You must have noticed that when we trace any image to get the vector effect in corel auto trace versions 10 onwards, there is a visibility of white thin lines outside the every vector traced element. So How to get rid of those thin too many white outlines or you can say tiny thin white gaps?

Here is a  very simple answer for this. Just overlap the same traced graphic over the first traced one and your traced vector graphic will be sharp and crisp. ;)
