Abstract:
1. An apparatus, comprising: a document base unit that provides a first set of data representing one or more first strip sections corresponding to a portion of a document that does not change wherein the one or more first strip sections is stored in a base data file; a variable data unit that obtains information for a second set of data representing one or more second strip sections corresponding to one other portion of the document that does change, wherein the obtained information comprises updated information about at least one of a first identifier corresponding to a mask layer and a second identifier corresponding to a foreground layer, the first and the second identifier each included in the one or more second strip sections associated with the second set of data, wherein the one or more second strip sections is stored in a variable data file, and wherein the obtained information comprises retrieved data relating to the one or more second strip sections stored in the variable data file from a variable document description file comprising data related to name and location of the variable data file, and strip sections stored in the variable data file wherein the obtained information replaces the first identifier and the second identifier in the variable data file with corresponding location information; wherein the location information is updated in the variable data file to refer to a rasterized base data file and a rasterized variable data file; imaging information describing rasterization levels is added to the variable document description file; wherein the appropriate rasterization level the base data file and the variable data file should be rasterized at is determined based on the imaging information; and a document combination unit that combines the first set of data and the second set of data with the obtained information to form a combined set of document image data for the document.
