Description
Technical field
A kind of method that the present invention relates to laser plate-making, especially relates to a kind of semi-submerged etching laser plate making method.
Background technology
Existing caustic solution is the etch of fountain; ferric chloride corrosive liquid injects directly on the space of a whole page through filtration and corrodes; etching time is short; general with second control corrosion rate parameter; the bad control of background color version that corrosion word version, anti-counterfeiting plate, large area are shallow, often repeats the quality problems of same type:
1, the corrosion of large-area roller is irregular；
2, cigarette-brand is false proof or word version was corroded；
3, the space of a whole page that pattern is many corrodes and easily grows dim；
4, etching time is short, the bad control of the degree of depth to site, causes the poor repeatability of laser etched plate technological parameter；
5, spray corrosion is relatively big to the pressure of site, and air pressure forms acid mist ferric chloride corrosive liquid, beats and easily erodes glue on site.
There is the use of production and the client badly influencing laser version in these quality problems repeatability.Personalized product is more at present, and ordinary electronic engraving can not meet the demand of character product, and more customer selecting uses laser engraving, and etching plate technique carrys out printed product, and this just requires that the technique of laser plate-making is more stable, and the concordance of technological parameter is higher.
Summary of the invention
Defect that the purpose of the present invention is contemplated to overcome above-mentioned prior art to exist and a kind of site concordance solving laser version is provided, one is that the site of justifying same process wants consistent, two is that the dot parameters that laser version is repeatedly remake wants consistent, thoroughly solving corrosion irregular, the space of a whole page grows dim and corrode the semi-submerged etching laser plate making method of the partially deep phenomenon such as the most shallow.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of semi-submerged etching laser plate making method, comprises the following steps:
(1) copper facing version primary surface carries out kiss-coating or glue spraying, forms layer of surface protection glue-line on surface, then by laser engraving machine, pattern is carved on glue-line；
(2) the copper facing version base of engraving good pattern is placed in rinse bath and carries out pre-etching；
(3) after pre-etching terminates, copper facing version base is placed on the wheel of etching tank, first open rotating switch to start to rotate by copper facing version base, then start in being dipped into corrosive liquid by direction switch by copper facing version base 1/3rd surface to corrode, finally obtain the copper facing plate containing desirable pattern.
Prewashed chromium trichloride corrosive liquid it is loaded with in described rinse bath.
The ferric chloride corrosive liquid that mother-in-law U.S. degree is 15～20 it is loaded with in described etching tank.
Described rinse bath and the open type cell body that etching tank is integral type structure, equipped with the trachea with row's aperture under cell body, open air valve and make corrosive liquid circulate up and down during corrosion, strengthen the mobility of corrosive liquid, make iron ion more preferably contact with copper ion, improves corrosion rate.
The two ends of described cell body equipped with the drivewheel of liftable support roller axle and driven pulley, when pre-etching and corrosion copper facing version base alter thick stick or axle is placed on drivewheel and driven pulley.
Compared with prior art, the invention have the advantages that
(1) half immersion corrosion, a roller surface part is corroded in being contemporaneously immersed in corrosive liquid, can be prevented effectively from space of a whole page corrosion irregular；
(2) groove internal corrosion liquid mother-in-law U.S. degree 15～20, the average each needs of corrosion depth 1 minute, good control；Spurt method corrodes less than 3 only to be needed 20 seconds, corrodes the most wayward, easily corroded；
(3) groove internal corrosion liquid can repeatedly use, and reduces the discharge of waste liquid, can be cost-effective；
The generation of the other problemses such as (4) half immersion are corroded space of a whole page surface size no pressure, can effectively prevent glue, hot spot, before this advantage, glue spraying or kiss-coating, it is not necessary to do polishing at copper face, reduces waste of material；
(5) half immersion are corroded out and are better than laser jet etching bottom site out, for the material of some more difficult transfers, such as aluminum foil material, can effectively solve the disconnected problem of printing；
(6) half immersion are corroded owing to being easily controlled, and can effectively reduce owing to personnel change the negative effect brought.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described in detail.
Embodiment
A kind of semi-submerged etching laser plate making method, is carried out by following steps:
Device fabrication: half immersion etching tank is that the cell body of open type is divided into two, side checks for cleaning, and opposite side is 15～20 built with ferric chloride corrosive liquid, mother-in-law U.S. degree, and temperature is room temperature 22 degree, and in the present embodiment, mother-in-law U.S. degree of corrosive liquid is 20；Equipped with the trachea with row's aperture under cell body, open air valve during corrosion and make corrosive liquid circulate up and down, strengthen the mobility of corrosive liquid, make iron ion preferably contact with copper ion, improve corrosion rate；The two ends of groove are equipped with the wheel of liftable support roller axle, are drivewheel, while being driven pulley, roller corrosion and clean time roller alter thick stick or axle is all placed with on the wheel of both sides；
Plate-making principle: copper facing version base first carries out kiss-coating or glue spraying carries out sealer, then by laser machine, pattern is carved on glue-line, so has on edition base and has just having of pattern part not have glue-line to protect；The space of a whole page is ready for corrosion after inspection, first chromium trichloride corrosive liquid is utilized to carry out pre-etching in cleaning side, on the complete wheel again roller being placed on corrosion cell body of pre-etching, first open rotating switch to start to rotate by roller, then start in being dipped into corrosive liquid by direction switch by roller 1/3rd surface to corrode；Reactive chemistry equation is: 2FeCl3+ Cu=2FeCl2+CuCl2；Open insufflation switch and accelerate the flowing of corrosive liquid.
Key problem in technology point: corrosion cell body opens wide, and roller surface is directly immersed in corrosive liquid；Cell body is additionally arranged at the bottom gassing pipe, makes corrosive liquid circulate in groove during corrosion；Increase movable supporting frame, it is also possible to corrode the roller shorter than cell body；Drivewheel can realize rotating；
Laser plate-making half immersion etch, final purpose is the site concordance in order to solve laser version, and one is that the site of justifying same process wants consistent, and two is that the dot parameters that laser version is repeatedly remake wants consistent, thoroughly solving corrosion irregular, the space of a whole page grows dim and corrodes the phenomenons such as partially deeply the most shallow.
Meaning: the exploitation of half immersion corrosion can well improve the success rate that laser version makes, and decreases doing over again of laser version, reduces cost of manufacture, improves production efficiency；Preferably services client, the use field making laser version is more extensive, increases the plate-making amount of company's laser version, obtains more profit.
