Abstract
The present invention relates to a digital laser flexible plate capable of generating the visual false-proof effect on printed products. The present invention comprises a printing plate and is characterized in that the printing plate mesh points which can be positioned in one region or many regions are mesh points having various line numbers; or the printing plate mesh points which can be positioned in one region or many regions are mesh points having various angles; or the printing plate mesh points which can be positioned in one region or many regions are mesh points having various shapes; or the printing plate mesh points which can be positioned in one region or many regions of some one color plate are in a mesh point type formed by mixing two kinds of angles or three kinds of angles; or the printing plate mesh points are mesh points having various line numbers, different shapes and different angles. The present invention utilizes the potentiality of modern production tools, breaks through the technique mode of the traditional flexible plate making technology, and variously changes the mesh point structures of pictures and letters on the digital laser flexible plate. As a result, the flexible plate manufactured by the technique can be used for printing out various products having the visual false-proof effect.
Description
(1) technical field
The present invention relates to a kind of flexo plate-making art, relate in particular to and make the flexo product can produce the digital laser flexographic plate of visual false-proof effect.
(2) background technology
The tradition flexography generally all is to adopt with a kind of circular shaped lattice point, and version son of all kinds all is the screen line number that adopts with a kind of thickness, and each look version all adopts the site angle system flexographic printing oneself stipulated again.Such printing has the unicity of lattice point structure undoubtedly, visually has the consistance of presentation, is difficult to produce false proof function.
(3) summary of the invention
The object of the present invention is to provide a kind of digital laser flexographic plate that makes printing product produce visual false-proof effect that has.
First kind provided by the present invention has the digital laser flexographic plate that makes printing product produce visual false-proof effect, comprises forme, is characterized in: the site on this forme is the site with multiple not collinear number, difformity, different angles.
Above-mentioned technical solution, be the potential that utilizes the modern production instrument, break through traditional flexible mask-making technology technology mode, make the lattice point structure of made digital laser flexographic plate picture and text that multiple variation take place, thereby reach flexographic plate, can print off multiple product and come with visual false-proof effect with this kind fabrication techniques.
(4) description of drawings
Fig. 1 is that two kinds of lines of the present invention are counted enlarged diagram;
Fig. 2 is two kinds of angle enlarged diagrams of the present invention;
Fig. 3 is two kinds of dot shape enlarged diagrams of the present invention;
Fig. 4 is that the present invention is with two kinds of angle enlarged diagrams of version of the same colour;
Fig. 5 is the multiple screening technology enlarged diagram of the present invention.
(5) embodiment
As shown in Figure 1, first kind of digital laser flexographic plate provided by the present invention is characterized in: the local picture and text structure of this edition can be made up of multiple different screen line number, thereby makes the flexo product have the function of visual false-proof.For example, image subject is made of the high netting twine of 175 line/inches, and scenery is made of 80 line/inches or the low netting twine of 100 line/inches, and synthesizes in whole pair of flexographic plate.So that the flexo product are because of the different visual effects of site thickness, the relation of differentiate between images primary and secondary.
As shown in Figure 2, second kind of digital laser flexographic plate provided by the present invention is characterized in: the local picture and text structure of this edition can be made up of multiple different sites angle.For example, the red version of image is used the 45 netting twine, but the red version at other position is different with the whole space of a whole page suddenly in image, becomes 30 ° or 60 ° of angle netting twines.Make originally the flexographic plate that will make respectively of two cover different angles, make it to merge on same registering, thereby make these width of cloth flexo product have special visual false-proof function.
As shown in Figure 3, the third digital laser flexographic plate provided by the present invention is characterized in: the local picture and text structure of this edition can be made up of multiple different dot shapes.For example, personage's colour of skin is made of circular shaped lattice point, and background is made respectively of square and chain site, makes it to merge in same registering.Thereby make these flexo product have special visual false-proof effect.
As shown in Figure 4, the 4th kind of digital laser flexographic plate provided by the present invention, be characterized in: the local picture and text structure of this edition is in a certain regional area of some look versions, can be with the site of two or three different angles, the reticulate pattern form of Jiao Chaing simultaneously, be produced in the regional area of this version of the same colour, thereby make in this zone of flexo product, occurring seeming originally will be by two folded mutually special visual false-proof effect of mutually homochromy version different angles.
As shown in Figure 5, the 5th kind of digital laser flexographic plate provided by the present invention, be characterized in: can be above-mentioned four kinds of special process technologies, by printing preceding structural design to the false proof needs of difference, be produced among the different separately zone of each look version of a product cross-synthesis, carry out comprehensively synthesizing, make the flexo product that print off have the effect of the different visual false-proofs of diversity, multizone.
A kind of flexo product that make of the present invention have anti-fraud functional digital laser flexographic plate method for making, comprise the following steps:
1) before seal in the technology establishment, every width of cloth is needed the coloured image and the literal of anti-counterfeit structure, carry out zone design, get rid of in advance because the Moire fringe or the informal synthetic structure that may occur behind the not collinear number of each group, angle, shape site phase double exposure.
2) in computing machine, to the various colored picture and text of need system anti-counterfeit structure, retouch outbound path, carry out Region Segmentation.
3) press design code, formulate the requirement of flexographic plate laser engraving of different screen line numbers, site angle and the dot shape of not homochromy version, zones of different.
4) the short relatively zone of zone that all screen line numbers are thick more and net form girth, because the site overall circumference can shorten to some extent, the dot gain value diminishes relatively when causing flexographic printing.Therefore,, provide the characteristic compensation curve of a corresponding raising site percentage, so that false proof flexo product can reduce the color contrast of picture and text in the computing machine by different net forms and not in the dot area of collinear number.
5) zone of high screen line number of Antiforge should meet the corresponding data of concrete flexible printing press net roller line number.
Claims (1)
1, a kind of have a digital laser flexographic plate that makes printing product produce visual false-proof effect, comprises forme, and it is characterized in that: the site on this forme is to have the site of multiple not collinear number, difformity, different angles.
