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. |

1. An image forming apparatus comprising:
an image processing unit; and a rendering unit, wherein the image forming apparatus performs a trapping process that, when print data includes a plurality of pieces of image data, causes boundary portions of the adjacent pieces of image data to be superposed with one another, wherein the image processing unit includes
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,a color correction unit that performs color correction on the pieces of image data, for which it has been determined by the determination unit that the trapping attribute information is attached,a processing unit that performs the trapping process on the pieces of image data, on which the color correction has been performed by the color correction unit,an adding unit that adds tag information, which includes a piece of information indicating whether or not the color correction has been performed by the color correction unit, to each of the plurality of pieces of image data included in the print data, anda generating unit that generates intermediate data in accordance with the print data that includes the pieces of image data, on which the trapping process has been performed by the processing unit, and wherein the rendering unit refers to the tag information of each of the pieces of image data in the intermediate data generated by the intermediate data generating unit, performs the color correction on one or more of the pieces of image data to which the tag information, which includes the piece of information indicating that the color correction has not been performed, has been added, and performs a rendering process on the one or more of the pieces of image data on which the color correction has been performed and on the pieces of image data to which the tag information, which includes the piece of information indicating that the color correction has been performed, has been added. |
