Problems solved by technology

However, in the prior art, the rasterized dot matrix for variable data printing is stored independently in units of pages, and the same part of content in each page is repeatedly stored, which consumes a large amount of storage space and cannot meet the requirements of fast printing of variable data. Require

Embodiment 1

[0039] Embodiment 1 An application for processing PS jobs from a VDP application, including rasterization processing, rasterization lattice partitioning, recognition reuse, compression, storage and other processes. Since the general PS description does not define element reusability, even if the same image is placed in the same position on the first page and the second or subsequent pages, PS will describe the image data separately in the description of each page instead of referencing the same image data, so it is difficult for the RIP rasterization process to identify which elements are to be reused. In order to reduce the repeated compression and storage of the same rasterized dot matrix data, the method for storing the rasterized dot matrix of the variable data printing page provided by the present invention is used to process the PS operation of the VDP application. The specific process is as follows:

[0040] 1. Submit the PS job of the VDP application to the RIP.

Embodiment 2

[0055] Embodiment 2 processes the PDF job from the VDP application, including rasterization processing, rasterization lattice partitioning, recognition reuse, compression, storage and other processes. In a PDF document, an image is generally defined as a resource and has a unique PDF object ID (Object Identifier). Therefore, when the same image is used multiple times, the image bitmap data will not be described repeatedly each time it is used. Citation description. In the process of parsing the content of the page, when RIP encounters an image primitive, it determines and assigns a unique reuse object ID according to its PDF object ID, current coordinate transformation matrix (CTM) and clipping (Clip), and adds this information to to the list of job-level reusable resources. If the PDF object ID, current coordinate transformation matrix (CTM) and clipping (Clip) of the currently processed image already exist in the reusable resource list, they will not be added repeatedly, an...

Embodiment 3

[0076] Embodiment 3 processes PPML / VDX jobs from VDP applications, including rasterization processing, rasterization lattice partitioning, recognition reuse, compression, storage and other processes. In traditional PS and PDF documents, there is generally no explicit definition of which elements are reusable, but in PPML / VDX documents, those graphics elements that are reused many times are explicitly defined as reusable elements. Although in figure 2 The static text 1 in the variable data page template shown in the table is a constant data element and can be reused. However, if the VDP job applying this template generates a PDF, the content of the static text 1 will generally be repeatedly described in the content flow of each page, so Reuse content cannot be identified without a final rasterized bitmap comparison. And if PPML / VDX is generated, static text 1 will be defined as a reuse object (REUSABLE_OBJECT), and its content will only be described once. In this way, the bl...

Abstract

The invention discloses a storing method of a rasterization lattice of a variable data printed page. The method comprises the following steps of: generating the rasterization lattice of the variable data printed page by a raster image processor RIP; carrying out block processing on the generated rasterization lattice according to a set block strategy, and setting a unique block identification for each block according to the set regulation of block identification; determining whether the blocks in the current page are same with the corresponding blocks with same block identification in the front page; if so, using the corresponding blocks as reference blocks and storing page identification of the page where the block identification and the reference block are located; if not, storing the block identification and block lattice data contained in the blocks and recording the storing positions. The storing method and the system can reduce the data storage capacity of the rasterization lattice of the variable data printed page, save storage space and cost and can improve the speed of storage and access.

Description

technical field [0001] The invention relates to the field of computer data storage and compression, in particular to a storage method and system for rasterized dot matrix of variable data printing pages. Background technique [0002] With the development of digital printing, not only is the application of color printing more and more widely, but also the printing speed is getting faster and faster, making variable data printing suitable for personalized printing possible and increasingly popularized. The characteristics of variable data printing are: personalized content, which can be different from sheet to sheet; templates and databases can realize rapid typesetting, and a large number of thousands of pages can be generated. At present, variable data printing has been widely used in finance, postal services, telecommunications and other industries. The main applications include: personalized receipts, personalized bills, personalized advertisements, etc. [0003] In the p...
