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).

Abstract
A method for printing variable data with a page description language, which enables the graphics states for a page of variable data to be defined and stored; and which enables the stored graphics states to be associated with items of variable data from a database, so that once defined, the graphics states can be used to print multiple pages of variable data. The method of the present invention is implemented by means of a control task, which executes in a printer in conjunction with a page description program, to identify variable data areas in the program, and store the graphics states for the variable data areas as they are defined by the program. After the program has terminated, a merge task associates items of variable data from a data file with the graphics states, generates a bit map for each variable data area, merges the bit maps with the page template, and outputs the page from the printer. Accordingly, in the method of the present invention, bit maps for multiple pages of variable data are generated from a single page description program.

14. A method for generating a bit map suitable for high-speed printing or plate-making comprising the steps of:
-
(a) generating a page description code representing a template; (b) identifying a variable data area of said template during execution of said page description code, said execution of said page description code generates a bit map of said template; (c) interrupting execution of said page description code upon identifying a page description code point command; (d) storing a graphics state corresponding to said variable data area; (e) generating a font cache in accordance with said graphics state; (f) linking said graphics state and said font cache with said variable data area; (g) reserving said graphics state and said font cache in a database; (h) resuming execution of said page description code beyond said print command; (i) reiterating steps b-h until execution of said page description code is complete and said template bit map has been generated; (j) accessing a variable data file; (k) identifying a variable data area for said template from said variable data file; (l) accessing said graphics state and said font cache linked to said variable data area; (m) reading data from said variable data file; (n) generating a variable data bit map of said data using said font cache and said graphics state; (o) merging said variable data bit map into said template bit map; and (p) reiterating steps k-o for all variable data areas of said template; whereby said graphics state and said font cache are used repeatedly to generate a plurality of variable data bit maps without the need to repeat said steps (b) through (i). - View Dependent Claims (15)

16. A method for generating a plurality of bit maps suitable for high-speed printing or plate-making comprising the steps of:
-
(a) generating a page description code representing a template; (b) executing said page description code to create a template bit map, said executing step generates a graphics state for each data area defined by said page description code; (c) during said executing step, identifying at least one variable data area defined by said page description code and saving in a database said graphics state corresponding to said identified variable data area; (d) storing said bit map of said template; (e) accessing a merge file containing a plurality of data records of at least one variable data field type; (f) associating said variable data field type in said merge file with said saved graphics state; (g) generating a variable data bit map of each said variable data records of said variable data field type by applying said saved graphics state to each of said variable data records; (h) merging each of said variable data bit maps into said template bit map to create the plurality of bit maps suitable for high-speed printing or plate-making; whereby said saved graphics state is applied repeatedly to said variable data records to generate a plurality of variable data bitmaps without the need to repeat said executing step (b). - View Dependent Claims (17, 18, 19)

20. A method for generating a plurality of bit maps suitable for high-speed printing or plate-making from a page description code representing a template and defining at least one variable data area, and from a merge file containing a plurality of data records of at least one variable data field type, the method comprising the steps of:
-
executing a page description code interpretive program, said interpretive program generates graphics states for each data area defined by said page description code; executing a control task in conjunction with said interpretive program, said control task identifies said variable data area defined by said page description code and reserves said graphics states generated by said interpretive program for said variable data area, said control task generates a template bit map defined by said page description code, and after the completion of said interpretive program, said control task saves said template bit map in memory; and executing a merge task upon completion of said interpretive program, said merge task generates variable data bit maps for said data records in said merge file by applying said reserved graphics states to said data records, and said merge task merges said variable data bit maps with a separate copy of said template bit map to create the plurality of bit maps suitable for high-speed printing or plate making; whereby said reserved graphics states are applied repeatedly to said data records to generate said variable data bit maps for said data records without the need to repeat said steps of executing a page description code interpretive program and executing a control task in conjunction with said interpretive program.
