Description
The present invention relates to photographic plate-making equipment, particularly the linear array or the face matrix plate making exposure head of use such as photosensitive lithographic printer or photosensitive lithographic plotting apparatus.
Dot-matrix printer is the most frequently used external unit of present robot calculator, during work under the control of computer program, the striker formula dot matrix print head on it can along laterally toward, return and the output medium that vertically moves for example on the printer paper according to original copy content output print result.Print result more precisely is coated with the printing ink on the ink ribbon to dye by striker formula dot lattice printing printing solenoid actuated print needle bump ink ribbon in front and for example forms on the printer paper at output medium, because colour band expansion, the influence of factors such as printing ink infiltration, actual output resolution ratio is much lower than the resolution index that print needle or mechanical navigation system can provide, the nominal resolution of better slightly dot-matrix printer is per 25.4 millimeter 360 point on for example present market, but the actual effect of printout is that the printout result of per 25.4 millimeters 240 laser printer or liquid crystal printer is clear not as nominal resolution still, and this has limited dot-matrix printer such as the picture and text plate making, P.e.c. plate-making etc. are such requires high resolving power, the deep application of the application of high definition.
Task of the present invention is to propose linear array or the face matrix plate making exposure head that photographic plate-making equipments such as photosensitive lithographic printer or photosensitive lithographic plotting apparatus are used.The striker formula dot matrix print head that linear array that proposes with the present invention or face matrix plate making exposure head replace in the previous dot-matrix printer simply just can constitute practical photosensitive lithographic printer, similarly also can constitute practical photosensitive lithographic plotting apparatus, or photosensitive lithographic printer that otherwise designed is new according to the present invention or photosensitive lithographic plotting apparatus etc., when being used for photosensitive lithographic, they can on photosensitive mediums such as sensitive film, output simultaneously satisfy high resolving power, the many exposing light beams that high definition requires, exposure form to sensitive film is one dimensional linear array or two-dimensional array, is suitable for the picture and text plate making, the requirement output high resolving power that P.e.c. plate-making etc. are such, the film negative of high definition or the occasion of photosensitive mask are used as output device.
Linear array that the present invention proposes or face matrix plate making exposure head are mainly assembled device and shell etc. by electric light source, optical shaping and are formed.Electric light source has the compound controllable characteristics of simulation or pulse or analog pulse, photographic plate-making equipment just can be regulated and control electric light source by interface and driving circuit according to the original copy content under the control of computer program in complete forme-producing system like this, such as brightness, tone or the open and close moment etc. of modulation output beam; The light beam that electric light source sends is a high resolving power to the exposure form of sensitive film, the one dimensional linear array of high definition or two-dimensional array form, if can not directly satisfying this requirement, electric light source need the suitable optical shaping of adapted to assemble device, for example will arrange arbitrarily with light transmitting fiber, the exposure form that the output beam shaping of the electric light source of any size is rearranged into sensitive film is a high resolving power, the one dimensional linear array of high definition or the form of two-dimensional array, the output beam convergence of inciting somebody to action the electric light source that resolution is lower even very low originally with converged optical lens narrows down to the high resolving power that satisfies ctp request, high definition level etc.In addition, suitable shell together with finish with main frame between the cable that is connected or optical cable or connector also be necessary.
Below in conjunction with concrete example and accompanying drawing structure of the present invention and realization are further described:
Accompanying drawing 1 is a synoptic diagram of realizing the linear array plate making exposure head that the present invention proposes with light emitting diode;
Accompanying drawing 2 is synoptic diagram of realizing the face matrix plate making exposure head that the present invention proposes with light emitting diode;
Accompanying drawing 4 is the synoptic diagram with the face matrix plate making exposure head of the firm and hard existing the present invention's proposition of liquid crystal light valve;
Accompanying drawing 5 is that the linear array plate making exposure head that the present invention proposes cooperates existing dot-matrix printer to constitute the embodiment synoptic diagram of an available linear array plate-making printer.
Light emitting diode in the accompanying drawing 1 aims at the optical-fibre communications design originally, except the light emitting diode that resembles ordinary construction, have simulation or pulse or the analog pulse compound controlled electrical input terminal (1) and tube core shell (2), self also have can high-level efficiency the light transmitting fiber output terminal (3) of the light that sends of output tube core.Here (1), (2) are electric light sources, and (3) are that optical shaping is assembled device, and (1), (2), (3) structurally are incorporate.The light transmitting fiber output terminal (3) of a plurality of such light emitting diodes is lined up linear array (4) on plane of exposure (5), just constituted a kind of linear array plate making exposure head.
Accompanying drawing 2 is that the vertical line direction of accompanying drawing 1 battle array along the line (4) draws through expansion, and the light transmitting fiber output terminal (3) of each light emitting diode is lined up face battle array (6) on plane of exposure (7), thereby has constituted a kind of matrix plate making exposure head.
