PCBs

[Mikko Helin]

What kind of tone transfer sheets do you actually use? I have only
used usual overhead transparencies (for photo copier/laser printer),
and with these you always have to do some repairs after ironing.
Has anybody actually tried these paper sheets by Dyna-Art
(www.dynaart.com), sold by Digi-Key and Mouser?
