Image forming apparatus performing trapping process when print data includes a plurality of pieces of image data and to superpose the adjacent pieces of image data and a determination unit that determines whether or not trapping attribute information, which indicates that the trapping process is to be performed, is attached to the pieces of image data on a piece by piece basis of performed color correction

摘要

An image forming apparatus performs a trapping process. The image forming apparatus includes an image processing unit that includes a determination unit, a color correction unit, a processing unit, an adding unit, and a generating unit. The processing unit performs the trapping process on the pieces of image data, on which the color correction has been performed by the color correction unit. The generating unit generates intermediate data in accordance with the print data including the pieces of image data, on which the trapping process has been performed. The image forming apparatus also includes a rendering unit that performs a rendering process on one or more of the pieces of image data on which the color correction has been performed by the rendering unit and on the pieces of image data for which tag information indicates that the color correction has been performed.
