Archive of the former Yahoo!Groups mailing list: Homebrew PCBs

Hi,
I've been reading for a while but have never contributed so I hope you
don't mind me asking a
question. Here at the university I've all the facilities for pcb
manufacture but my printer is to be
replaced with a new one. The printer that I have, although it is
1200dpi, spreads the ink to the
extremes of tracks and solid copper areas, this as you know can cause
pitting. It also stretches
the transparencies I use ( I've tried others with the same results ).
This is OK for small or
undrilled pcbs but for large i.e. > than 100mm by 160mm that have
already been drilled this causes
line up problems. The software I use, Target 3001, enables me to
compensate for printers that
don't print true 100% but the stretch in my print outs vary each time, I
guess from the heat in the roller.
So my question is does any one have any recommendations for a printer.
The printer I use at the moment is an Hp laserjet 1200.
Thanks in advance
Susan
