Provided is a print data processing apparatus including an intermediate data acquisition section that acquires intermediate data which is generated from document data described in a page description language and includes plural image elements, an extraction section that extracts image elements of a watermark from among the image elements of the intermediate data acquired by the intermediate data acquisition section, a deformation section that deforms each of the image elements of the watermark extracted by the extraction section into a shape that does not include an overlapping portion between the image elements of the watermark, and an output section that outputs an image element group of the watermark deformed by the deformation section, to an image data generation device that generates image data for a printing device from the intermediate data.
