Description
Using the storage of member point dot matrix, the method for platemaking of output information and equipment technical field
The present invention relates to the method for platemaking and equipment using member point dot matrix storage and output information.Background technology
The process that plate-making belongs to before printing, is first made a plate, and the film or plate after plate-making are used to subsequently be printed on a large scale.In current plate making technical field, plate-making output equipment includes laser photocomposing machine, purple laser c TP (CTPs）, thermosensitive CTP, ink-jet CTP etc., its lithography process is usually such：Record is had after the rasterized original image sketch map for the graph text information to be exported, color separation, linked network processing, graph text information is adjusted to be transformed into mesh tune graph text information by continuous, that is linked network figure, then according to above-mentioned linked network diagram data, plate-making output equipment is recorded on film, CTP plates, so as to obtain printing version, as shown in Figure 2.
* color separation
Color separation refers to image being divided into e.g. green grass or young crops, fuchsin, Huang, black（CMYK) the gray-scale map with continuous tone of four kinds of colors.
The processing of Ginseng linked networks
, it is necessary to which original image is divided into Huang, product, green grass or young crops, black four-color image when being printed for coloured image, halftone technique is respectively adopted in colors, forms bianry image and carries out chromatography again.So, halftone technique is one of important technology of print field, and screening technology is also referred to as in printing industry.If Fig. 1 is exactly example that continuous toned image is handled by linked network.
Linked network（Also it is screening）It is exactly the process of the depth level of size the picture breakdown of continuous tone into multiple grids and with linked network site or the site density reflection actual color of image, so that graph text information continuous will be adjusted to be transformed into mesh tune graph text information.Since digital halftone technology comes out, amplitude modulation screening has successively been occurred in that（AM) algorithm, frequency-modulation screening（FM, is also random linked network）Algorithm and FMAM mixing linked network algorithm etc..
Site is considered as " ripple " in image screening, frequency is net number in unit length, amplitude represents site size.If center spacing is identical and change site size between keeping site, this image is called amplitude modulation screening image；If site size is identical on piece image, and the distance between site changes, then referred to as frequency-modulation screening image, is shown in Fig. 3.
The characteristics of amplitude modulation screening is that linked network site interval is fixed, and linked network site interval depends on linked network line number,
And linked network site is centrally located at grid element center, its size is the function of contrast information.The characteristics of frequency-modulation screening is that linked network site has multiple in the area equivalent to the grid of amplitude, and site size is identical, but position random dispersion is distributed.Using amplitude general books and periodicals product at present more.
For linked network, site size has difference.Here site size is a relative value, refers to the multiple ranks marked off after actual physical size is digitized.The shade that the eyes of people are seen is exactly the continuous quantity from black to white, and this is analog quantity, when will be in digital form（0/1 code）During with computer to represent from black to white, it is necessary to sample quantization, being subdivided into 256 grades from black to white, at this time just it can just represent 256 tonal gradations with a byte 8, it is easy to computer to store, and number of degrees is more, and level performance is abundanter.Generally, in order to show 256 tonal gradations, amplitude is sized to 256 numerical value between 0 ~ 255.
In the prior art, by black white image carry out amplitude modulation screening exemplified by, before linked network image as shown in Figure 4 A, after linked network image as shown in Figure 4 B, plate-making output after image as shown in Figure 4 C.From Fig. 4 B, linked network step is exactly to represent image by multiple sites that middle heart septum is fixed but size is different.
For amplitude modulation screening, single grid is divided into such as 256 cells and judges each cell with the presence or absence of image to obtain the numerical value between a 0-255 by being obtained by of site size.Here, the implication exemplified by 256 is to obtain 256 tonal gradations.If judging all there is image in all 256 cells, and site size is 255, if judging, all 200 cells all have image, then site size is 200, if and in the case of judging all no image of all cells, site size is 0, by that analogy.In other words, the size of site is a relative concept, represents that the area of the image in the grid surface area accounts for the ratio of whole grid surface area, highest rate is 255.
