Th swell paper is useful for general diagrams such roads and vague
outlines.  The lines are clear, but soft and fat, so detail is hard to do
with this type of paper.  One must blow the printed OrCAD (or whatever)
copy up, and also redo the text labels.  this paper requires a special
"burner" to cause the tiny bubbles which coat the paper to expand under
intense heat, and it is these bubbles which form the tactile image the
reader feels.  I tried to use an intense light once and focus it on the
darkened surfaces of the swell paper (the dark parts have the image ink on
them), but no go.  The burner--like a toaster almost--is needed.  I've
heard of people using a laser printer for the job, but others fear that
the paper would melt inside the laser printer.
