Description
Technical field
The utility model relates to a kind of intaglio printing plate roller, is specifically related to the laser gravure plate roller in a kind of intaglio press.
Background technology
On gravure printing roller, site is the least unit that forms printed patterns, and the shape presenting in the roller that do not coexist of gravure lattice point due to plate-making mode is difference to some extent also.The shape of site and the characteristic of ink are directly determining the quality of the pattern that prints, comprising the micro-shape of pattern edge.In some field, as the production field of radio frequency identification etching antenna, the micro-shape of the antenna edge that the edge micro-shape of printed patterns obtains final etching exerts an influence, and whether the micro-shape of antenna edge is straight smooth very large to the performance impact of product.
At present, the plate-making mode of intaglio plate mainly contains four kinds:
1. film etched plate.This kind of technique is to scrape photoresists on the roller surface of having plated copper layer, then sticks the film, exposure, development, etching, chromium plating.Due to technique more complicated, control difficulty larger, the uniformity of roller recasting is poor, is now just progressively eliminated.
2. laser straight engraving.Plating in the roller of zinc layer, with laser beam, directly the site of pattern is being burnt on zinc layer to then chromium plating.The defect of this kind of technique is no matter the site of burning is out edge or bottom, and all more coarse, it is also very rough causing the pattern edge printing to look.
3. electronic engraving version.This kind of technique is to adopt diamond engraving needle depiction in the roller of having plated copper layer, and the form by pattern with site embodies.This operating procedure is simple, convenient, fast, roller recasting uniformity is better, and the roller advantage of making common gravure product is comparatively obvious.
Electronic engraving version, due to the limitation of engraving needle, can only be carved rhombus site, shown in Figure 1, and electric carving version all adopts diamond engraving needle on gravure printing roller 1, to carve site 120 for rhombus site, and pattern edge also has a lot of little sites to produce.During gravure printing roller printing, the transfer amount of ink and the shape of site and size are closely related, site, edge is not of uniform size, cause the transfer amount of ink inconsistent, the levelability of ink also will be received impact, thereby causes the pattern edge ink cladding thickness of printing inconsistent, and covers boundary line out-of-flatness, shown in Figure 2, pattern edge produces zigzag fashion.
4. laser version.This technique is to plate in the roller of copper layer, utilize the mode of frictioning or glue spraying to be coated with uniformly last layer photoresists, then according to the information requirements of intaglio plate e-file pattern, the laser beam sending with carbon dioxide laser is irradiated on gravure roller surface by speculum, condenser, fusing evaporation photoresists form the site needing one by one, these sites just in time form the corresponding pattern of original copy, then by etching and chromium plating, complete roller and make.
The feature of laser version plate-making mode is, in general, distance between the shape of all sites, size and site is all consistent, but to the site in pattern edge, when the edge of pattern boundary is passed these sites, due to the restriction that must be subject to pattern edge boundary of site, at this moment just there will be incomplete site.During due to printing, difformity is different with size site ink transfer amount, and the printing flatness of pattern edge will be affected.
For the feature of laser version, the current solution having adopted is at pattern edge, to increase the method in an astragal strip-shaped net hole, solves this problem, as shown in Figure 3.
But add linear network hole and can cause new problem again: first, after roller etching, the linear network hole increasing will become very thick, make pattern edge form a sunk ditch that there is no site and leader, during printing owing to there is no the support of leader, scraper will blow most of ink of this ditch the inside off, causes the pattern edge out-of-flatness of printing, and effect as shown in Figure 4.Secondly, for pattern circle or that other are crooked, effect neither be clearly.Due to the relation that arrange site, there will be the net hole at some places site and edge to be connected, form a very large site, during printing, ink is dense thick, forms obvious contrast with other place.
Chinese patent literature CN202037975U discloses a kind of laser gravure plate roller, the ink cell of densely covered regular shape in the district of site, between described ink cell, by net wall, separated, described ink cell is " U " type, the width of net wall is much smaller than the bore of ink cell, and described ink cell at least with on an adjacent net wall has the otch being interconnected.This design also can improve ink circulation, plays the effect of ink complementation between site, reduces the generation of water ripple phenomenon.But this design still adopts the site of rhombus, the planarization that pattern edge ink is covered does not have the effect improving.
In sum, for deficiency and the defect of existing gravure printing roller, need especially a kind ofly for avoiding printed patterns edge to occur the gravure printing roller of sawtooth, to improve the quality of printed patterns, address the above problem.
