Abstract
In a printing system, a hue shift compensation method includes the steps of: printing in a first direction a first color having a first color composition; printing in a second direction a plurality of second colors having varying color compositions; measuring with a color sensor the first and second colors; selecting one of the second colors approximating the first color and having a second color composition; and storing data corresponding to the second color composition as direction dependent color map data for use in printing in the second direction.
