Vectorizing continuous tone images is often met with color palette reduction and visual artifacts. Half-tone images, on the hand, have constant patterns in their tones, which would intuitively lead to the conclusion that these images can be vectorized with greater success, if without any visual artifacts at all.   Failing to find any sufficient comparisons against vectorizing continuous tone images and half-tone images on separate research, I now pose this: What behaviors occur during vectorization of raster half-tone images?
