But I had to stop this sort of relaxation between my main win-software works. Even postings to Piclist are now problems because of the lack of time since I've new customers to my program.

Regarding ink, you can try deferent options when printing: micro- weave, glossy paper, film etc. Maybe pcb heat or UV treatment before etching will work. Please, if you succeeded with ink, drop a message to the List. Mike. -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
