Embodiment Construction

[0053] The specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0054] The following is an explanation of the principle of the implementation of the present invention, figure 1 It is a schematic diagram of the data stream transmission of the present invention. As shown in the figure, the print job data stream is interpreted by the RIP controller to form an intermediate file stream, and is distributed to the corresponding RIP device after passing through the distributed internal subnet. The RIP device rasterizes the intermediate file. After conversion, the raster dot matrix data is formed and then transmitted to the high-speed printout device for printing.

[0055] figure 2 It is a schematic diagram of the data transmission process of the present invention. As shown in the figure, the main steps of the data transmission of the present invention are:

[0056] Step 201: Initialize the data transmission module, the RIP...

Abstract

The invention discloses a distributed raster image processing data transmission system and method for graphic image printing processing. In the method of the invention, after the raster image processing controller interprets the print description language into file data, it is distributed to A raster image processor performs rasterization. In the system of the present invention, the raster image processing controller is connected to multiple raster image processors through the first data transmission module. After the raster image processing controller interprets the printing description language into file data, the first data transmission module transmits Distributed to a raster image processor for rasterization. After using the present invention, the data transmission speed is fast, and the network resources are less occupied, which effectively improves the acquisition speed of the raster image processing system for processing job data sources, improves the processing speed of the distributed raster image processing system, and satisfies the requirements of high-speed printing output devices. Require.

Description

Technical field [0001] The invention relates to a printing data transmission system and method, in particular to a data transmission system and method using distributed raster image processing. Background technique [0002] RIP (Raster Image Processing), the full name of raster image processor. The role of RIP in the color desktop publishing system is very important. It is related to the output quality and speed, and even the operating environment of the entire system. It can be said to be the core of the color desktop publishing system. The main function of RIP is to interpret the various images, graphics and text in the computer-made layout into dot matrix information that can be recorded by a printer or imagesetter, and then control the printer or imagesetter to record the image dot matrix information on paper or film. [0003] RIP is usually divided into hardware RIP (hard RIP) and software RIP (soft RIP). There are also RIPs that combine software and hardware. The hard RIP i...
