Re: image transfer
For UV, u need photoresist which is normally quite expensive, u put a coat of photoresist material on the copper board, take negative print of the circuit on transparency (the areas where there is no copper r printed as black, and copper areas remain transparent), put the print on the photoresist coated copper board, expose to UV and wash off.
For track widths down to 20 mils, u can use toner transfer which is cheap but requires a bit of practice. Many illustrated tutorials exist for it, just google it