For frequency-modulation screening, site size is fixed, only represents that there is site the position again without site with numeral 0 or 1.
In this application, the concept of " site " results from linked network processing, in follow-up process, platemaking equipment will generate the corresponding output information in each site, and exported according to the information, to constitute final image, this is the processing feature of all existing platemaking equipments.
Ginseng stores site information
After linked network, for amplitude modulation screening, platemaking equipment is by the corresponding relation according to each default site size in the pattern memory of site and actual site micro-shape, the array data that each site is stored as being represented by 0 and 1 two-value.Fig. 4 D are a bitmap of the array data of Component units lattice A site, and its site size is 21, but actual storage is the bitmap being made up of 0 and 1 two-value.To frequency modulation
For linked network, direct storage 0 or 1 is represented that there is site the position again without site by platemaking equipment.
* plate-making exports site
Plate-making output equipment can be laser photocomposing machine, purple laser c TP, thermosensitive CTP, ink-jet CTP etc., and output intent can be chemical reaction method（Burning, dissolving, decomposition, gasification, blast）Or physical change method（Ink-jet etc.）.Because the figure of platemaking equipment final output belongs to dot chart, so " output point " hereinafter is exactly to constitute those points in dot matrix image, it is the minimum unit of dot chart.
When making a plate output, different platemaking equipments will form output point according to site information in the form of multiple hot spots, heat generating spot or ink-jet point.When making a plate output, platemaking equipment reads the bitmap in storing step above, do not launch or launch laser facula in the position according to the 0 of each position or 1 numerical value, form heat generating spot or ink-jet point, eventually form the actual printing figure of the cell A amplified in Fig. 4 E site.The site that Fig. 4 E are showed is symmetrical shape.
However, it is all more asymmetric that the sight shape of site, which has blunt, for amplitude modulation screening, in actual net-point printing figure.As shown in figure 5, the size in order to represent consecutive variations, even if Dou Shi Round shapes site in theory, actual site micro-shape is nor preferable symmetric shape.Such as each figure difference representing gradation value in Fig. 5 is 5,6 and 8.Such overall figure for printing obtained site not merely may be asymmetric（Fig. 5), and figure edge it is actually jagged（Fig. 4 Ε and 5), rather than desired Round shapes.Information graphic edge asymmetric He Bu Round in linked network site are slided, and this is totally unfavorable to performance high frequency graph text information, and printing looks that definition is not high, obscures.Further, since ink-jet point, heat generating spot and the usual Dou Shi Round shapes of laser spots, the inside for the single linked network site being actually formed can also have Xu Duo Round Xing Yu the micro gap formed between Round shapes（Fig. 4 Ε), it is not full.
Except the defect in terms of above-mentioned figure, in the prior art when storing amplitude modulation screening information, for example, the linked network frequency of one 800*600 millimeters of breadth is the 175LPI space of a whole page, ten thousand linked network sites about more than 2,200, if each amplitude modulation screening site is calculated by 256 output points, altogether more than hundred million output point about more than 50, to store the information of so many output point needs big memory space.Moreover, making plate-making output equipment ensure that the record accuracy of so many output point is also to have suitable technical difficulty, this is also the current plate-making expensive main cause of output equipment.
In the prior art, mainly influence of the various net hanging methods to plate-making picture effect that related patent application is studied emphatically, such as Chinese invention patent application CN1624583, the storage to output information of making a plate and the plate-making way of output do not propose more easily processing method.

It is of the invention with rasterisation of the prior art, color separation, linked network processing all same, and generation site information pattern and export the pattern of site difference in terms of the two.
The data storage after linked network is the form of a bitmap in the prior art, that is, with a series of 0 or 1 represents a site, Fig. 4 D are an one of cell A bitmap data.In the prior art, a series of 0 or 1 data that each site has can be stored according to predefined procedure in actual storage.Then in plate-making, each site is sequentially formed in the correspondence position of data 1 formation output point by not forming output point in the correspondence position of data 0.
