I have been successful in copying decals and found a competent printer for
reproduction. Using a digital camera and perspective correction software,
stitching software and Photoshop you can do the same. The trick to start is keeping
the camera parallel to tubes as you rotate around them. Each image is then
corrected for plumb and then stitched, sized and detailed.
I then send the file to the decal maker. Only wish I had more original
cycles to copy.
