Description
Technical field
The present invention relates to silk-screen printing field, and work is manufactured more particularly, to a kind of half tone being exposed using collotype
Skill.
Background technology
Silk-screen printing belongs to porous printing, and it is collectively known as four big printing processes with flat stamping, convex print, gravure.Hole version print
Brush includes stencil, engraves hole flower stencil, spraying decoration and silk-screen printing etc..
Silk-screen printing general principle：Using half tone need printing mesh can saturating ink, non-printing part mesh is not
The general principle of strike through is printed.Ink is poured on screen printing forme one end during printing, with oil of the scraper plate on screen printing forme
Black position applies certain pressure, while is moved towards the screen printing forme other end.The ink net by scraper plate from printing on the move
It is expressed in hole on stock.
The principle that half tone makes, be using emulsion (or being " photoresists ") to the chemical reaction of ultraviolet and
The opening that is formed carries out photosensitive lithographic after silk screen latitude and longitude interweave so that the emulsion of non-printing part by photo-hardening and
Mesh is blocked, and prints part then because of emulsion not after chemical reaction, can be dissolved and airbreak when meeting water.This technique
As exposure, development.
In exposure, the film film for the figure for describing printing in need is sticked on into half tone surface, the partial graphical is
Black, when ultraviolet irradiates, ultraviolet is sheltered from, remainder ultraviolet passes through film film by the emulsion on half tone
Solidification.
Film film is made up of chip base and sensitive emulsion layer.The material of sensitive emulsion layer is silver halide.High-precision laser is retouched
Draw equipment to be irradiated film film according to the data editted, promote silver halide to decompose, become black Argent grain, pass through
Cross fixing, the development of specific decoction so that the black graphics consistent with design original text are produced on film film.
But the film film of PET sheet base, the change to humiture is more sensitive, the figure after change occurs in humiture
Size also occurs change or even exceeds acceptability limit.And the easy injured of film film, the scuffing of PET sheet base, acid and alkali-resistance, is not used
Life-span is shorter.And with the continuous development of solar cell, PCB, IC package industry, increasingly thinner to the width of printed pattern,
Dimension precision requirement more and more higher.
Chinese patent CN104339900A discloses a kind of silk-screen printing technique, generally comprises and prepares screen printing forme, prepares
Photoresists, the processing steps such as photoresists, upper photoresists, exposure, development, maintenance, examination printing and formal printing are prepared, and in this work
Careful process modification has been carried out on the basis of skill step.But the patent application is still the PET film films, easily because warm and humid
The change of degree causes changing for size, and PET materials are easier to injured scuffing.
The content of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide one kind is replaced using collotype
The technique for carrying out half tone making for film film.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of half tone manufacturing process being exposed using collotype, using following steps：
1) collotype is placed on exposure machine platform according to positioning, figuratum one upwardly；
2) collotype is cleaned；
3) half tone is cleaned；
4) by the P of half tone downwards, it is placed on according to positioning on collotype；
5) the suitable time for exposure is selected to be exposed；
6) said process is repeated, manufacture obtains half tone.
The substrate of described collotype is typically high-purity, antiradar reflectivity, the quartz glass or soda of low thermal coefficient of expansion
Glass, be not in easy injured, scuffing, and the situation of harmomegathus occur with humiture change.
In addition, glass pane surface film layer uses crome metal, the thickness of film layer will relative to the halogenation silver film of film film
Low, the effect of shield lights is more preferable.What the width of lines can make than the film after photoetching is thinner, and the imaging of line edge
Acutance can reach 0.1-0.2um.
As preferable technical scheme, the thickness of crome metal film layer is in 0.1-0.15um.
The surface of described collotype is provided with crome metal film layer
Step 2) specifically uses following methods：Brushed away using antistatic except the electrostatic on glass plate, it is spirituous using being stained with
Non-dust cloth cleaning glass window plate removes the dust foreign matter of glass pane surface.
Step 3) specifically uses following methods：Half tone is placed on light table, throws off the PET film on half tone surface, confirmation form
Whether face has the attachment of dust foreign matter, if any then being removed using dust sticking bar.
Step 5) is before exposure, it is necessary to calculate the time for exposure.The light of half tone receiving is determined using the length of time for exposure
Measure total value.The determination of time for exposure, with the thickness of the illumination (average light quantity) of exposure machine and sensitive emulsion layer, the type of silk screen
It is number relevant.Most important of which is that the illumination of exposure machine, it is therefore desirable to measured to the illumination of exposure machine.Last foundation exposure
The illumination of machine calculates the time for the light summation for meeting half tone needs, according to the illumination intensity of exposure machine and half tone measured daily
Silk screen model, the thickness of emulsion set the suitable time for exposure, and the final time for determining exposure is in 1-5 minutes.
The innovative point of most critical of the present invention is that, the film film of PET sheet base is instead of using collotype.Film film
It is required to remove every time, is fitted in after re-registrating on half tone.It can be wasted on time, after long-time use, cut on film,
Injured can influence the transmission of light in exposure, so as to have influence on figure.In addition, and because PET is to the sensitiveness of humiture, lead
Cause the change of film dimension of picture, it is necessary to suspend use after causing continuous exposure.
After collotype is placed on exposure machine platform by the application, it is not necessary to move, after upper half tone end exposure, clean glass
After glass plate, you can place by next half tone, activity time can be saved., can be with and influence of the humiture to glass substrate is small
Continuous exposure, without worry change in size the problem of.
Traditional film film, 0.000018/ DEG C of temperature expansion coefficient；0.000008/ DEG C of collotype temperature expansion coefficient.
Traditional film film, humidity expansion coefficient 0.000009/%RH；Collotype is not influenceed by humidity.
Traditional film film, not acid and alkali-resistance；Collotype acid and alkali-resistance.
Traditional film film, wear resistence are poor；Collotype wear resistence is good.
Traditional film film, 10 microns of minimum line slit width degree；1 micron of collotype minimum line slit width degree.
Traditional film film, Line-width precision ± 1 micron；Collotype Line-width precision ± 0.5 micron.
Traditional film film, overall length precision ± 10 micron；Collotype overall length precision ± 2 micron.
Traditional film film, service life are short；Collotype service life is grown.
The manufacture craft of half tone, essentially by the mode of exposure, by the pattern transfer on medium to half tone, medium
Can be film film or glass plate.The film film of PET materials is compared with glass plate, the change to humiture
More sensitive, in production, the size for the figure that can make to be transferred on half tone changes.In addition, precision and the imaging of the film
Acutance compares glass plate and wants poor, also influences whether the graphical effect of half tone figure.
