Problems solved by technology

The main feature of its scanning is that after each unit area (300mmX300mm) is scanned, the next area is scanned. The data processing feature of the computer is that the graphic information data is divided according to the unit area. The advantage of this processing method is that the graphic information data The treatment method is simple, but the disadvantage is that the seam between two adjacent unit areas will be unstable. If the dots between two adjacent unit areas are exactly between 30%-60% of the sensitive dot area, then the seam Graphical and textual information data will show interference phenomenon, which will affect the effect of plate making

Embodiment 1

[0008] A plate making machine adopting the technology of the present invention, the graphic information data is divided into several small areas by the technology of the present invention, and the vibrating mirror scanning head performs fast scanning in the small areas divided out, and after scanning, the X-axis wire The rod guide rail and the screw guide rail in the Y-axis direction move the galvanometer scanning head to the next small area, and the high-precision positioning is achieved through the grating scales in the X-axis and Y-axis directions, and this action is repeated until the scanning of the entire area is completed.

Embodiment 2

[0010] The method of finite element analysis is used to segment the graphic information data. The first step is to determine the solution domain, that is, to calculate the network point density distribution of the graphic information data. The second step is the discretization of the solution domain, that is, the graphic information data is divided by the finite element network according to the distance of the dot diameter of 15um corresponding to the resolution of 2540DPI. The third step is to determine the state variables and control methods, which is to analyze the network point density in the network through row matrix statistics. The fourth step is the overall analysis to determine the segmentation plan, and then combine the following two points according to the dot density distribution obtained in the previous step: one is that the segmentation area is smaller than the maximum scanning unit area (300mmX300mm), and the second is that the graphic information at the seam has...

Abstract

A data processing method suitable for plate-setting machines. The technical feature of the present invention is that it adopts the analysis method of finite element to the segmentation processing of graphic information data, and analysis standard is the maximum unit area (300mm * 300mm) and graphic information dot density combined with galvanometer scanning, satisfying two points: the one is segmentation The area is smaller than the maximum scanning unit area (300mmX300mm). Second, the dot density of graphic information at the seam is preferably less than 30% of the dots or higher than 60%. Find a dot close to this value.

Description

technical field [0001] The invention relates to the technical field of mathematics and computer data processing, and is the core technology of a plate-making machine. The flat plate making machine with this design as the core technology is mainly used in the field of flexible printing, which belongs to the plate making equipment, and is the core technology of the key equipment for the development of flexible and environmentally friendly printing technology. Background technique [0002] Existing scanning technologies for flatbed platesetters: [0003] In the flat plate making machine, the scanning method combining platform linear scanning and galvanometer scanning is adopted. The galvanometer scanning head performs rapid scanning within a unit area (300mmX300mm). After scanning, the X-axis screw guide rail and the Y-axis direction screw The guide rail moves the galvanometer scanning head to the next unit area, and realizes high-precision positioning through the grating scal...
