But it's just an impression, caused by the expansion of the unrolled sides.
Will the reverse operation also be possible? - Create the flat label and produce its rolled version?
It is clearly visible in the curvatures (upper and lower) an accentuated pixelation.
The sharpness obtained was excellent!
The loss of aspect ratio is perceptual.Technically, the final result should be 1.57x (π/2) wider than the bottle/can. It is however possible that the original design uses a slightly widened aspect ratio to account for the perceptual shrink cause by the wrapping on a cylinder.
Yes, doing the same to wrap on cylinder is quite easy (easier than Filters ➤ Map to object (cylinder), but without some perspective effects of course).
Pixels on the edges are stretched over 10x.
