Hi, Im looking at the canon Pixma iP4300 printer
but think il take advantage of getting a test print from it first,
I want to try and see if it can print a codewheel 50mm diameter with 2000
lines,
ive tried a few free cad packages and created simple drawing with 2000
'spokes' but cant seem to find a way of getting it to a jpg file
without such loss of resolution the spokes are merged into 1 circle,

anyone know of a good proggy to create a jpeg file like this ?
or even know where a jpg file like this is or as good a test print ?

Ive scanned an existing codewheel but its not very good even though I
have
1200dpi scanjet 5300c, the actual lines are too fine to see with a naked
eye, you can see them on the scan but not well enough defined for
printing.

I want to make a second code wheel with 1 less lines than the other.

whats a codewheel? Something from the Enigma machine?

Ha sounds like it could be lol, but no its just part of a rotary encoder
