Patent ID: 8810853

Claim:
A print data processing apparatus in a printing system for producing prints including a fixed area having identical contents throughout a plurality of pages, and a variable area having different contents for each of the plurality of pages, comprising: a page data creating apparatus for creating page data expressing contents to be printed in a page description language; and a rasterization processing apparatus for converting the page data into raster data; wherein the page data creating apparatus includes: an allocating condition setting device for setting allocating condition information for use in allocating page constituent elements expressed by objects into prints, to each of the objects as content information; a correction information embedding device for embedding, in the page data, as precondition information linked to allocating conditions of an object relating to a bar code to be allocated to the variable area, bar-code correction information indicating that the object is to be corrected; a common object defining device for defining, outside the content information, bar-code constituent elements provided for each type of bar code to express the bar code, as a common object for composing a different bar code for each page, to which the plurality of pages refer selectively; and a page data generating device for generating page data including the precondition information and the common object; and the rasterization processing apparatus includes: a correction information searching device for searching the precondition information to check whether the bar-code correction information is embedded therein; a resolution acquiring device for acquiring a printing resolution corresponding to the type and allocating conditions of the bar code when the bar-code correction information is detected by the correction information searching device; a correcting device for determining an amount of correction based on the type of bar code, and the printing resolution acquired by the resolution acquiring device, and correcting the bar-code constituent elements; and a raster data generating device for generating raster data by composing a bar code using the bar-code constituent elements corrected by the correcting device.
