I'm new in this news group so forgive me if this has been asked before.
I recently came to a point where I have to produce a good PCB.
The easy method of drawing the tracks and the pads with a pen is not very good
in compicated or/and fast circuits so I'm after a better but easy method of
doing it.  Some one helped me by given me a book called "PCB made easy" but
fails to give details of what chemicals and sort of things there exist in the
market (in U.K.).

The usual photographic method of transfering the layout to a film is very
undesireable by me as I'm sort of dark-room and equipment.
Has any one a good solution for my problem?

Is it posible to photocopy the piece of paper with the track layout on a
clear plastic film used on overhead projectors and use this as the film
plased on the premade positive photoresist PCB and then to expose that 
in UV light ?

Thanks in advance.


P.S. Please forgive my English, as I'm Greek.
