1. A method for generating multiple bit maps suitable for high-speed printing or plate-making comprising the steps of:

  • (a) generating a page description code representing a template, said page description code defining at least one variable data area and said page description code further defining a graphics state corresponding to said variable data area, said graphics state including at least one attribute which controls the appearance of variable data in said variable data area;

    (b) executing said page description code to generate a bit map of said template, and during said execution, identifying said variable data area defined by said page description code and reserving said graphics state corresponding to said variable data area upon said identification;

    (c) retrieving variable data;

    (d) associating said variable data with said graphics state corresponding to said variable data area;

    (e) applying said graphics state corresponding to said variable data area to said variable data to generate a variable data bit map; and

    (f) merging said variable data bit map with said bit map of said template;

    wherein said graphics state corresponding to said variable data area is applied repeatedly to variable data to generate a multitude of variable data bit maps without the need to repeat said executing step (b).
