216 * 279 mm ?

Hello,

no, that is wrong. Only if the ration between the short and the long
side is sqrt(2) you may cut two halfs of one sheet with the same ratio
of the sides. Our DIN A4 ist 210 * 297 mm, DIN EN ISO 216.

Hi Nico,



I think, nowadays, its relatively easy to get 300 dpi. 600 dpi
will quickly replace that. I never need to turn on 1200 dpi to
get a quality drawing -- even on A size paper.

Inkjet printers are probably *not* a good idea for schematics
as they tend to have larger dot sizes. IMO, inkjet only makes
sense for really low power and/or "color" (neither of which
seem to be necessary -- IMO -- for producing schematics).

I think pen plotters were in the 0.3mm region for line widths
(rapidograph tip). If so, figure ~100 per inch (ignoring ink
bleed). So, every three inches of plotter dimension corresponds
to an inch of 300dpi printer dimension. I.e., an A size sheet
has (roughly?) the same amount of "detail" as a C size sheet on
the plotter. B size print would equate to a D size plot?

I'll have to drag out a plotter and see.

(or, has my mental arithmetic slipped a gear somewhere along
this process?)

I think the hiccup is that printing single pixel width lines
does not work. I'll bet that at 300 dpi the finest useful to
print line is at least 5 pixels wide.
