1. A print processing apparatus comprising: an object information identification section for receiving drawing data including a specific object and identifying said specific object as data for drawing a specific object from the drawing data; a gradient adding section for adding a gradient to said drawing data on a per pixel basis; and a screen processor for performing screen processing including setting of density to which a density parameter is applied based on said gradient; wherein said screen processor performs specific screen processing for setting density to specific data out of said data for drawing a specific object by applying, as a density setting parameter, a parameter shifted to a lower density than said drawing data except said specific data.
