Technical drawings used to be made on a tough, transparent paper and were then reproduced photographically. My guess would be that the copier at Lesney required the original to be inserted into the copier reversed in order to produce copies the right way round. However, one day, someone simply forgot, resulting in the drawing you now have..tjlglass wrote:Cheers Kev, why would this be inverted ?
I believe what you have there is the master technical drawing on translucent paper (as Hugh mentioned) This drawing would have then been placed face down onto chemically treated photo reactive blueprint paper and exposed to UV light. The end result, being a blueprint copy of the drawing, with a dark background,where the light passed through and white lines appearing, where the light was blocked by the original drawings lines, all turned the right way around. The blueprint would then be washed, to keep the white lines of the drawing, from exposing any further.Idris wrote:Technical drawings used to be made on a tough, transparent paper and were then reproduced photographically.
