Homebrew PCBs

My printer was clogged up with Mispro inks after few days of 
sitting. The far right, now black, was completely clogged up and 
having performed all kinds of cleaning tricks did not help. I 
Soaking in mispro cleaner for few days did not help. Mispro cleaner 
is useless. And please notice that my printer was brand new from 
C88+ that printed perfectly with Epson inks. I then tested that 
printer before conversion with mispro inks (cartridges in correect 
slots) and the picture was ugly. I cannot imagine how can anybody be 
satisfied with mispro colors!!!!!!!! Unless they do not care about 
colors but they do care about water sensitivity.  My intention is 
not dispute Stefan's contribution, it was great, I jsut want to tell 
you that that method is not what it seems to be. By the way: my 
quality of print on copper is 100%, superb, after heating up it is 
alos 100% but after etching some thin traces on a complex PCB were 
here and there underetched. For me it is not a big thing, maybe 1% 
maybe 2%. My problem is that that my brand new printer clogs up few 
days later. Mike
