Abstract
The present invention relates to a kind of laser etch process of wallpaper printing roller, comprise the following steps: 1) clean roller; 2) roller surface kiss-coating; 3) glue-line on pair roller barrel surface carries out laser engraving, makes the components vaporize of corresponding wallpaper picture and text on glue-line; 4) corrosion treatmentCorrosion Science is carried out to the roller after laser engraving, make the surface corrosion of non-covering glue layer go out wallpaper picture and text; 5) glue-line of roller surface is cleaned; 6) at roller surface plating.Compared with prior art, the present invention has the advantages such as cost is low, simple and practical, printing effect is good.
Description
Technical field
The present invention relates to a kind of laser etch process, especially relate to a kind of laser etch process of wallpaper printing roller.
Background technology
The current roller for wallpaper printing generally adopts the mode of electronic engraving now, due to the engraving netting twine all very thick (every centimetre, 50-60 line) used, therefore after causing wallpaper printing, picture and text effect is very coarse, pattern edge sawtooth is obvious, well cannot embody gravure printing product fine and smooth, the feature of levels are rich, and be easy to damage graver cause plate-making cost increase.
Summary of the invention
Object of the present invention be exactly in order to overcome above-mentioned prior art exist defect and the laser etch process that a kind of cost is low, simple and practical, printing effect is good is provided.
Object of the present invention can be achieved through the following technical solutions:
A laser etch process for wallpaper printing roller, comprises the following steps:
1) roller is cleaned;
2) roller surface kiss-coating;
3) glue-line on pair roller barrel surface carries out laser engraving, makes the components vaporize of corresponding wallpaper picture and text on glue-line;
4) corrosion treatmentCorrosion Science is carried out to the roller after laser engraving, make the surface corrosion of non-covering glue layer go out wallpaper picture and text;
5) glue-line of roller surface is cleaned;
6) at roller surface plating.
Step 2) adopt glue spreading machine evenly to apply one deck anticorrosion glue at roller surface.
Step 3) laser engraving important technological parameters index:
(1) roller breadth 200-2000mm, roller diameter 120-450mm;
(2) diameter tolerance ± 0.02, length franchise ± 3mm, increases progressively franchise ± 0.01mm;
(3) roller dynamic balancing≤20g;
(4) ink cell degree of depth 5S ~ ~ 40S;
(5) netting twine 10 ~ ~ 80l/cm is printed
(6) bondline thickness 10um, franchise ± 1um.
Step 4) in the roller after laser engraving is put into etching tank, rotating drum sprays corrosive liquid simultaneously.
Described corrosive liquid is ferric trichloride corrosive liquid, and the copper generation displacement reaction of this ferric trichloride corrosive liquid and roller surface, forms the ink cell of corresponding wallpaper picture and text.
Described protective layer is layers of chrome.
Compared with prior art, the present invention has the advantage of high netting twine, and the various degree of depth can ensure, there is no sawtooth, both ensure that the ink cell degree of depth that wallpaper printing needs, do not lost again the level texture of pattern, make the three-dimensional solid sense of the stereovision of printing and ink all fine, method is novel, and simple and practical, cost is lower.
Accompanying drawing explanation
Fig. 1 is flow chart of the present invention.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment
As shown in Figure 1, a kind of laser etch process of wallpaper printing roller, comprises the following steps:
1) pair roller barrel cleans, and makes roller surface meet the requirements of cleanliness factor;
2) apply one deck anticorrosion glue by glue spreading machine equably at roller surface, the object of this glue mainly protects the layers of copper of roller surface;
3) roller is loaded in laser engraving machine, controlling laser beam by laser engraving machine carves on glue-line by the wallpaper graph-text content of needs, the glue-line of corresponding wallpaper picture and text is vaporized off by laser beam, but not the glue-line of areas is still kept on roller, protection layers of copper;
Wherein, laser engraving important technological parameters index:
(1) roller breadth 200-2000mm, roller diameter 120-450mm;
(2) diameter tolerance ± 0.02, length franchise ± 3mm, increases progressively franchise ± 0.01mm;
(3) roller dynamic balancing≤20g;
(4) ink cell degree of depth 5S ~ ~ 40S;
(5) netting twine 10 ~ ~ 80l/cm is printed;
(6) bondline thickness 10um, franchise ± 1um.
4) roller is put in etching tank, rotating drum sprays ferric trichloride corrosive liquid simultaneously, corrode with ferric trichloride corrosive liquid, reach the applicable site degree of depth of wallpaper printing and size, the glue of corresponding wallpaper areas is because be vaporized, its exposed copper forms the ink cell of corresponding wallpaper picture and text with ferric trichloride generation displacement reaction, and the glue of non-graphic part is still retained on roller;
5) residual glue-line is washed away with cleaning fluid;
6) chromium plating is carried out on pair roller barrel surface, and the protection roller space of a whole page, improves resistance to print.
The present invention has the advantage of high netting twine, and the various degree of depth can ensure, there is no sawtooth, both ensure that the ink cell degree of depth that wallpaper printing needs, do not lose again the level texture of pattern, make the three-dimensional solid sense of the stereovision of printing and ink all fine, relative to common technique, simple and practical, cost is lower.
