A soft proof system includes a display module and a manager. The display module displays a visual representation of a print product, and a color array expressing a tolerance range of a color component of the visual representation and a target color within the range. Via the manager, a visualization function produces the visual representation and the color array according to a soft proof array. A tolerance selection function, associated with the display module, enables selection of the tolerance range for at least a portion of the print product, wherein the selection is expressed on the display in the visual representation and in the color array.
