[quote simonm]I tried scale up a plan to double the size with a photocopier (on a Xerox WorkCentre Pro 128). What I found is that it was distorted in one direction. The width was accurate but the length was increased by about 2% (there is an accurate grid on the plan). Given that there has to be a lens in there somewhere, I can understand that it happens. The question is whether there are simple ways of getting around this issue. Do any copiers with a zoom function have a way of correcting the distortion? I would guess that if the copier accepted an original in the center of the scanning area instead of at the edges that that would pretty much solve it.
(fwiw the plan is a guitar outline to scale and I would like to get it as accurate as possible as my idea is to stick the enlarged plan to thin plywood and cut along the line to make my template).
not necessarily, it's not a simple lens, remember, there is a slide that moves back and forth each time you scan/copy. There are probably one or more cylindrical lenses in there, it's not as simple as enlarging an image with a normal lens.
But the trick I posted above should work.