The luminosity spectral characteristic of light emitting diode requires consistent or close with the spectral characteristic of film as far as possible, can add the school mating plate in case of necessity or proofread and correct by school optical software etc. on plane of exposure.Factors such as the definite main consideration operation property of light emitting diode drive controlling mode and circuit complexity, for example, making two light emitting diodes when transferring black and white versions or coloured edition can select the switch drive control mode of pulse for use, make the continuous drive control mode etc. that light emitting diode when having the black and white version of the above gray scale of two-stage or having coloured edition of the above colourity of two-stage can be selected simulation for use.Adopting variable color diode and analog-driven control mode is to make the suggested design of photochrome or color transparency or colored egative forme.Laser diode is a kind of mutation of light emitting diode, also can use, and product has also having of band light transmitting fiber output terminal not to be with the light transmitting fiber output terminal, cooperates infrared film to be well suited for quick Fabrication two and transfers black and white versions or coloured version.If resolution is enough high then need not extra optical shaping and assemble device and just can directly cooperate shell etc. to constitute linear array or face matrix plate making exposure head when using by the integrated linear array light emitting diode of integrated circuit technology manufacturing or integrated paroxysm optical diode.The also available integrated circuit technology of variable color light emitting diode and laser diode is made into the version of integrated linear array or integrated battle array, can use with reference to the using method of integrated linear array light emitting diode of making by integrated circuit technology or integrated paroxysm optical diode in the use.Common light emitting diode also can use as electric light source, just and the coupling efficiency between the light transmitting fiber very poor; Adopt collector lens can significantly improve coupling efficiency, but with the single-mode fiber coupling of inner core diameter below 10 microns the time technological requirement height some.
Electric light source select the semiconductor product that is not limited to light emitting diode and so on for use.Electroluminescent device or luminescence of plasma device also can be in order to constitute linear array or the face battle array photosensitive lithographic photohead that the present invention proposes; Incandescent lamp bulb and before be used for the picture dot pipe of large screen display and their derivation device also can use, for example the optical fiber that is divided into three branches with an end according to the principle of three primary colours in the color TV technology is coupled to the output of the picture dot pipe of the incandescent lamp bulb of three red, green, blue three primary colours or three red, green, blue three primary colours and constitutes linear array or face matrix plate making exposure head etc. together.Other electric light source or electric light source assembly copy above-mentioned example all can consider to select for use during concrete enforcement.
Converged optical lens assembles device as optical shaping and can use separately, also can use instead mutually or use with light transmitting fiber.If for example above-mentioned light emitting diode, integrated linear array light emitting diode, integrated paroxysm optical diode, electroluminescent device, luminescence of plasma device, incandescent lamp bulb, picture dot pipe and their derivation device etc. and back will be mentioned the not high enough then available converged optical lens of the resolution of liquid crystal light valve plate and its convergence is narrowed down to satisfy desired high resolving power level; And for example originally lower the even light-emitting diode display panel assembly that we can say 5 * 7 very low dot matrix of resolution be available light lead fiber to its shaping reset, also available converged optical lens narrows down to its convergence and satisfies desired high resolving power level etc.;
Common light transmitting fiber is made of inner core (8) and covering (9), please referring to accompanying drawing 3.By also allowing the light that enters covering not be reflected on the plane of exposure basically in the optical fiber short distance of curling, this means that resolution is mainly determined by inner core.But the existence of covering will influence the acquisition of best resolution in accompanying drawing 1, accompanying drawing 2, the way that solves is to adopt improved directrix battle array plane of exposure, as shown in Figure 3: previous linear array is taken out point, reorganization, lined up few several row of trying one's best again by the tangent principle of the inner core of adjacent two row optical fiber and same horizontal linear, it is not overlapping to make each fibre-optic inner core projection in the horizontal direction not leave a blank yet, pass through software compensation during work, proofread and correct because of reorganization and arrange the phase differential of introducing again, feasible exposure to sensitive film still is one dimensional linear array on form.Certainly, if in the directrix battle array plane of exposure given light transmitting fiber be need not to pursue its best resolution etc., then each fibre-optic inner core projection in the horizontal direction can leave a blank, also can be overlapping; For ease of process and assemble, row's columns also can be more again in previous linear array reorganization.
The vertical line direction of directrix battle array plane of exposure battle array along the line can obtain accurate face battle array plane of exposure through expansion.
Face battle array liquid crystal light valve plate of forming with the many liquid crystal light valves unit (12) with two-dimensional array in the accompanying drawing 4 (11) and back reflection photography iodine-tungsten lamp (10) are realized the face matrix plate making exposure head that the present invention proposes.Can realize the linear array plate making exposure head that the present invention proposes with linear array liquid crystal light valve plate and back reflection photography iodine-tungsten lamp that the many liquid crystal light valves unit with one dimension arrangement is formed.Liquid crystal light valve can not active illuminating thereby is needed could work as the back reflection light source by means of the photography iodine-tungsten lamp, and modulation is carried out at liquid crystal light valve, and the consideration of other link and front roughly the same.Back reflection photography iodine-tungsten lamp can be used other electric light source or electric light source assembly instead, is added with softbox or thermal insulation board in case of necessity between they and the liquid crystal light valve plate.Adopting color liquid crystal light valve panel and analog-driven control mode is to make to have the photochrome of rich colors or the suggested design of color transparency or colored egative forme.
Select for use different types of electric light source and optical shaping to assemble device many kinds of structures that go out except that above-mentioned example also capable of being combined, can reasonably select with reference to above-mentioned example when specifically implementing, no longer one by one introduction.