In the case of amplitude modulation screening, figure after single net point imaging is exported in the prior art is as shown in Figure 4 E, it can be seen from the figure that, one linked network site of output is combined by 21 Ge Round shape output points, therefore not only there is gap between Ge Ge Round shapes inside the information graphic of site, and site information graphic edge is zigzag.
In the present invention, after linked network processing, platemaking equipment is according to the center of each obtained site and size generation member point lattice information, the member point lattice information includes the information of multiple member points, each member point information includes the position of member point, size, and the position of each member point, size information corresponds to the center that mesh adjusts linked network site in graph text information, size information, the position correspondence of each member point represents the ordinal position of an output point, the size value of each member point is two or more numerical value, each numerical value correspondence represents the rank of the physical size of an output point.
The linked network processing includes amplitude modulation screening processing, one kind in frequency-modulation screening processing and mixing linked network processing, wherein amplitude modulation mesh is obtained in amplitude modulation screening processing adjust graph text information, processing obtains frequency modulation mesh and changed the line map literary information in frequency-modulation screening, amplitude modulation is obtained in mixing linked network processing and frequency modulation mesh is changed the line map literary information, platemaking equipment will adjust graph text information according to the amplitude modulation mesh, literary information that frequency modulation mesh changes the line map literary information and amplitude modulation and frequency modulation mesh is changed the line map respectively obtains amplitude modulation member point lattice information, frequency modulation member point lattice information and mixing member point lattice information.In amplitude modulation member point lattice information, the position of each member point, size information correspond to amplitude modulation mesh and adjust the center of site, size information in graph text information, each member point size value is multiple numerical value, and the position of each member point is the center of each site.The data of these yuan of point will be stored during actual storage in sequence.In frequency modulation member point lattice information, the position of each member point, size information correspond to frequency modulation mesh and changed the line map the center of site, size information in literary information, and each member point size value is fixed two values, and one of numerical value is 0.
For example, in amplitude modulation mesh adjusts graph text information, the site size obtained at some position is 200 in number range 0-255, then member point size is also 200, both --- correspondence.In frequency modulation mesh changes the line map literary information, there is no site at some position, then member point size is 0, or has site, then member point size is 1.
Fig. 6 D is represent the member point hum pattern of single lattice site information, and it is 25 that one of cell A first lattice array data, which include member point size in position and member point size, figure,.
In plate-making, platemaking equipment is by according to the variable output point of member point hum pattern data output physical size.Here " output point " is exactly the minimum unit for being printed onto dot matrix image later on film or plate.According to each first point data, correspondence one output point of output.For example, for first point of a size 100, being set to the Round hearts using centre bit and exporting the physical size of a such as diameter as 1.5 μ π ι Round shape output points；So to first point of a size 200, the physical size of a such as diameter is exported as 3.0 μ π ι Round shape output points by the Round hearts are set to using centre bit.
Certainly, for the film or plate of different breadths, the magnification ratio of image is different, and the physical size of the actual output point of identical member point size correspondence output is possible to change.And the blunt difference according to parameters such as linked network line numbers of, the physical size of identical member point size correspondence reality output point is also by difference.
The size of imaging point is fixed in the prior art.For example, for the original graph that resolution ratio is 1440*1440, prior art will output size be 17.5 μ π ι output point, it is and unchanged.By contrast, the output point of platemaking equipment can have the sizes of consecutive variations at equal intervals in the present invention.Such as
Linked network frequency is 175 lines（Refer to per inch added with 175 netting twines）When, the maximum member point size of output is the correspondence output μ π ι Round shape output points of diameter 145.And according to the linked network frequency of 133 lines, the maximum member point size of output is the correspondence output μ π ι Round shape output points of diameter 191.
