Hi
The paper and supplier that I have been using is on the page you sent marked dib-bid and the suppliers name is shcfstore.
If you notice there is allot of similar type looking paper that others are selling which I cant vouch for because always used the people mentioned.
They told it was wax based paper, that why I originally bought it, maybe its not , but what I can assure is it works with the success rate stated otherwise wouldn't have bothered to pass the information on too you all.
This technique I am using isn't just for hobbies its also used for prototyping in my business.
If your wanting to try it I strongly suggest that you buy from the supplier I mentioned then you know you have something that works, otherwise you could well end up with a half shot job and be disappointed.
Regards
Dave

Hi Dave,
Thanks for this information.
I think your attempt to laser print onto copper is doomed to failure.
As far as I know there is no way of transferring the toner from the drum
to any conductive surface.
Can you describe the Heat Toner Transfer Paper you are using?
http://www.ebay.com/bhp/heat-toner-transfer-paperIs it a gummed paper, in which there is a clear coating of perhaps
slightly cracked or crackable hard gum, which can be dissolved in water?
This is traditional dextrin gummed paper, as used in stamps and
lick-to-stick envelope flaps. It is also sold in jars as "flap gum".
If so, I had all sorts of trouble with such paper due to the toner
jumping around the place. This depended on how dry the paper was - too
dry and the toner would not stick to it long enough to be melted into it
by the fuser roller.
Is it something which water will not touch?
In the write-up of your work by Rick Sparber:
http://rick.sparber.org/electronics/el.htmCopper Etching with Laser Printed Artwork, by David Pickering
http://rick.sparber.org/electronics/cel.pdfyou mention using the Heat Toner Transfer paper and that after freezing
it, it simply peels off the copper and toner, without any water. I think
this is a most remarkable thing. I plan to order some of this paper.
Thanks Rick for summarizing Dave's technique, as elaborated in these
discussions. I suggest you put a link in your document to this fine
discussion forum / mailing list.
