Exact Duplication means transforming a Raster graphic file to Vector graphic, re-drawn in vector format looking as similar as possible to the actual one. Photo to Vector Drawings and Gradients to Vectors will not be the exact duplication of a vector because in this case, the vector graphic will be different than the original image.