The implication of output point " physical size is variable " can be found in Fig. 7.Such as in the case where member point size span is 0-25, member point size be respectively 10,15,20 and 25 member point be outputted as sequence of positions fix but diameter for example be respectively 1.0 μ π ι, 1.2 μ π ι, 1.4 μ π ι, 1.6 μ π ι output point, if changing the film or plate of a breadth, same member point will be outputted as sequence of positions fix but diameter be for example respectively 2.0 μ π ι, 2.4 μ π ι, 2.8 μ π ι, 3.2 μ π ι output point.It is therefore to be understood that " size " of member point represents the relative rank of the physical size of an output point, specific physical size numerical value is not corresponded to.
Ruo Cai Yong Round shapes site, platemaking equipment of the invention can be controlled to export different size Round shape output points.According to Tuo Round shapes site, platemaking equipment of the invention can be controlled to export various sizes of Tuo Round shape output points.Specifically, the technological means such as injection electric size, control laser facula size that can be by controlling nozzle realize the change in size of above-mentioned output point.
Because the platemaking equipment of the present invention can export the output point of a variety of physical sizes, therefore single site just can be only represented during storage information with center and size.Compare Fig. 4 Ε and 6 Ε to understand, the linked network site that 256 data could be represented is needed in the prior art, in the present invention, it need to can only be represented with the position and size of one " first point ", so reduce memory space, plate-making also reduces the number of times of ink-jet, transmitting laser or heating when forming image, improve operating efficiency.
In print field, for the less image information of micro details, frequently with amplitude modulation screening mode, for the more character information of micro details, frequently with frequency-modulation screening mode.There is the situation of word again to existing image, frequently with mixing net suspension mode.And the platemaking equipment of the present invention both can apply to single frequency-modulation screening and amplitude modulation screening, it can apply to again while carrying out the mixing linked network situation of linked network using two kinds of net suspension modes of amplitude modulation and frequency modulation.
Fig. 8 Α are the present invention using memory module during mixing linked network, mixing linked network is while using both amplitude modulation screening mode and frequency-modulation screening mode, corresponding output when Fig. 8 Β is mixing linked networks, left figure is the situation of printing image information, and right figure is the situation of print character information.To the image information of left figure, using amplitude modulation screening mode, it is center and the size of the site that obtained member, which puts the position of information and size, and size is 25.To the text information of right figure, using frequency-modulation screening mode, obtaining member point information includes a series of digital 0 and 1.In the present invention, the storage mode under frequency-modulation screening mode can be compatible with the storage under amplitude modulation screening mode, that is, storage when both data can be stored together.
It is with the situation difference of amplitude modulation screening pattern, in frequency-modulation screening pattern, first two values for putting size for fixation, such as 0 or 1 in frequency-modulation screening, one of numerical value is fixed as 0, and another numerical value can remove other numerical value beyond 1.
During actual storage, data compression can be carried out for 0 position to data, be will not be described here.
In the present invention, plate-making output under frequency-modulation screening mode can be compatible with the plate-making output under amplitude modulation screening mode, because platemaking equipment can export the output point of a variety of physical sizes, the physical size covers the physical size of output point needed for the physical size and frequency-modulation screening of the output point needed for amplitude modulation screening.
Xu Yao Round point shapes when, method for platemaking of the invention and equipment output linked network site can realize the Hao Round points shapes of compare, the high-frequency signal of graph text information is fully ensured that.
Although being illustrated in the embodiment of the present invention by taking Round form points as an example, but it is also possible to suitable for site have other situations of different shapes, such as triangle, Tuo Round shapes, these can be realized by changing the mode such as nozzle form or laser facula shape.Laser plate-making mode for easily realizing change in shape, the net suspension mode that can be also changed using dot shape, and increase the shape information of each member point in member point information, so that the different situations of the various pieces according to composition image use different dot shapes in conversion, so as to realize best image appearance.
Member point lattice information in the present invention can be inputted by way of outside input, and be not limited by linked network processing and obtained.
In addition to above example, the present invention also has other numerous embodiments.The equivalent substitution or similar combined exchange that every those skilled in the art are done on the basis of the present invention belong to this patent protection domain.
