On-screen these images appear slightly blurred or indistinct. However there is a marked improvement in the print quality. The ``anti-aliasing'' helps on-screen; in the printed version jagged edges are indeed softened but leaving an overall fuzziness.
the same equations yet again; this time with `extrascale=2.0'.
Now there are 4 times the pixels at a cost of roughly 2.45 times the disk space.
Compared with the previous images (having 1.5 times extra-scaling),
there is little difference in the on-screen images.
Printing at 300dpi shows only a marginal improvement;
but at 600dpi the results are most satisfying, especially when
scaled to be comparable with normal 10pt type.
