Using the zoom in function we see the effect of setting the brush shape to oval in the picture
above and below it is set to square. The Trap Highlights are set to green to clearly show the
resulting shape of the actual traps. In general the goal in trapping is to apply the needed
traps but to be as un-noticable as possible. It is generally agreed that the sharp corners
of the Square Brush in the traps make them more noticable than the smoother corners of the
Oval Brush thus detracting from the shape of the original artwork.
