Abstract
A kind of data processing method suitable for plate printing machine.The present invention to be technically characterized in that it uses the dividing processings of graph text information data the analysis method of finite element, analytical standard be the maximum unit area (300mmX300mm) and graph text information dot density in conjunction with vibration mirror scanning, 2 points of satisfaction：First, divided area is less than maximum scan unit area (300mmX300mm), second is that site or site higher than 60% that the graph text information dot density of seam crossing is preferably lower than 30%, if graph text information should look for the site close to this numerical value without the site of this numerical value as possible.
Description
Technical field
The present invention relates to the core technologies that mathematics and microcomputer data processing field are plate printing machine.With the design
It is mainly used in flexible printing field for the plate printing machine of core technology and belongs to platemaking equipment, be flexible environment friendly printing technology hair
Core technology in the key equipment of exhibition.
Background technology
The scanning technique of existing plate printing machine：
The scan mode being combined using plateau linear scanning and vibration mirror scanning in plate printing machine, vibration mirror scanning head are existed
It is quickly scanned in unit area (300mmX300mm), is led by the leading screw of X-axis lead screw guide rails and Y direction after scanned
Vibration mirror scanning head is moved to next unit area by rail, and high accuracy positioning is realized by X axis and the grating scale of Y-axis,
Such action is repeated until the entire area end of scan.Its scanning is mainly characterized by each block unit area
Next piece of area scanning is being carried out after (300mmX300mm) is scanned, the data processing features of computer are graph text information numbers
It is divided according to according to unit area, the advantages of this processing mode is that graph text information data processing method is simple, but disadvantage
It is that the seam crossing between two neighboring unit area can be unstable, if the site between two neighboring unit area just exists
Between sensitive site area 30%-60%, then seam crossing graph text information data can represent interference phenomenon, effect of making a plate is influenced.
Invention content
The purpose of the present invention is exactly so that plate printing machine is reached seam crossing graph text information data by using the technology of the present invention
Be not in interference phenomenon, plate-making effect is made to reach best.
The technology of the present invention is realized in the platemaking machine being combined using plateau linear scanning and vibration mirror scanning, picture and text letter
Segmentation of the data Jing Guo the technology of the present invention is ceased, is processed into several small areas, vibration mirror scanning head is in the small area split
It is quickly scanned, vibration mirror scanning head is moved to by the lead screw guide rails of X-axis lead screw guide rails and Y direction after scanned next
A small area realizes high accuracy positioning by X axis and the grating scale of Y-axis, repeats such action until entire area
The end of scan.
The present invention's is technically characterized in that it uses the dividing processing of graph text information data the analysis method of finite element, point
Analysis standard is the maximum unit area (300mmX300mm) and graph text information dot density in conjunction with vibration mirror scanning, meets at 2 points：One
It is that divided area is less than maximum scan unit area (300mmX300mm), second is that the graph text information dot density of seam crossing is best
The site or site higher than 60% for being less than 30%, if graph text information should be looked for as possible without the site of this numerical value it is close
The site of this numerical value.
Specific implementation mode：
Embodiment 1：
A kind of platemaking machine using the technology of the present invention, segmentation of the graph text information data Jing Guo the technology of the present invention, if being processed into
A dry small area, vibration mirror scanning head are quickly scanned in the small area split, it is scanned after by X-axis lead screw guide rails
Vibration mirror scanning head is moved to next small area with the lead screw guide rails of Y direction, by X axis and the grating scale of Y-axis come
It realizes high accuracy positioning, repeats such action until the entire area end of scan.
Embodiment 2：
Graph text information data are split using the method for finite element analysis, the first step is to determine that solving domain calculates
The dot density distribution situation of graph text information data.The discretization that second step is to solve for domain be graph text information data according to
The distance of the corresponding site diameter 15um of resolution ratio of 2540DPI is divided through row mesh of finite element.Third step is to determine that state becomes
Amount and control method are the dot density situation data in network being precipitated through row matrix statistical in network.4th step is total
Body analysis determines splitting scheme, and the dot density distribution situation asked according to previous step is in conjunction with following two points：First, segmentation
Area is less than maximum scan unit area (300mmX300mm), second is that the graph text information dot density of seam crossing is preferably lower than
30% site or site higher than 60%, if graph text information should be looked for without the site of this numerical value close to this numerical value as possible
Site, the final scheme for determining segmentation.The data divided are sent to according to certain sequential logic on laser scanning head
Complete the scanning of general image.
By practical printing verification, can get a desired effect.
