Description
Technical field
The present invention relates to a kind of roller and its manufacture method, more particularly, to a kind of laser aufhellung roller and its manufacturer
Method.
Background technology
Electric carving intaglio plate is to apply a kind of most common printing plate in current domestic flexible package gravure industry, and its technological process connects original text
- text design and layout-machining-copper facing-electric carving-chromium plating-are drawn a design-is examined eventually with going over a manuscript or draft.This electric carving intaglio plate is because the net of version
Shape is the structure of V-shaped so in order to ensure quantity of ink, carving depth and copper layer thickness will be high, the problem of existing mainly have with
Under several aspects：
1st, the V-shaped structure site of electronic engraving is unfavorable for transfer of the ink in printing.
2nd, the ink usage during printing plate printing of the V-shaped structure site of electronic engraving is big.
3rd, electric carving intaglio plate thickness of coated copper layer will generally reach 120 microns, and consumption raw and auxiliary material and the electricity charge are big.
4th, electric carving intaglio plate chromium coating thickness will generally reach 12 microns, and consumption raw and auxiliary material and the electricity charge are more.
5th, because the site of electronic engraving masters often big to 40--60 microns, often there is phenomenon of having an injection, cause engraving needle
Scrap and done over again with roller.
6th, image section is smudgy, and level effect is poor, and the shadow of image is partially shallow or too deep image section is smudgy, layer
Secondary effect is poor, and the shadow of image is partially shallow or too deep, electronic engraving word, the illegal elimination of jagged edge of lines, optical clarity
Degree is bad, and 5 points are difficult to see with lower word.
7th, because electronic engraving leader is difficult uniformly, to cause gradient prints uneven.
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 a kind of cost-effective, picture and text
Definition high laser aufhellung roller and its manufacture method.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of laser aufhellung roller, including roll body, and the central shaft being connected with roll body, described roll body include version cylinder and
The symmetrical plug for being fixed on version cylinder two ends, described central shaft passes through two plugs and is secured to connection, and described version cylinder is by interior
To outer setting nickel coating, copper plate and chromium coating, described roller is using laser aufhellung version site.
Described laser aufhellung version site is U-shaped structure.
The carving depth of described laser aufhellung version site is 12 microns.
Described thickness of coated copper layer is 40-60 microns.
Described chromium coating thickness is 6 microns.
The surface roughness of described roller is Ra0.2。
Described roller is exposed using 6400dpi laser.
A kind of manufacture method of laser aufhellung roller, comprises the following steps：
1) prepared by roller；
2) electrolytic degreasing；
3) nickel plating；
4) copper facing；
5) copper grinding stone is ground；
6) ultrasonic cleansing；
7) kiss-coating；
8) rotary drying；
9) laser explosure；
10) corrode；
11) photoresists are peeled off
12) chromium plating
13) chromium paper is ground.
Compared with prior art, the present invention has advantages below：
1st, laser aufhellung intaglio plate technology reduces the thickness of plating as a result of special ink cell, makes the material of plating
The thickness that consumption can cut down 60% plating is directly relevant with material consumption, the electroplating thickness system recommended of being made a plate using high-definition laser
Version, has not only cut down fee of material, while the consumption of additive is also cut down.As shown in table 1：
Table 1
2nd, maximum can save ink 30% during the intaglio printing of laser aufhellung.The high-resolution printing plate of laser aufhellung intaglio plate is than tradition
Electronic engraving version averagely cut down quantity of ink 30%, using new plate-making technology, realize at the optimization process of laser technology
Reason, and the text quality to only have laser can be only achieved, carry out the independent assortment of a variety of sites, make gradation fresher
It is gorgeous.
The consumed energy is dried when printing the 3rd, can be reduced, is conducive to, print speed printing speed is improved.
4th, 25% or so is reduced using the consumption of ink during aufhellung intaglio printing.
5th, with the reduction using ink, printing cost is saved, while ink setting is used when can reduce printing
Energy and time, and improve print speed printing speed.
6th, picture and text definition：Laser aufhellung intaglio plate uses newest 6400dpi laser, and High Resolution makes the definition of picture and text
There is very big advantage than traditional electric carving version.
