HI
Medical film printer i see was limited to 325DPI
it use kind of thermal film so good process but lack of resolution ..
I just but a new xerox solid-ink "Wax" printer
1-) True 2400DPI resolution
2-) ink was wax so it etch and for sure developer resist to
i see on this forum many user use very thin pcb on that printer
for direct pcb printing whit good result
but my idea was use a exposed DIAZO film (microfiche)
then develop it ,wax will serve as developer resist
so result will be 2400 DPI diazo film just like real pcb shop ;-)
3-) this printer use full length printing head so dot registration
was perfect ,it actually print image on rotating drum then
transfer it to the paper ,this was made a quite low temperature
(65DeG c) so this may not pose problem of film shrink
4-) it quite easy to transform it in all back printer by loading
Black ink block on all 4 tray ,so by manipulate the postscrip image it possible to have 4 wax dot think by pixel ,so in theory 3 time more opaque dark
5-)if all above fail A4 size drum will make a perfect drum for
a DIY protoplotter ,since it well balanced ,have servo motor for drive it and knot it precise position
will post result when i receive/test the printer
if some one was interested this was in deep explanation of how this printer work , that reading tell me that it may make real nice artwork printer for pcb ..
