the 16.7 million (24 BitsPerPixel) mode."""
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. In the usual scheme of things, to save myself time and trouble, I render at seventeen megapixels and resample for the screen: 672by900 works out to a full page, according to Internut Explorer concerning background images, just over half a megapixel. Seventeen megapixels is a nice size of starting resolution for laser printing fractals that are ten inches square at Office Depot or Staples; 300 dpi. is nine megapixels at that size. 1400by1400 (times 3by3 in batch files)==4200 pixels square (17 megapixels) is a size in fractint.cfg that I orijinally wrote for the Fractal Universe Calendar contest, which is down. Their payout, US$400, was far short of royalities, though. So, getting into that calendar was about becoming known. I am probably better off making a connection with a marketing house in Edmonton -- i.e. formatting a calendar, myself, and getting someone to promote it under the banner of someone's business, OR doing the whole job of getting a sponsor, myself, and using the marketing house pretty much as a print shop for calendars. Offset presses typically still run at 300dpi and four colours per pixel, because it is hard to tune four colour-separation presses more precisely than that. Sales is not my strength.
