Description
Technical field
The invention belongs to print field, particularly a kind of plate making equipment and method for platemaking.
Background technology
Mask-making technology is the important step before print in technique, plays the part of the role that this is very important in whole printing-flow, has extremely important impact to the color of printed matter, contrast and alignment.Along with the development of science and technology, mask-making technology also constantly develops thereupon, wax spray plate-making, ink-jetting forme-producing is developed into from conventional film plate-making, laser plate-making of so far widespread use etc., along with the development of computer technology, mask-making technology combines with it gradually, and towards the direction development of efficient, environmental protection, low cost, thus define Computer To Plate technology.
So-called Computer To Plate (Computer to Plate, be called for short CTP) be exactly use computing machine original copy character image through digitized processing and slot man, directly in the enterprising line scanning imaging of forme, then by development, the postprocessing working procedures such as fixing or exempt from aftertreatment and make forme.Have compared with traditional film printing down technique operation simple, without the need to slice, printing down and the advantage such as the plate-making cycle is short.
But the application of Computer To Plate equipment is limited by an important factor, i.e. light source restriction, superlaser has very important impact to plate-making quality and production efficiency.Adopt the restrictive factor of laser plate-making, the size of laser facula becomes negative correlation with energy efficiency, thus affecting ablation, imaging efficiency, complex process, capacity usage ratio is low, especially when imaging resolution requires higher, accuracy requirement is higher, and laser facula is less, and energy efficiency is lower, ablation, imaging time are longer, thus have elongated the production cycle.
No matter above-mentioned CTP also or CTcP platemaking equipment and technique, all relate to LASER Light Source, the precision of LASER Light Source directly impact plate-making in lithography process and yields, wherein mask-making technology parameter comprises: the determination (comprising dot spacing and some size), single-point ablation time, ablated area, imaging efficiency, laser power, dutycycle, plate threshold value, rate travel, step rate, lens ratio etc. of the size of laser facula.For improving plate-making quality and plate-making efficiency, being carried out adjusting by above-mentioned technological parameter and obtaining preferably technique effect is an extremely long job consuming time.In addition, along with operating lifetime and the performance degradation of LASER Light Source, technician need adjust its running parameter and other running parameters relevant at any time, causes the accumulation of error of different release, finally causes chromatography precision decline, printing quality reduction.
Existing research view introduces new light source to overcome above-mentioned defect, for Chinese patent application (application number: 201210399834.5), it discloses a kind of making apparatus and method for making of screen printing screens, it specifically discloses platemaking equipment and has following structure: comprise and setting gradually: a photoresists apparatus for coating, for half tone surface coating photoresists after the pre-treatment; One plate burning device, it comprises further: objective table, for being fixed by the half tone of coating photoresists; Printing down light source, comprising: according to the LED lamp of a determining deviation arrangement; Light source control device, for the forme pattern that makes as required to control LED lamp, makes LED lamp directly expose forme pattern on the half tone surface of coating photoresists; One cleaning equipment, for removing photoresists remaining on half tone.Described LED lamp is UVLED lamp.Concrete preparation technology is: S1, carry out pre-service to silk screen, and described pre-service comprises: the net that stretches tight, clean silk screen and drying; S2, to pretreated half tone surface coating photoresists; S3, by coating photoresists half tone be fixed on objective table; The data of the forme pattern that the needs that S4, light source control device receive input make, and regulate the light on and off of LED lamp, then make LED lamp expose forme pattern on the silk screen surface of coating photoresists; Photoresists remaining on the wire side of S5, removing half tone: unexposed photoresists are rinsed, and the photoresists after exposure are retained, and form version film.The basic thinking that this application adopts is, adopt the pointolite of array, namely LED array is as exposure light source, by controlling the opening and closing of LED independent in array, the exposing patterns needed for formation, after forme is exposed, the regions curing forme that LED is bright, the region that LED is gone out does not expose, thus eliminates the film, the i.e. use of film, achieves direct plate-making.But, there is following shortcoming in this technology: 1. precision is not high, as everyone knows, LED is pointolite, the array that LED is formed is that series of LED luminescence unit is spaced formation, the light that single led lamp sends not parallel beam completely, there is scattered light equally in the interval between LED, the luminescence of single led lamp is propagated with the form that strong edge, center is weak, especially LED and forme interval larger when, the light being positioned at the LED at image border place is radiated on forme and forms halation, thus cause fuzzy exposure figure edge, imaging precision is caused to decline, 2. cost is high, and LED array especially UVLED lamp adopts special semiconductor material usually, and this semiconductor material is wafer, and overall lithography process forms, and usually adopt CVD growth, its cost is high, 3. poor fault tolerance, easily because the factors such as productions, maintenance form bad point in LED array, namely LED luminescence unit can not normal luminous individually, and due to process technology limit, is difficult to change indivedual LED particle, thus causes monoblock LED array normally to use.
As can be seen here, in prior art, the technology barrier that prior art level and resolving ideas are difficult to go beyond is there is in CTP and the CTcP mask-making technology of especially widespread use, in order to solve, the investment in fixed assets existed in prior art is large, light source maintenance cost is high, life period of equipment is short, consumables cost high-technology problem, need transformation mentality of designing badly, provide a kind of structure simple, be easy to the next generation computer platemaking equipment safeguarded, plate-making cost is low.
