Default Re: Drawing Trader Sheets back in the day.

I was a circuit draughtsman in the late 1970's. Mike T has it pretty much bang-on except our Master copies were made in the same dyeline machine as the blueprints but on sensitised film.
Rötring pens & lettering stencils were standard where I worked with the addition of some in-house symbol templates made to cope with certain components which were not on the commercial stencils.
I used an A0X board with a draughting machine and we used A0 film for all circuits which were dyeline printed full-size, folded and placed in every product.
