Object optimized printing system and method
First Claim
1. A method for generating object optimized print data of an output image, comprising:
- inputting document data defining a document, the document comprising at least one page, converting the document data into a plurality of independent image objects, each independent image object having an object type, each page of the document comprising at least one of the plurality of independent image objects;
generating the object optimized print data for each page of the output image based on the at least one independent image object comprising each page and the object type corresponding to each independent image object.

Abstract
An object optimized printing system and method comprises a page description language decomposing system, a command instruction and data generating system and an image output terminal controller. The PDL decomposition system inputs a print file defining a plurality of pages in the page description language and locates the plurality of objects forming each page and their object types. Based on the determine object types and any explicit rendering commands in the PDL file, the PDL decomposition system automatically generates rendering tags for each of the objects. The rendering tags are used to control the command instruction and data generating system, the IOT controller and/or the image output terminal to optimize the printing by the IOT on an object-by-object basis. Based on the objects and the generated rendering tags, the command instruction and data generating system generates the differing types of data and the command instructions on a scanline-by-scanline basis. The generated command instructions and data are output to the IOT controller scanline-by-scanline. The data output to the IOT controller includes metabit data which is generated from the rendering tags. The metabit data output to the IOT controller is used to control various subsystems of the IOT controller and the IOT to optimize the printing characteristics of the IOT for each differing object on each scanline.
