Description
Technical field
This utility model belongs to printing technology, be specifically related to a kind of polychrome netting twine double exposure hits net simulation tool.
Background technology
At present, flexographic plate polychrome netting twine double exposure generally to select damp identical plate-making line number, set screen angle (such as 7.5 degree, 37.5 degree, 67.5 degree, 82.5 degree), formed objects and generally circular in cross section site to shield printing reticulate pattern and interference fringe.
Above-mentioned line number i.e. screen frequency, unit is L/IN, and namely per inch has how many sites. Such as, 300L/IN is that is per inch has 300 sites, and 150L/IN is exactly 150 sites of per inch, and the image of line number more high representative printing is more clear. The coverage rate (%) of site size and site, site is more big, and the inking of unit are is more many, and color is also deeper. And polychrome netting twine double exposure is the netting twine double exposure of more than dichromatism (yellow, blue or green, pinkish red, black, spot color), produced the printing effect of the third required color by the superposition of two or more basic colors.
In plate making, the selection of angle of halftone screen line has vital effect, if selecting the angle of halftone screen line of mistake, it will the printing defect such as reticulate pattern and interference fringe occur. But, in actual printing process, even if adopting above-mentioned first retainer and circular shaped lattice point, the printing defect such as reticulate pattern and interference fringe and the printing of difference is made a plate line number, different sites size also can not be shielded completely, selected screen angle is not quite similar, therefore, adjust angle, it is necessary to just can know effect after the printing every time, thus it is very difficult, loaded down with trivial details to cause obtaining corresponding best screen angle, and also improve Financial cost.

Detailed description of the invention
Polychrome netting twine double exposure of the present utility model hits net simulation tool as shown in Figure 1, it includes base 1, fixed pointers 2 and a pair film 3, fixed pointers 2 is vertical in the card 11 of base 1, as shown in Figure 2, two films 3 are square, rectangle or other shape, which is provided with identical round simulation region 4, in two round simulation regions 4, at least screen frequency is identical. Preferably, screen frequency in two round simulation regions 4, dot shape, site size are all identical, and regional center is equipped with a perforation, two films about 3 are overlapping and are sheathed in the card 11 being placed in base 1 in fixed pointers 2 by boring a hole, it is possible to horizontally rotate with fixed pointers 2 for axle center respectively. Described round simulation region 4 is equipped with angular coordinate, and described round simulation region 4 is equipped with coordinate axes. So, when wherein a film 3 rotates, simulation double exposure between two round simulation regions 4 hits net effect (such as printing reticulate pattern and interference fringe etc.) can be changed with the change of the anglec of rotation, by and observe printing reticulate pattern and the interference fringe situations of simulation in two round simulation regions 4, to obtain the best angle of halftone screen line of correspondence.
It should be noted that at this, film 3 can be as required, such as different screen frequencies, different dot shapes, different site sizes and combination (such as Fig. 2-Fig. 6), make multipair accordingly, the above-mentioned parameter of every a pair film 3 is all identical, during simulation, only need to carry out according to the actual requirements selecting corresponding a pair film 3 to use.
When making film 3, the only a kind of site size in the round simulation region 4 of film 3 can be made, for instance the site size in whole round simulation region 4 is all 30%; Can certainly adopt and described round simulation region 4 is radially divided into several subregion, site between each subregion varies in size, such as Fig. 2, this round simulation region 4 is divided into upper and lower two subregions by axis of abscissas, upper subregion varies in size with the site in lower subregion, namely the site gone up in region is sized to 30%, site in lower region is sized to 20%, so, when rotating again after film 3 alignment that two such is identical, in 180 �� of rotating ranges, it is possible to simultaneously observe two kinds of respective double exposures of site size and hit net effect. Certainly, according to symmetry principle, also by coordinate axes in length and breadth, round simulation region 4 being divided into four subregions, each subregion is a kind of site size, just can observe in 90-degree rotation that the double exposure of site size four kinds different hits net effect, has saved cost more. It addition, be more than site size, also as required, in each subregion, other different parameters or parameter combination can be adopted, to obtain corresponding effect.
The card 11 of base 1 is circular, adopts transparent material to make, and is provided with lighting source 5 in the inside of base 1, by lighting source 4 in back illuminated, it is possible to convenient, clearly observe simulation effect.
Double exposure that net simulation tool carries out hits net simulation (test) method to adopt polychrome netting twine double exposure of the present utility model to hit, and specifically includes following steps:
A. according to simulation demand, select a pair film 3 of relevant parameter, and this film 3 to have the screen frequency in identical round simulation region 4 and two round simulation regions 4, dot shape, site size all identical, after the two overlapped alignment of film 3, it is placed in the fixed pointers 2 of base 1 by central hole;
B. rotate a wherein film 3 according to the angular coordinate arranged on round simulation region 4, and observe the printing reticulate pattern in two round simulation regions 4 and interference fringe situation, and obtain the best angle of halftone screen line of correspondence.
Step b specifically comprises the following steps that
B1. first the round simulation region 4 of two films 3 is positioned to zero-bit;
B2. rotate a wherein film 3, and net effect is hit in range estimation;
B3. select optimum efficiency, and carry out Taking Pictures recording visual effect, record angle of halftone screen line now and the site size of correspondence, screen frequency, dot shape.
After the parameter of record is imported to the specific place of product documentation, again through corresponding process parameters design, RIP, plate-making, finally print by this, the printing effect of the best can be obtained, it is to avoid the printing defect such as reticulate pattern and interference fringe occurs.
But, those of ordinary skill in the art will be appreciated that, above embodiments is intended merely to explanation this utility model, and it is not used as to restriction of the present utility model, as long as in spirit of the present utility model, the change of embodiment described above, modification all will be dropped in Claims scope of the present utility model.
